I have spent years working hands-on with different email marketing and automation tools, from basic newsletter platforms to advanced systems built around behavioral workflows. One thing I learned quickly is that many tools promise automation but struggle once you try to build real customer journeys.

This guide is based on my first-hand experience setting up campaigns, automations, and email funnels using the most widely recommended platforms on the market. Instead of repeating feature lists, I focus on how these tools actually perform in real use and where they start to feel limiting.

You will also see OptinMonster included. While it is not an email service provider, I have used it alongside nearly every tool in this list. Strong automation only works when it is fed with high-quality leads, and lead capture plays a bigger role than most people expect.

Below, I walk through each tool individually, starting with the platforms I rely on most for serious email automation.

Email Automation Software Compared

Hands-On Reviews of Email Automation Software

1. ActiveCampaign

I started using ActiveCampaign when basic autoresponders were no longer enough. At that point, I needed a platform that could react to user behavior and support real customer journeys instead of simple time-based sequences.

ActiveCampaign’s automation builder is one of the most flexible I have worked with. The visual workflow editor makes it easy to build multi-step automations with conditional logic, tagging, and goal tracking. I regularly use it to move contacts between funnels based on actions like page visits, link clicks, or purchases, which makes campaigns feel far more personalized.

One improvement I have appreciated in recent updates is the addition of AI-assisted automation setup. Instead of building everything manually, I can now describe what I want to achieve and let the platform generate a starting workflow. ActiveCampaign has also expanded its cross-channel automation, allowing email, SMS, and WhatsApp messaging to be managed from the same automation builder, which is useful when campaigns extend beyond email alone.

Feature Highlights

• Visual automation builder with advanced branching logic
• AI-assisted workflow creation to speed up setup
• Cross-channel automation including email, SMS, and WhatsApp
• Detailed tagging, segmentation, and lead scoring
• Built-in CRM and sales pipeline automation

ActiveCampaign works best for businesses that want automation tied closely to user behavior and lifecycle stages. I have found it especially effective for lead nurturing, onboarding sequences, and campaigns that need to adapt based on how contacts engage.

There is a learning curve, especially for beginners. Pricing can also increase quickly as your contact list grows and you unlock more advanced features.

Based on my experience, ActiveCampaign is a strong choice for teams that want serious automation without moving into full enterprise software. If your goal is to build behavior-driven email journeys that connect marketing and sales, this platform is hard to beat.

2. HubSpot

I have used HubSpot in situations where email automation needed to connect directly to CRM data, sales activity, and customer lifecycle stages. Compared to standalone email tools, HubSpot feels more like a full system than a single channel platform.

Email automation in HubSpot is built around its CRM, which changes how you work. Instead of creating automations based only on email behavior, I can trigger workflows from contact properties, deal stages, form submissions, page views, and sales activity. This makes it much easier to align marketing emails with what is actually happening in the pipeline.

In recent updates, HubSpot has leaned heavily into AI-powered tools. I have used its AI features to help draft emails, summarize CRM activity, and optimize subject lines. These additions do not replace strategy, but they do save time when managing large lists or complex workflows. HubSpot has also expanded its workflow actions, giving more flexibility when automating lead routing, internal notifications, and follow-ups.

Feature Highlights

• CRM-based email automation and workflows
• Visual workflow builder with advanced triggers and conditions
• AI-assisted email writing and optimization tools
• Deep integration with sales pipelines and deal stages
• Strong reporting and attribution across marketing and sales

HubSpot works best when email automation is part of a larger marketing and sales system. I have found it especially effective for teams that want marketing emails, lead scoring, and sales follow-ups to live in the same platform.

Cost is the biggest limitation. Advanced automation features are locked behind higher-tier plans, which can be expensive for small teams. It can also feel like more software than you need if email marketing is your only focus.

Based on my experience, HubSpot is ideal for growing teams that want email automation tightly connected to CRM and sales processes. If you need visibility from first touch through conversion and beyond, HubSpot does that better than most tools.

3. Klaviyo

I have used Klaviyo primarily in ecommerce environments where email automation needs to be tightly connected to revenue, product behavior, and purchase history. From the start, it is clear that this platform is built with ecommerce in mind, not as an add-on but as its core purpose.

What stood out to me right away was how easily Klaviyo pulls in data from ecommerce platforms. Purchase events, product views, cart activity, and customer lifetime value are all available as automation triggers without extra configuration. This makes it straightforward to build flows like browse abandonment, cart recovery, post-purchase follow-ups, and win-back campaigns that are directly tied to shopping behavior.

In its latest updates, Klaviyo has expanded its AI-driven features, especially around predictive analytics. I have used predictive metrics like expected next purchase date and churn risk to refine segmentation and timing. The automation builder itself has also improved, with clearer flow visualization and better tools for testing and optimizing performance across email and SMS.

Feature Highlights

• Ecommerce-first automation triggers tied to real purchase behavior
• Advanced segmentation using revenue, product, and engagement data
• Predictive analytics for churn risk and next purchase timing
• Email and SMS automation managed from the same platform
• Strong reporting focused on revenue attribution

Klaviyo works best for ecommerce brands that want automation driven by customer behavior and sales data. I have found it especially effective for stores running frequent promotions, product launches, or lifecycle campaigns tied to repeat purchases.

Klaviyo is less flexible outside of ecommerce use cases. If you are running a content site, SaaS product, or service business, some of its strengths may feel unnecessary. Costs can also rise quickly as your contact list and messaging volume grow.

Based on my experience, Klaviyo is one of the strongest options for ecommerce-focused email and SMS automation. If your priority is driving repeat purchases and tying automation directly to revenue, this is a platform worth serious consideration.

4. GetResponse

I have used GetResponse when I wanted a platform that offered solid automation without the complexity or cost of more advanced enterprise tools. It sits in a middle ground that works well for many teams, especially when you want more than newsletters but are not ready for a heavy CRM-driven setup.

GetResponse’s automation builder is straightforward and easy to work with. I was able to set up multi-step workflows using conditions based on email engagement, tags, purchases, and form submissions without much friction. The interface makes it clear how contacts move through automations, which helps when managing multiple campaigns at once.

In more recent updates, GetResponse has expanded its feature set beyond email. I have used its built-in funnels, landing pages, and webinar tools to support automation campaigns end to end. The platform has also added AI-assisted email creation features, which help speed up drafting subject lines and content when launching new campaigns.

Feature Highlights

• Visual automation builder with conditional logic
• Built-in funnels, landing pages, and webinar tools
• AI-assisted email content and subject line creation
• Ecommerce and purchase-based automation triggers
• Solid reporting for campaign and automation performance

GetResponse works best for small to mid-sized businesses that want automation plus supporting tools in one place. I have found it useful when running lead generation campaigns that combine email, landing pages, and follow-up sequences without relying on external software.

While capable, the automation is not as deep as platforms like ActiveCampaign or HubSpot. Some advanced segmentation and workflow options feel more limited once campaigns become highly complex.

Based on my experience, GetResponse is a good fit for teams that want dependable automation with a manageable learning curve. If you are looking for a balance between features, usability, and cost, it is a platform worth considering.

5. Mailchimp

I have used Mailchimp on and off for years, mostly for smaller projects and early-stage businesses that needed to get email campaigns running quickly. It has always been easy to start with, and that is still one of its biggest strengths.

Setting up basic automations in Mailchimp is straightforward. I have used it for welcome sequences, simple follow-ups, and re-engagement emails without much setup time. The interface is clean, and the email builder makes it easy to create campaigns without design experience.

In more recent updates, Mailchimp has expanded its automation features and added AI-powered tools. I have used its AI content suggestions and subject line helpers, which are useful for speeding up campaign creation. Mailchimp has also improved its customer journey builder, making it easier to visualize how contacts move through simple automation paths based on engagement and ecommerce activity.

Feature Highlights

• Easy-to-use email and automation setup
• Customer journey builder for basic workflows
• AI-assisted content and subject line suggestions
• Ecommerce integrations with purchase-based triggers
• Large template library and built-in design tools

Mailchimp works best for beginners and small businesses that want to launch email campaigns quickly without dealing with complex automation logic. I have found it useful for straightforward workflows where simplicity matters more than flexibility.

Automation depth is limited compared to more advanced platforms. Once workflows require detailed branching, advanced segmentation, or tight CRM integration, Mailchimp can start to feel restrictive. Pricing can also increase quickly as your list grows.

Based on my experience, Mailchimp is a good starting point for basic email automation. If you are just getting started or only need simple workflows, it does the job well. For more advanced automation needs, most teams eventually outgrow it.

6. Kit

I have used Kit primarily for creator-led projects where the focus was on content, subscriptions, and audience relationships rather than complex sales pipelines. It feels intentionally opinionated, and that shows in how automation is handled.

Kit’s automation is built around tags and visual rules instead of deep branching workflows. In practice, I found this makes it easier to manage subscriber journeys without overengineering them. I have used it to trigger sequences based on form signups, link clicks, purchases, and tag changes, all of which felt intuitive and quick to set up.

In its latest updates, Kit has expanded automation flexibility and improved its visual automation editor. I have also used its newer AI-assisted tools for email drafting and subject line suggestions, which help speed up content creation. The platform has continued to lean into creator monetization features, including paid newsletters and digital product automations, which integrate smoothly into email flows.

Feature Highlights

• Tag-based automation that is easy to manage
• Visual automation editor for subscriber journeys
• AI-assisted email writing and subject suggestions
• Built-in tools for paid newsletters and digital products
• Clean interface designed for creators

Kit works best for creators, bloggers, and educators who want automation without complexity. I have found it especially useful when managing content-driven funnels, lead magnets, and subscriber nurturing tied to personal brands.

Automation depth is more limited than platforms like ActiveCampaign or HubSpot. If you need complex branching logic, CRM features, or advanced segmentation based on many conditions, Kit may feel restrictive.

Based on my experience, Kit is a strong choice for creators who want email automation that stays out of the way. If your business revolves around content, courses, or audience monetization, it strikes a good balance between simplicity and control.

7. Brevo

I have used Brevo in projects where budget mattered, but I still needed reliable automation and transactional messaging. It stands out as a practical option when email automation needs to work alongside transactional emails and SMS without moving to a more expensive platform.

Brevo’s automation setup is straightforward. I have used it to build workflows based on email engagement, list activity, and basic behavioral triggers. While it does not offer the same depth as higher-end tools, it covers the essentials well and is easy to manage once automations are live.

In its more recent updates, Brevo has improved its automation editor and expanded its multi-channel capabilities. I have used it to combine email and SMS within the same workflows, which is especially useful for confirmations, alerts, and time-sensitive follow-ups. The platform has also continued to strengthen its transactional email infrastructure, which is one of its biggest advantages.

Feature Highlights

• Email automation with simple, clear workflow setup
• Built-in transactional email and SMS support
• Multi-channel workflows combining email and SMS
• Affordable pricing with generous free limits
• Solid deliverability for both marketing and transactional messages

Brevo works best for small to mid-sized businesses that need both marketing automation and transactional messaging in one platform. I have found it especially useful for SaaS products and service-based sites that rely on system emails as much as marketing campaigns.

Automation options are more basic compared to advanced platforms. Segmentation and workflow branching can feel limited once campaigns become more complex.

Based on my experience, Brevo is a strong option if you want dependable automation and transactional messaging at a reasonable price. If affordability and multi-channel basics are your priority, it is a solid choice.

8. MailerLite

I have used MailerLite in situations where simplicity and ease of use mattered more than advanced automation depth. It is one of the tools I reach for when I want to get campaigns and basic workflows running quickly without a long setup process.

MailerLite’s automation builder is clean and easy to understand. I have used it for welcome sequences, basic lead nurturing, and simple follow-ups triggered by signups or email engagement. The visual editor makes it clear how subscribers move through each step, which helps avoid mistakes when managing multiple workflows.

In recent updates, MailerLite has expanded its automation features and improved its email editor. I have also used its built-in landing pages and forms, which integrate smoothly with automations and make it easier to capture and route leads without external tools. The platform has added AI-assisted writing tools as well, which help speed up content creation for straightforward campaigns.

Feature Highlights

• Simple visual automation builder
• Easy-to-use email editor and templates
• Built-in forms and landing pages
• AI-assisted email content tools
• Affordable pricing with a generous free plan

MailerLite works best for small businesses, creators, and teams that want straightforward automation without complexity. I have found it useful for basic funnels where clarity and speed matter more than advanced logic.

Automation options are limited once workflows require advanced branching, deep segmentation, or CRM-style features. It is not designed for highly complex automation use cases.

Based on my experience, MailerLite is a good fit if you want a clean, affordable tool for basic email automation. If your needs grow beyond simple workflows, you may eventually need to upgrade to a more advanced platform.

9. Drip

I have used Drip mainly for ecommerce projects where email automation needed to react closely to customer behavior and revenue data, but where tools like Klaviyo felt heavier than necessary. Drip sits in an interesting middle ground between flexibility and focus.

Drip’s automation builder gives you more control than entry-level platforms. I have used it to build workflows triggered by purchases, browsing behavior, tags, and custom events. The visual workflow editor makes it clear how contacts move through each step, and it is easy to adjust logic as campaigns evolve.

In its more recent updates, Drip has continued to improve its ecommerce data integrations and automation flexibility. I have used its revenue attribution and customer timeline views to understand how email interactions connect to actual purchases. The platform also supports both email and SMS automation, which helps when coordinating campaigns across channels.

Feature Highlights

• Ecommerce-focused automation with behavioral triggers
• Visual workflow builder with flexible logic
• Revenue attribution tied to email performance
• Email and SMS automation in one platform
• Customer timelines that show engagement and purchase history

Drip works best for ecommerce brands that want more automation control than beginner tools but do not need a full CRM. I have found it useful for stores that want to fine-tune lifecycle emails and segment customers based on buying behavior.

Drip is less suited for non-ecommerce use cases. If you are running a content site or service business, some features may feel unnecessary. Pricing can also rise as your contact list grows.

Based on my experience, Drip is a strong option for ecommerce teams that want flexible automation without excessive complexity. If your focus is lifecycle emails and revenue-driven campaigns, it fits well.

10. Moosend

I have used Moosend in projects where cost was a major factor, but basic automation was still required. It is one of the more affordable tools I have worked with that still offers a visual automation builder rather than limiting users to simple autoresponders.

Moosend’s automation setup is easy to follow. I have used it to create workflows based on email opens, clicks, list subscriptions, and simple behavioral triggers. The interface is clean, and it does not take long to understand how contacts move through an automation. For straightforward campaigns, this makes setup fast and predictable.

In its more recent updates, Moosend has improved its automation editor and reporting. I have also used its newer AI-powered subject line and content suggestions, which help speed up campaign creation. Ecommerce integrations have improved as well, making it easier to trigger emails from basic purchase activity.

Feature Highlights

• Visual automation builder with essential triggers
• AI-assisted subject line and content suggestions
• Ecommerce integrations for basic purchase automation
• Affordable pricing compared to most competitors
• Clean interface that is easy to manage

Moosend works best for small businesses and teams that want automation at a low cost. I have found it useful for simple lead nurturing, onboarding sequences, and promotional follow-ups where advanced logic is not required.

Automation depth is limited compared to higher-end platforms. Segmentation options are more basic, and complex workflows can feel constrained once campaigns grow.

Based on my experience, Moosend is a good choice if budget is your primary concern and you still want basic automation capabilities. It covers the essentials well but is not built for advanced or highly customized workflows.

11. AWeber

I have used AWeber mostly for long-running lists and smaller businesses that value stability and deliverability over cutting-edge automation. It is one of the older platforms in this space, and that shows in both good and limiting ways.

AWeber’s automation is centered around campaigns triggered by tags, signups, and basic engagement. I have used it for welcome sequences, lead magnet delivery, and simple follow-ups without issues. The setup process is straightforward, and the interface feels familiar if you have worked with traditional email marketing tools before.

In its more recent updates, AWeber has improved its automation editor and added AI-assisted tools for writing subject lines and email content. I have also used its landing pages and signup forms, which integrate cleanly with automations and help reduce reliance on external tools for basic lead capture.

Feature Highlights

• Tag-based automation for simple workflows
• Reliable email deliverability
• AI-assisted subject line and email content tools
• Built-in landing pages and signup forms
• Easy setup for beginners

AWeber works best for small businesses and creators who want dependable email marketing with light automation. I have found it useful when running straightforward campaigns that do not require complex branching or advanced segmentation.

Automation options are limited compared to more modern platforms. If you need advanced behavioral triggers, deep segmentation, or ecommerce-focused workflows, AWeber may feel outdated.

Based on my experience, AWeber is a solid option if you value simplicity and reliability over advanced automation. It is a good fit for basic email marketing needs and long-term list management.

12. Campaign Monitor

I have used Campaign Monitor mainly when design quality and brand presentation were the top priorities. It has always been strong on the visual side, and that remains its biggest differentiator compared to more automation-heavy platforms.

Campaign Monitor’s automation tools are easy to work with, but they are clearly designed for simpler workflows. I have used it for welcome emails, basic drip campaigns, and follow-ups triggered by engagement or list activity. The visual journey builder is clear and intuitive, which makes it easy to manage straightforward sequences without confusion.

In its latest updates, Campaign Monitor has continued to improve its email editor and template system. I have also used its newer personalization features and improved analytics, which help refine campaigns based on subscriber engagement. While automation has improved over time, it still feels secondary to campaign creation and design.

Feature Highlights

• High-quality email templates and visual editor
• Simple automation journeys for basic workflows
• Personalization based on subscriber data
• Clear reporting on engagement and campaign performance
• Strong focus on brand consistency and design

Campaign Monitor works best for teams that care deeply about how their emails look and feel. I have found it especially useful for agencies, designers, and brands that run polished campaigns but do not need complex automation logic.

Automation depth is limited. Once workflows require advanced branching, behavioral triggers, or tight CRM integration, Campaign Monitor can feel restrictive.

Based on my experience, Campaign Monitor is a good fit if your priority is beautifully designed email campaigns with light automation. If design comes first and automation is secondary, it does its job well.

13. Benchmark Email

I have used Benchmark Email for projects where simplicity was the main requirement and advanced automation was not a priority. It is a straightforward platform that focuses on helping users send clean campaigns and set up very basic workflows without friction.

Benchmark’s automation tools are limited but easy to understand. I have used it for welcome emails, basic drip sequences, and time-based follow-ups. The interface is simple, and it does not take long to get a campaign live, which can be useful when speed matters more than flexibility.

In more recent updates, Benchmark Email has added AI-assisted email writing tools and improved its email editor. These features help speed up content creation, especially for users who want guidance when drafting campaigns. While automation has seen minor improvements, the platform still prioritizes simplicity over depth.

Feature Highlights

• Easy-to-use email editor and templates
• Basic automation for simple workflows
• AI-assisted email content creation
• Clean interface with minimal setup
• Free plan for small lists

Benchmark Email works best for individuals and small businesses that want to send campaigns and run simple automated sequences without dealing with complex logic. I have found it useful for basic communication and list engagement.

Automation capabilities are very limited. Advanced segmentation, behavioral triggers, and multi-step branching workflows are not its strengths.

Based on my experience, Benchmark Email is a reasonable option if you need simple email marketing with light automation. It is not designed for sophisticated automation strategies.

14. OptinMonster

While OptinMonster is not an email marketing platform, I have used it alongside nearly every tool in this guide. In practice, email automation only performs as well as the leads entering the system, and that is where OptinMonster consistently adds value.

I use OptinMonster to capture leads through popups, slide-ins, floating bars, and embedded forms, then pass those leads directly into email platforms like ActiveCampaign, HubSpot, and Klaviyo. The targeting and trigger options make it possible to show the right offer based on behavior, referral source, device type, or exit intent, which improves lead quality before automation even begins.

Recent updates have expanded OptinMonster’s targeting rules, templates, and integrations. I have used it to segment leads at the point of capture, apply tags automatically, and route subscribers into specific automation paths inside my email platform. This reduces cleanup later and makes automation more effective from the start.

Feature Highlights

• Advanced lead capture and conversion targeting
• Seamless integrations with major email platforms
• Behavior-based triggers like exit intent and scroll depth
• Automatic tagging and segmentation at signup
• Easy setup with prebuilt templates

OptinMonster works best as the front end of an email automation system. I have found it especially useful for improving conversion rates and feeding higher-quality leads into automated workflows.

OptinMonster does not send emails or manage automations on its own. It works best when paired with a dedicated email marketing platform.

Based on my experience, OptinMonster is a strong addition to any email automation stack. If you want your automations to start with better leads and clearer intent, it plays a critical supporting role.

Final Thoughts..

After using and testing these tools across different projects, one thing is clear. There is no single best email automation platform for everyone.

Some tools excel at advanced, behavior-driven automation. Others prioritize simplicity, design, or ecommerce performance. The right choice depends on how complex your workflows are, how closely email needs to connect with sales or revenue data, and how much control you actually need.

What matters most is choosing a platform that fits how you work today and can still support you as your needs grow. Advanced automation is only valuable if it is used well, and simple tools often outperform complex ones when they match the use case.

No matter which platform you choose, automation starts before the first email is sent. Capturing the right leads and sending them into the right workflows makes a measurable difference. That is why I consistently pair these tools with OptinMonster to improve conversions and feed cleaner data into automation from the start.

If you’re interested in getting started with just one, it should definitely be OptinMonster. It has everything sales teams need to capture targeted leads and segment them right into your automated campaign. Sign up for OptinMonster today!

Here is the hard truth about the agency landscape in 2026: Your clients don’t care about the software. They care about the result.

If you are still operating on the old model—reselling an Email Service Provider (ESP) for a small markup—you are fighting a losing battle against commodity pricing. To scale a profitable agency today, you must shift from selling “access to tools” to selling “Growth as a Service.”

You don’t just need a white-label tool; you need a Growth Stack.

• The Engine: Reliable infrastructure to deliver the message (The ESP).
• The Fuel: An automated system to capture high-intent leads (OptinMonster).
• The Proof: Reporting that connects the dots between emails sent and dollars made.

We’ve audited the top white label email marketing softwares to help you build the ultimate white-label stack that protects your margins and makes your agency indispensable.

The Agency Shift: Why “Just Sending Emails” Fails

Before we dive into the tools, we need to address why the “old way” of white labeling is dead. The digital environment has shifted, and your service offering needs to adapt to three critical trends:

1. The Rise of the “Intelligent Inbox”

Gmail and Apple Mail no longer just filter spam; they filter boredom. In 2026, inbox algorithms prioritize “Engagement Signals”—scroll depth, replies, and forwards—to determine if your client’s email lands in the Primary tab or the Promo purgatory.

• The Agency Fix: You can’t just send blasts. You need tools that support BIMI (Brand Indicators for Message Identification) to verify your client’s domain and display their logo, instantly building trust.

2. The Zero-Party Data Requirement

Third-party cookies are history. Clients are looking to you to help them own their data.

• The Agency Fix: Your stack must include a way to collect Zero-Party Data—information a user voluntarily gives you (like “I’m interested in Men’s Hiking Gear”). This requires more than a sidebar form; it requires intelligent, interactive lead capture.

3. The “Outcome” Economy

Agencies are moving away from billing for hours and toward billing for outcomes.

• The Agency Fix: Don’t sell a “Mailchimp alternative.” Sell a “Revenue Engine.” By bundling a high-volume sender (like BigMailer) with a high-conversion lead tool (like OptinMonster), you create a proprietary service that clients can’t easily replace.

Layer 1: The “Engines” (Top White Label ESPs)

This is the foundation of your stack. You need an engine that is invisible to your client but indispensable to their revenue.

When choosing an Email Service Provider (ESP) to white label, ignore the generic “features list.” As an agency, your priority is margin protection and scalability. You need a tool that allows you to manage 50+ client accounts from one login without eating into your profits.

Here are the 4 best “Engines” or white label email marketing software to power your agency in 2026.

1. BigMailer.io – Best for High Volume & Margins

If your agency manages franchises or high-volume senders, BigMailer is your margin-protector. Unlike most ESPs that punish you for growth, BigMailer is built on a flat-rate model.

• The Agency Pitch: “We provide enterprise-grade infrastructure without the enterprise price tag.”
• Why It Wins: It supports unlimited sub-accounts and brands under a single agency dashboard. You can connect Amazon SES (Simple Email Service) to send millions of emails for pennies, allowing you to charge clients a premium “management fee” while keeping your hard costs incredibly low.
• White Label Features:
  • Full custom domain mapping (e.g., marketing.youragency.com).
  • Role-based access so clients only see what you want them to see.
  • RSS-to-email automation for effortless newsletters.

Pro-Tip: Use BigMailer’s “Brand Management” view to monitor deliverability across all your clients in real-time. If one client hits a spam trap, you can isolate it immediately without affecting your other accounts.

2. ActiveCampaign – Best for “Marketing-as-a-Service”

ActiveCampaign isn’t just an email tool; it’s a Customer Experience Automation (CXA) platform. This is the tool you choose when you want to sell high-ticket “Implementation Retainers.”

• The Agency Pitch: “We don’t just send newsletters; we build automated sales machines that run 24/7.”
• Why It Wins: The library of 900+ pre-made automation recipes allows your team to deploy complex workflows (like “Abandoned Cart” or “Re-Engagement”) in minutes, not days. You bill for the strategy, not the setup time.
• White Label Features:
  • Enterprise Tier: Fully rebrandable HTML/CSS interface.
  • Custom Domains: Remove all “ActiveCampaign” references from links and login pages.
  • CRM Integration: Aligns your client’s sales and marketing teams, proving your ROI.

3. Brevo (formerly Sendinblue) – Best for SMBs & Omnichannel

Brevo is the “Swiss Army Knife” for agencies serving Small to Mid-sized Businesses (SMBs). It disrupts the market with a pricing model based on emails sent, not list size.

• The Agency Pitch: “Grow your list as big as you want—you only pay when you push ‘Send’.”
• Why It Wins: It covers the entire customer journey: Email, SMS, WhatsApp, and Chat. This allows you to upsell “Omnichannel Marketing Packages” to clients who only came in for email.
• AI Advantage: Brevo’s “Aura” AI assistant automatically generates subject lines and optimizes send times, drastically reducing your team’s copywriting workload.
• White Label Features:
  • Agency dashboard to manage all sub-accounts from one wallet.
  • White-label editor to let clients build their own campaigns (if you allow it).

4. Mailgun – Best for Transactional & Developer-Heavy Agencies

If your agency builds custom apps or manages critical transactional email (password resets, order receipts), Mailgun is the industry standard. It is the “plumber” of the internet—not pretty, but incredibly robust.

• The Agency Pitch: “We guarantee your critical emails hit the inbox, not the spam folder.”
• Why It Wins: It offers granular IP White Labeling. You can assign dedicated IPs to specific clients to protect their reputation (and yours).
• White Label Features:
  • Sub-account isolation: Complete separation of data and reputation between clients.
  • Inbox Placement Testing: Predict exactly where an email will land before you send it.

Expert Note: A Ferrari engine is useless without gas. These ESPs are powerful, but they cannot generate their own leads.

That is where the second layer of your stack comes in. You need a dedicated “Fuel” source to feed these engines with high-quality, segmented leads.

Layer 2: The “Fuel” (List Growth & CRO)

An engine without fuel is just a heavy, expensive paperweight.

The biggest mistake agencies make is selling an ESP (like ActiveCampaign) without selling a way to fill it. If your client has 500 subscribers and adds 5 per month, they will fire you in 90 days because “email marketing doesn’t work.”

You need a tool that guarantees list growth.

5. OptinMonster – The Agency Revenue Engine

Best For: Agencies selling “Conversion Optimization” and “List Growth” retainers.

Most tools on this list cost you money. OptinMonster is the only one that makes you money. It bridges the gap between traffic and the ESP, turning anonymous visitors into segmented leads.

• The Agency Pitch: “We don’t just manage your email list; we double it. We use behavioral intelligence to capture leads that your competitors are ignoring.”
• Why It Wins: It solves the “Empty Room” problem. By layering OptinMonster on top of BigMailer or Brevo, you control the entire data pipeline.
• Strategy (Zero-Party Data): With third-party cookies dead, you must collect data directly. Use OptinMonster’s Campaigns to ask specific questions (e.g., “Are you looking for Men’s or Women’s hiking gear?”). This “Zero-Party Data” is instantly tagged and pushed to your ESP, triggering hyper-personalized flows.

The White Label “Superpower”: OptinMonster offers a suite of features specifically designed to make you look like the tech wizard:

1. Custom Branding: Replace the OptinMonster logo with your agency’s logo in the dashboard. When clients log in to check their lead stats, they see your brand, reinforcing your value.
2. Sub-Accounts: Give clients granular access. You can let them view their analytics without giving them the keys to break the campaign settings.
3. Agency Playbooks: You don’t need to reinvent the wheel. Import high-converting templates across all your client sites in one click.

Expert Note: Stop charging for “Popups.” Charge for “CRO as a Service.”

The Model: You pay for the OptinMonster Agency license. You charge the client a $500–$1,500/month retainer to design, A/B test, and optimize their lead capture strategy. Your margin is nearly 100% after the software cost.

Layer 3: The “Proof” (Reporting & Maintenance)

If you don’t report it, it didn’t happen; clients expect transparency. These utilities protect your retainer by proving your worth.

6. Reporting Ninja – Best for Client Retention

Best For: Automated, cross-channel reporting.

Agencies lose clients when they fail to communicate value. Reporting Ninja solves this by automating the “Monthly Report” that clients actually read.

• White Label Features: Fully branded portals and PDF exports. You can host the report dashboard on your own domain (e.g., reports.youragency.com).
• Why It Wins: It pulls data from Google Analytics 4, Facebook Ads, and your email platform into one view, showing the client the full picture of how your email strategy influenced their total revenue.

7. Warmy.io – Best for Deliverability Assurance

The average email open rate is around 17%, but you can push it up to 30% by following best email practices. This is especially important if you’re writing cold email subject lines for sales prospecting, which usually has a lower open rate.

In this post, we’ll talk about everything you need to know about writing catchy sales email subject lines.

Let’s get started.

• 7 Qualities That a Good Sales Email Subject Line Should Have
• Best Email Subject Lines for Cold Emails
• Best Email Subject Lines for Requesting Meetings with Prospects
• Best Subject Lines for Follow-up Emails
• Best Referral Email Subject Lines
• Best Email Subject Lines If You Don’t Get Any Response

What Makes a Good Email Subject Line for Sales?

Before we start writing catchy email subject lines for sales, we should understand what makes a subject line good.

Famous copywriter Eugene Schwartz said:

“Your headline has one job: to stop your prospect and compel him to read the second sentence of your ad.”

The same best practices apply to email subject lines.

Good sales email subject lines should stop prospects in their tracks and compel them to open your email.

That’s why all the best sales email subject lines have one or more of these 7 qualities:

1. It Should Be Brief

Subject lines that are too long have many disadvantages:

• They’re difficult to read and understand
• They’re likely to lose your reader’s attention
• They’re likely to get cut off on smaller mobile devices

Therefore, when writing that perfect sales email subject line, think of the limitations caused by smaller mobile devices.

Generally, a 60-character email subject line should work fine on desktops. But you should keep it less than 40 characters to make sure it appears perfectly fine on all types of screens.

2. It Should Be Personalized

Personalized subject lines can get up to 50% higher open rates.

Don’t just send bulk emails to everyone without personalizing them first. Spend a little time customizing them. Personalized emails are more likely to capture the attention of prospective customers.

Here are a few tips to help you create personalized subject lines:

• Include the recipient’s first name
• Mention their interests
• Send them emails on their birthdays and anniversaries
• Talk about their transaction history with your business
• Add some personality. It can make for a more compelling subject line.
• Write as if you’re talking to a friend
• Use emojis to stand out

3. It Should Create Urgency

A sense of urgency in your email subject line can motivate prospects to click on it. Otherwise, they might put that email aside for later, and you will miss an opportunity.

Making your subject line seem time-sensitive is an effective tool to draw attention and increase the open rate. However, it should be handled carefully and sparingly. If you overdo it, you risk annoying your recipients with all these urgent requests. They may even mark your email as spam, which can negatively affect your email deliverability rate.

4. It Should Be Interesting

Why would anyone click on anything that’s not interesting, right?

• Share an interesting tidbit about their industry
• Share recent news that the recipient should know
• Ask a question that might interest them
• Ask for their help

There are many ways to make your email subject line interesting, as we’ll see later in this article. No matter how unique and useful your email is, they will never find it if they don’t open your email.

That’s why putting your energy into crafting that exciting subject line is the key. It’s especially important for cold email subject lines, where the recipients don’t yet know how awesome your emails are.

5. It Should Have the Right Keywords

Many internet users filter their emails by keywords. Certain words can also grab the prospect’s attention.

Therefore, your email subject line should have the right keywords. Unfortunately, there is no way to find out what the right keywords are.

We recommend running A/B tests for email subject lines to try out different combinations of keywords. Find the ones that resonate the most with your target audience.

It’s also important to keep a log of everything you do and measure the performance of each variation of the subject line.

Over time, you’ll have enough data to identify the right keywords for the right audience groups.

6. It Should Increase Curiosity

“Curiosity is the essence of human existence.” – Gene Cernan.

You’re more likely to act if something intrigues you and raises your curiosity. The same principles can be applied to your sales email subject lines.

However, it’s important to fully understand your buyer persona first. You can’t successfully make them curious if you don’t know who they’re and what they really want.

For instance, Duolingo is an app that helps people learn different languages. Duolingo’s unique selling point is that it can help busy people learn 30+ languages, even if they spend only a few minutes daily.

Now, look at this subject line.

It’s short, to the point, increases curiosity, and understands what its audience wants.

7. It Should Offer Value

Last but not least, your email should offer a lot of value to people. And that value should reflect in the subject line.

• Does your business make a product or service the reader has been looking for?
• Do you have a fantastic discount offer that is too tempting to refuse?
• Do you have a piece of information that can change their life?

Identify the most valuable thing to your readers and put that in the subject line.

Now you know the 7 qualities a great subject line should have. Now it’s time to see some cool sales email subject line examples you can use.

Best Cold Email Subject Lines

Writing cold email subject lines can be really tough because the recipient of the email may not even know you. There is no established connection to leverage, and your email is more likely to be seen as spammy.

Here are a few proven cold email subject line examples to help you make a great first impression and kickstart your email campaign in the best possible way.

1. “Hi, [name].”

Sometimes, that’s all you need. A short subject line with a friendly hello and your prospect’s name.

It creates an element of curiosity and personalization that can help you increase your open rate. A simple, friendly email like this can even stand out in dozens of emails that rely on cleverness and creativity.

2. “Nice to meet you, [name].”

You can also add warmth by replacing “Hi” with a “nice to meet you.”

This works well if they just downloaded or bought something from you, and you’re reaching out to them for the first time.

3. “Hi [prospect’s name], [question]?”

If a simple hello isn’t your vibe, how about posing a question?

Questions provoke answers, which can spark conversations. Subject lines with questions are also more likely to invoke curiosity.

However, make sure the question is relevant and exciting to the reader.

4. “Question about [subject].”

Another way to pose a question is to not put it in the subject line. Instead, use it as a teaser to encourage them to open your email.

Only mention the subject or topic of the question. And that might interest readers enough to open your email to find out what the question is.

5. “Question about [goal].”

If you understand your audience, their motivations, and their goals, this can be an effective cold sales email subject line.

It’s everyone’s aim to reach their goals quickly and easily. Asking them about their goals and hinting at potential solutions might get you in the door.

6. “Fix your [pain point/problem] in [time].”

Or, if that doesn’t work, you can be more specific.

This cold email subject line has many good qualities:

• It starts with an action verb
• It specifically addresses the pain point or problem that the reader is facing
• It promises to help solve that problem in a specific period.

That’s usually enough to get them interested in what you have to say.

7. “[Your company name] x [Prospect’s company name].”

If your company is recognizable, this can be an effective way to grab your reader’s attention. Put your company name with their company name in the email subject line and trigger their curiosity.

8. “Don’t open this email.”

Reverse psychology for the win.

Just make sure this is in line with the tone and style of the rest of your email. Also, your email must have a nice payoff if you decide to use this subject line.

Or your email may be considered clickbait by some.

9. “Are you a part of the [X%]?”

The X%, in this case, could be anything: people who are your customers benefiting from your services or people who aren’t your customers and, therefore, missing out on something cool.

This cold email subject line increases curiosity by suggesting there is an exclusive group of people.

10. “Hey [name], I loved your [something].”

Use this cold email subject line if you have a connection to leverage.

For example, you can use this email subject line and highlight a blog post if you’re reaching out to a blogger to build backlinks.

11. “Only the best for you, [prospect’s name].”

This subject line not only piques curiosity but also implies there’s value for recipients. It also has a sense of personalization and familiarity that can increase open rates.

12. “Tonight.”

Keep things mysterious and interesting with this short subject line. It’s well suited for flash discount offers.

Although it may seem odd, don’t underestimate how well these short subject lines can do.

13. “[Day and time].”

Increase the recipient’s curiosity by only mentioning the day and time in the subject line. That day and time could be for an upcoming event, a limited-time discount offer, or a meeting request.

The only way to find out is to open the email.

14. “One day left.”

If you have a limited-time offer, you can use this subject line to create a sense of urgency.

We recommend using a tried and tested call-to-action in the email copy to maximize your sales and revenue if the recipients decide to act.

15. “This will only take [X] seconds.”

Cold emails can often be a waste of time for the readers. That’s why a lot of people don’t even open them.

However, you can minimize some of that concern by putting the exact time it takes to read your email and take action. For example, “This will only take 23 seconds.”

Here are a few tips to make this work:

• Use seconds, not minutes.
• Keep the count as low as possible.
• Keep the rest of your email short and to the point.

Best Email Subject Lines for Meeting Requests

You will want to schedule a meeting with a prospect at some point in the sales process. It’s a good idea to be direct and clear about it when that time comes.

Here are a few email subject lines you can use to request meetings with prospects.

16. “Hey, [name]. Can we meet for 10 mins this week?”

You can deliver a low-pressure opportunity for a casual meeting with this subject line. Most sales reps aim for 30- to 60-minute meetings, which can be a big commitment for your prospects.

However, a 10-minute conversation is easier to manage. That’s why conveying your intentions right in the subject line is important.

17. “[Name], are you free this week?”

Or you can use this subject line if a 10-minute meet-up doesn’t work for you.

Remember, it’s still better than mentioning a 60-minute meeting in the subject line.

18. “Meeting invite for [day]?”

Being specific can sometimes help you land more opportunities. If “this week” is too vague and not producing the right results for you, try aiming for a specific day.

19. “Hey, [name]. Are you available [day and time]?”

If specificity works better in your industry, you can propose a meeting on a specific day and time in the email subject line.

However, it may not work unless you have discussed this prior with the prospect.

20. “Time to chat?”

Casual, friendly, no pressure.

21. “[Name], you’re invited!”

It usually works well if you want to invite a prospect to an event, expo, or trade show. Make sure to add all the details they may need to know.

This includes information on where and how to find your business, contact information, and details about the event.

22. “Hey [name]! Remember me?”

Did you ever meet a prospect at an industry event, exchange information, but lose touch?

This simple, friendly, casual subject line is an excellent way for a sales team to reestablish that connection.

Pro tip: Include a photo of the event at which you met the prospect. It may help jog the memory and even serve as an ice-breaker.

Best Follow-up Email Subject Lines

After the first conversation or sales meeting with your prospects, it’s time to follow up with emails. You can also send follow-up emails if you think you’re losing your customers or if they haven’t responded to you in a while.

Here are a few subject line examples that you can use to follow up.

23. “Hey, [name]. Here are the resources I promised.”

It’s common in sales meetings to exchange resources after the call. In that case, this straightforward subject line is perfect.

24. “Hey, [name]. I’d love your feedback.”

Use this follow-up email subject line if you want to run something by your sales prospect. This works especially well if you share the first draft of a proposal or a plan with a potential client.

25. “Our next steps.”

It’s standard practice to share notes and the next action items after a meeting. In that case, this simple yet obvious email line can work just fine.

Make sure to add detailed action items in the email.

26. “Hey, [name]. It’s been a while.”

Follow up with this email subject line if you haven’t been able to get in touch with a prospect for a long time.

This follow-up email subject line is warm, friendly, and invites the reader to resume the conversation.

27. “Do you have any questions?”

This follow-up subject line for sales emails is perfect if you lost touch with a prospect after meeting with them once or twice.

Reach out to them and ask if they have any questions they’d like to get answered. Sometimes, a prospect looks at multiple options as they meet different salespeople from other businesses.

Reaching out to them with this subject line may remind them of your meeting and spark a conversation if they have questions.

28. “Before you decide…”

If you feel you’re losing a sales prospect, use this subject line for outreach. This is the perfect opportunity to share customer testimonials, reviews, and case studies to put their minds at ease.

Best Referral Sales Subject Lines

Referrals are the bread and butter for salespeople. Use one of these referral sales subject lines if you’re contacting a prospect for the first time.

29. “[Mutual connection’s name] suggested I reach out.”

Start with the mutual connection’s name to build connection and credibility right out of the gate. Seeing a familiar name in the inbox may also help capture the reader’s attention and increase the open rate.

30. “[Mutual connection’s name] helped me find you.”

This is a more informal or casual version of the previous subject line. Depending on your target audience, this more relaxed version might be a better fit for you.

31. “[Mutual connection’s name] thinks you’ll love us too.”

This is another variation of the same referral sales email subject line, but it has the most personality.

This subject line pairs well with data and case studies. So include white papers, case studies, and customer testimonials that show exactly how you helped the people who referred you.

32. “I found you through [referral’s name].”

Use this referral sales subject line if you’re in a more formal setting.

You can also use this subject line for A/B testing and see how much the open rate changes by moving the referral’s name to the end of the subject line.

Best Email Subject Lines After No Response

Sometimes, a trail goes cold. Use one of these subject lines to improve response rates.

33. “[Name]?”

It can’t be simpler than this, can it?

Apart from showing concern, this email subject line also creates curiosity and mystery. What could be the contents of this email? Only one way for the reader to find out.

34. “RE: [prospect’s last email].”

This is a tried and tested sales email subject line if you didn’t get a second response from your prospect.

The trick is to present your email as a part of a previous, ongoing conversation. The reader is more likely to click and respond to it even if they have ignored your other messages.

35. “Permission to close your file.”

This sales email subject line relies on the fear of missing out (FOMO).

You can motivate sales prospects to take action by asking permission to close their file. This email implies that you won’t contact them in the future; this is their last chance.

A combination of uncertainty, FOMO and urgency can help increase the open rate.

36. “Hey [name], we just launched [feature].”

This is an excellent way to get your foot in the door again. Mention a new product feature or announcement in the subject line to grab your reader’s attention.

However, you must fully understand your target audience for this to work. Know their pain points and add the announcement that’d mean most to them.

37. “Did you see [news]?”

You can also use a recent news piece in the email’s subject line to create the same effect. This subject line is helpful if you don’t have any product-related announcements to make.

Make sure to add all the necessary information about the news, its effects on the reader, and how you can help them.

38. “Am I assuming correctly?”

Perhaps it’s time to move on if a prospect has been ignoring you for a long time. But don’t give up before giving it one last shot.

Double-check with your sales prospects using this email subject line. It’s slightly mysterious, creates curiosity, and can make them open your email.

39. “If you change your mind about partnering with [your company name].”

Unlink the previous subject line, this one paves the way for another chance in the future.

Put the ball in your prospect’s court by giving them all the information they may need to contact you again. Mention all the things you can do for them clearly and concisely. Bonus points if you can share relevant case studies, whitepapers, customer testimonials, and results you produced for other clients.

40. “Should I stay or should I go?”

There’s nothing that a Clash song can’t fix, right?

Craft a clever email using this pop culture reference as the subject line and give it a last shot.

Craft the Best Sales Email Subject Lines

Email Marketing Metrics vs. Email Marketing KPIs

Before we go any further, let’s explain “What are email marketing metrics?”

“Metric” means measurement. In this case, you’re measuring how your customers interact with your email marketing campaigns. Metrics are data points about how your business processes are running.

Another term you’ll hear a lot is KPI. KPI stands for key performance indicator. These are measurements of progress toward your strategic business goals. Every KPI includes metrics, but not every metric is a KPI.

For example, a KPI for your email marketing might be to increase sales revenue. To achieve this goal, you might track several metrics, such as open rate, click-through rate, conversion rate, and revenue generated from the email campaign.

By tracking these metrics together, you can see how well you’re doing in reaching your overall goal of increasing sales revenue and make changes to your strategy if needed.

In this article, we’ll be defining the most important metrics for email marketing. How you combine or leverage these metrics toward your email marketing KPIs is up to you.

17 Essential Metrics for Email Marketing

As we go through the different metrics for email marketing, remember that there are several ways to measure performance. You can look at your metrics over a certain time period, or look at the metrics on an individual email campaign.

Try not to fixate too much on how a single email campaign performs. It’s more important to look at patterns over time, as well as the overall context of your digital marketing.

With that being said, let’s take a look at the top email performance metrics you need to know.

Email Open Rate

Open rate is how many people actually open the email that you send to them.

If you sent a marketing email to 100 subscribers, and 50 of them opened the email, your open rate would be 50%.

Generally speaking, the higher your open rates, the more successful your email marketing efforts will be. But open rate isn’t always easy to measure, so this metric can sometimes be deceiving.

Open rate is typically tracked using a tiny image. When that image is loaded in an email client, that counts as an open. But if the recipient opens the email with images turned off, that won’t get counted.

Furthermore, just because someone opens an email doesn’t mean they read it. So let’s look at some other email marketing metrics that can give you better insight.

Clickthrough Rate

Your clickthrough rate (CTR) is how many subscribers click on any links you’ve included in your email.

If you sent an email to 100 subscribers, and 27 of them clicked on the call-to-action (CTA) button, your clickthrough rate would be 27%.

Someone who clicks a link in your email probably read at least some of the content. This means that they are more engaged than someone who didn’t click anything.

Just like open rates, clickthrough rates require some interpretation. Someone clicking the same link multiple times or from multiple devices may cause your clickthrough rate to be artificially high. Some email service providers measure total clickthrough rate as well as unique clickthrough rate.

Click-to-Open Rate

Click-to-open rate (CTOR) is the ratio of clicks to email opens. It only measures clicks from the emails that were opened, and therefore gives a more accurate picture of email engagement than clickthrough rate alone.

For example, imagine you sent emails to 100 subscribers. 50 of them opened the message, and 10 of them clicked a link. If you were measuring clickthrough rate, it would be 10 clicks divided by the total number of emails sent, or 10%. But the click-to-open rate would be 10 clicks divided by 50 unique opens, or 20%.

A high CTOR indicates that your email was successful in two ways. First, you convinced people to open the email. Second, you persuaded them to take the desired action of clicking the link to your sales page, social media page, or other URL.

List Growth Rate

The list growth rate is a measure of how well your email acquisition efforts are doing. A high list growth rate means that you’re attracting lots of new subscribers to your email list. A low list growth rate might mean that your lead magnets or optin forms need to be improved.

You can calculate list growth rate by taking the number of new subscribers in a set time period and dividing it by the total number of subscribers at the start of that time period.

For instance, if you start the month with 1,000 subscribers, and at the end of the month you added 100 new subscribers, your list growth rate would be 10%.

Sharing Rate

The sharing rate is a metric that measures how often subscribers are sharing your emails with others. It’s a way to see how viral your emails are and how effectively you’re tapping into your subscribers’ networks.

The sharing rate is calculated by dividing the number of times your emails were shared by the number of times they were opened. So, it’s a measure of how many people who opened your email went on to share it with others.

For example, if you sent an email to 100 people, 50 of them opened the email, and 10 of them shared it, your sharing rate would be 20%. This means that 20% of the people who opened the email went on to share it with others.

A high sharing rate indicates that your emails are resonating with your subscribers and that they’re eager to share them with their friends and colleagues. This can be a powerful way to expand your reach and bring new subscribers to your email list. However, it’s worth noting that not all emails are well-suited to being shared, so a low sharing rate is not necessarily a sign of an ineffective email marketing campaign.

Forwarding Rate

Forwarding rate is how often your subscribers forward your emails to someone else. It’s similar to sharing rate in that it measures how interesting your content is and how well you’re connecting to your subscriber networks.

You can calculate your forwarding rate by taking the number of email forwards and dividing it by the number of email opens. Not every ESP tracks forwarding or shares automatically. You may need to use unique URLs, special forwarding forms, or social sharing buttons to track these “shareability” metrics.

Conversion Rate

Now let’s dig deeper into email marketing metrics related to conversions. Email conversion rate measures how many people take a specific action after receiving your marketing email. That action might be following you on social media, reading a blog post, visiting a sales page, or making a purchase.

For example, if you emailed 1,000 subscribers and 89 of them clicked a link to your sales page, your conversion rate would be 8.9%. But if the conversion you’re measuring is actual sales rather than clicks, your conversion rate would likely be lower since not everyone who sees your sales page ends up making a purchase.

As you might guess from the definition, conversion rate can be tricky to calculate. Many factors can influence your conversion rate, starting with the desired action you’re asking people to take and ranging from the subject line to the email design.

Revenue Per Email

Revenue per email is simply how much money you generate from each email sent. It’s a way to see how effectively your email marketing campaigns are driving revenue for your business.

Revenue per email is calculated by dividing the total revenue generated from your email marketing campaign by the number of emails sent. This number is then expressed in monetary terms, such as dollars or euros.

For instance, if you sent an email to 100 people and generated $500 in revenue from that email, your RPE would be $5.

The higher your RPE, the more successful your emails are. But like all metrics, RPE can be distorted by any number of factors. For example, if you have a very high ticket offer that’s only marketed to a few VIP subscribers, your RPE might look extremely high without accounting for the rest of your email list that isn’t buying much.

That’s why it’s important to connect your metrics to specific email marketing KPIs.

Revenue Per Subscriber

Revenue per subscriber (RPS) is how much revenue you’re generating for each subscriber on your list. You calculate it by taking the total amount of revenue from a campaign and dividing it by the number of subscribers who received that campaign.

If you sent a promotional email to 100 subscribers and generated $5,000 in revenue, your RPS would be $50 per subscriber.

RPS is a way to measure how valuable each individual subscriber is to your bottom line. Keep in mind that RPS is an average of subscribers who buy nothing and subscribers who buy a lot.

Subscriber Lifetime Value

Subscriber lifetime value is an estimate of how much an individual subscriber is likely to contribute to your revenue over the course of their subscription period. This is an approximate average rather than an actual number.

To find your subscriber lifetime value, take the average revenue per email and multiply it by the total number of emails you expect to send to a subscriber. Not every email you send will have a high RPE, which is why you need to take an average.

For example, if you expect to send an average of 10 emails per year to a subscriber and you generate an average of $10 in revenue from each email, your subscriber lifetime value would be $100.

To calculate how profitable each subscriber is for your business, you would subtract the subscriber acquisition cost, which we explain below, from the subscriber lifetime value.

Subscriber Acquisition Cost

Subscriber acquisition cost is the average money spent to bring in a new subscriber. This might include buying ad campaigns, paying marketing staff to set up optin forms, or creating content that drives search traffic which converts to subscribers.

For example, if you spent $1,000 on list-building ads and acquired 100 new subscribers, your subscriber acquisition cost would be $10. If your subscriber lifetime value was $100, then your profit per subscriber would be $90.

Return on Investment (ROI)

Email marketing ROI, or return on investment, measures the profitability of your email marketing efforts. It’s a way to see how much money you’re making from your email marketing campaigns compared to how much money you’re spending on them.

You can calculate email marketing ROI by dividing the total revenue generated from your email marketing campaigns by the total cost of those campaigns. This number is then expressed as a percentage.

For example, if you spent $1,000 on email marketing campaigns and generated $5,000 in revenue from those campaigns, your email marketing ROI would be 500%. This means that you made $5 for every $1 you spent on email marketing.

Email marketing often has the highest ROI of all digital marketing channels. You can improve your ROI by increasing your revenue, decreasing your costs, or some combination of both.

Email Bounce Rate

Email bounce rate is the number of emails that are returned to the sender as undeliverable.

There are two types of email bounces: hard bounces and soft bounces. Hard bounces occur when an email is returned to the sender because the recipient’s email address is invalid or no longer exists. Soft bounces occur when an email is returned to the sender because of a temporary issue with the recipient’s email server, such as a full inbox or a server outage.

Email bounce rate is calculated by dividing the number of bounced emails by the total number of emails sent. This number is then expressed as a percentage.

For example, if you sent 100 emails and 2 of them bounced, your email bounce rate would be 2%. This means that 2% of your emails failed to reach their intended recipient.

There can be many reasons for a high bounce rate, including a low-quality subscriber list, outdated email addresses, or technical issues with your email server. To minimize your email bounce rate, it’s important to regularly clean and update your email list, and to monitor and address any technical issues with your email campaigns.

Unsubscribe Rate

The unsubscribe rate is the number of people who leave your email list in a certain time period. You calculate the unsubscribe rate by dividing the number of unsubscribes by the total number of subscribers.

People unsubscribe for many reasons, some of which are under your control and some of which aren’t. A high unsubscribe rate can indicate that your email campaigns are not providing value to your subscribers, or that your email content is irrelevant, repetitive, or too frequent. But sometimes people just lose interest or decide they’re getting too many emails.

To reduce your unsubscribe rate, it’s important to continually test and optimize your email campaigns to find the most interesting and relevant content for your subscribers. You can also give your subscribers more control over the frequency and type of emails they receive, which can help reduce unsubscribes. Another strategy is to use a double optin to ensure that new subscribers are actually interested in receiving your content and not just trying to get a freebie.

Spam Complaints

This metric is the number of people who mark your emails as spam. When someone sends your emails to the spam folder, that’s a sign that they do not want to receive any more emails from you. This is likely because they don’t believe that your emails are delivering any value.

Spam complaints can seriously affect your sender reputation. A very high spam complaint rate can prevent your emails from being delivered even to legitimate email recipients.

To minimize your spam complaint rate, it’s important to follow best practices for email marketing. Always make sure you get clear consent to add subscribers to your list and send marketing emails. Take the time to create valuable content that subscribers actually want to read.

Additionally, make it easy to unsubscribe or manage their email subscription. When subscribers can’t find the unsubscribe link, many will resort to making a spam report. This is much worse for your sender reputation and email deliverability than a few unsubscribes.

Email Deliverability Rate

Email deliverability rate is the percentage of emails that successfully reach the intended inbox.

You can calculate email deliverability by dividing the number of successfully delivered emails by the total number of emails sent.

The higher your email deliverability rate, the more effective your email marketing strategy will be. A decreasing email deliverability rate can become a self-fulfilling prophecy, as high spam complaints and deliverability issues can signal to Internet service providers (ISPs) that your email server is unreliable or possibly dangerous. That’s why it’s important to monitor your email deliverability rate and take steps to address any issues that are affecting it.

You can use tools like Mailgenius and Mail Tester to test out your deliverability.

Email Client and Device Usage

Finally, it’s worth noting that each of these metrics we’ve listed may look different on desktop compared to mobile devices.

More people than ever are browsing from their smartphones. If you know which apps or device types your subscribers are using, you can optimize your email campaigns accordingly.

How to Improve Your Email Marketing KPIs

Each of these email marketing metrics on their own may not mean very much. But put together, your email marketing KPIs can show you whether your business is healthy or in trouble.

One of the best ways to improve your email marketing metrics and KPIs is to improve your lead quality. This means qualifying new leads so that you’re sending emails to people who are actually interested in what you have to say. Here are a few ways to do that with OptinMonster:

Page-level targeting: With OptinMonster, you can easily target your lead generation forms to specific pages or post categories. If you have insight into which pages are most popular, you can offer lead magnets and optin forms that match those pages. For example, a visitor reading a cupcake recipe would probably be more interested in a checklist of party planning tips than an eBook on interior design. Check out how Paint Your Life grew their conversion rate to a whopping 28.57% using page-level targeting.

Field mapping for lead segmentation: In addition to targeting visitors by page or other browsing activity, you can add fields to your optin form. This allows new subscribers to tell you what they’re interested in, demographic information, how often they want to hear from you, and other important data. With this information, you can then send the right emails to the right subscribers. They’ll be more likely to open your emails, click your links, and even share your messages with friends.

2-step optins: Most of the time we want to reduce friction in the user experience. But 2-step optins can actually improve your email marketing metrics. Visitors who click “Yes” are more likely to continue the signup process, and be more interested in your email content. The same goes for double optin emails that new subscribers have to click on to confirm their subscription.

A/B testing: A/B testing, or split testing, is the practice of trying out different messaging and design elements to see what works best. You can split test email subject lines and copy, landing page design, CTA wording, and just about anything else you can think of. Most email marketing tools will let you A/B test subject lines, while more advanced A/B testing may require other tools.

Summary: What Are the Most Important Metrics for Email Marketing?

The most important email marketing metrics for your business depend on your goals. Your business goals may change over time and that’s perfectly fine. Just make sure you establish your own benchmarks for each metric so you know where you’re starting and where you need to be.

In general, we suggest that earlier stage businesses focus on engagement metrics, such as:

• Click-through rate
• Forwarding and sharing rates
• List growth rate

More advanced businesses with a healthy list can begin to optimize for revenue-related metrics like:

• Revenue Per Subscriber
• Subscriber Acquisition Cost
• Return on Investment (ROI)

And every business needs to be mindful of overall list health metrics, including:

• Bounce rate

The next step in newsletter marketing is to create and send your newsletter.

Newsletters are usually sent to broadcast lists that need to follow specific guidelines. For example, if you choose to send bulk email addresses from a personal email, it will get flagged as spam.

And once your email address gets blacklisted, even regular administration and client emails can be blocked.

To avoid this problem, you need to use an email service provider to make sure your emails go to your audience’s inbox and don’t go to the spam folder.

Which Is the Best WordPress Newsletter Plugin?

A WordPress newsletter plugin can significantly enhance your email marketing efforts. These plugins offer many features and benefits, from simplifying newsletter creation to automating campaigns and analyzing performance.

Additionally, pairing a reliable email subscription plugin with your newsletter plugin ensures a seamless user experience for your subscribers.

So, take advantage of these powerful tools, choose the best WordPress newsletter plugin for your needs, and start engaging with your audience through beautiful newsletters and compelling email campaigns.

Note: Professionals and experienced WordPress users choose not to use a newsletter plugin within WordPress for managing their email lists. The main reason for this is to avoid the inconvenience of integrating an SMTP plugin and connecting it with an email delivery service.

Want to know our verdict? To run a successful newsletter marketing campaign and drive results that actually grow your business, you need to use a handful of tools:

• OptinMonster – The one and only tool you need to collect leads
• Constant Contact – To create and send newsletters with high delivery rates

How to Choose the Best Blogging Platform?

Starting with the wrong platform can make it very difficult if you want to switch later on in the future. That’s why it’s important to consider carefully what you’re looking for in a blogging platform before you start.

Best Marketing Automation Tools at a Glance

Editor’s Choice: OptinMonster – Best for Lead Capture & Conversions
Before you can nurture leads with email or CRM workflows, you need to capture them. OptinMonster automates that critical first step with powerful on-site campaigns—popups, floating bars, gamified wheels, and more—that integrate directly with tools like HubSpot, Mailchimp, Brevo, and ActiveCampaign. Think of it as the spark that makes all your other automations more effective.

Running marketing without automation is like pouring water into a leaky bucket—you work hard to attract visitors, but too many slip away because you can’t follow up at the right time, on the right channel.

That’s where marketing automation tools come in. They take repetitive tasks off your plate, connect your campaigns across email, SMS, social, and more, and make sure every lead gets a personalized experience at scale. Instead of spending hours chasing down small tasks, you and your team can focus on strategy, storytelling, and growth.

But with so many platforms out there—from free tools for startups to enterprise-level solutions—it’s tough to know which one is right for your business. Some are great for small teams who just need email automation, while others are full-blown marketing suites that replace half your tech stack.

We’ve tested the most popular marketing automation tools available today, looking at ease of use, integrations, price-to-value, and real-world performance. In this guide, we’ll walk you through the best options, highlight who each tool is best for, and share insights from our own experience running automations across millions of campaigns.

By the end, you’ll have a clear idea of which marketing automation software fits your goals—and how to put it to work for better leads, conversions, and growth.

What Are Marketing Automation Tools?

Marketing automation tools are software platforms that handle repetitive marketing tasks for you—so you can reach more people with less manual effort. Instead of sending every email, tagging every lead, or updating every customer record by hand, automation tools connect the dots and run those processes automatically.

At their core, marketing automation tools help you:

• Capture leads with forms, popups, or landing pages
• Segment audiences so each group gets the right message
• Send targeted campaigns through email, SMS, push notifications, or ads
• Nurture leads automatically with workflows that move prospects down the funnel
• Track and report results so you can see what’s working and improve future campaigns

Think of them as the engine behind modern marketing campaigns. Instead of juggling a dozen apps or relying on manual follow-ups, automation software keeps your marketing running smoothly in the background—freeing you up to focus on strategy and growth.

How We Chose the Best Marketing Automation Tools

Not every tool that calls itself “marketing automation software” makes the cut. Some platforms only offer basic email scheduling, while others try to do everything but end up overwhelming users. To help you find the right fit, we tested a wide range of tools and scored them against the criteria that matter most for real marketers.

Here’s what we looked at:

• Automation Capabilities
  Can the platform handle multiple channels—like email, SMS, and ads—or is it limited to just one? We also tested how intuitive the workflow builder was, since a clunky interface can kill productivity.
• Integrations & Ecosystem
  Marketing doesn’t happen in a vacuum. The best tools play nicely with CRMs, CMSs, eCommerce platforms, and other apps in your stack. We paid close attention to how easily each platform connected with popular services.
• Ease of Use
  Automation should make life easier, not harder. We noted how steep the learning curve was, and whether the platforms offered templates, onboarding, or solid customer support.
• Reporting & Analytics
  If you can’t measure it, you can’t improve it. We prioritized tools with clear dashboards, actionable insights, and customizable reporting options.
• Price-to-Value
  Marketing automation software ranges from free plans to enterprise contracts that run into the thousands. We compared features to pricing tiers to highlight where you’ll get the most bang for your buck.

This hands-on testing, combined with our team’s experience running automations across millions of campaigns at OptinMonster, gives us a unique perspective. Our goal is simple: to recommend tools you’ll actually enjoy using—and that deliver results.

How We Tested These Tools

We didn’t just skim product pages or copy pricing tables. Our team set up real accounts, built sample automations, and explored each platform the way an actual marketer would. Here’s what that process looked like:

1. Signing Up & Setup
   We created accounts on each platform, tested onboarding flows, and evaluated how easy it was to get started without needing a full technical team.
2. Building Workflows
   We ran test automations—like welcome sequences, cart abandonment flows, and lead nurture campaigns—to see how intuitive the builders were and how flexible the triggers/actions could get.
3. Integrating With Other Tools
   Since most marketers already have CRMs, form builders, and analytics platforms in place, we tested integrations with popular tools (including WordPress, Shopify, and Zapier).
4. Analyzing Reports
   We looked at whether each platform’s analytics provided real insights—things like campaign performance, revenue attribution, and audience segmentation—rather than just vanity metrics.
5. Checking Support & Resources
   Great software is backed by great support. We reviewed each tool’s knowledge base, tutorials, and responsiveness from live chat or email.

By going through this hands-on process, we saw not just what’s promised in the feature list—but how these tools actually perform day-to-day. This helps us recommend options that aren’t just popular, but genuinely useful for marketers looking to grow.

Frequently Asked Questions About Marketing Automation Tools

Many small businesses and startups begin with Mailchimp because of its free plan and simply because of its name recognition. However, the free plan only allows 500 contacts and limits the number of emails you can send to 1000. That doesn’t leave much room for growth in your marketing efforts,

After moving to a paid plan, you may find Mailchimp’s email marketing features lacking and the price increases unsustainable.

Mailchimp’s pricing is based on your total number of contacts, your number of monthly email sends, and the features you need.

Mailchimp can quickly go from affordable to expensive as you grow your email list and start needing tools such as advanced segmentation and send-time optimization.

If you want email marketing software that’s better than Mailchimp and has fairer pricing, there are plenty of options out there.

In this article, I’ll share 6 of the best Mailchimp alternatives and explore the top features, pros/cons, and pricing plans for each one. Then, you’ll be able to find the option that’s best for your business and start building a winning email marketing strategy.

How to Choose the Best Mailchimp Alternative

As you decide which email marketing service is right for you, here are a few considerations:

• Ease of Use: Choose an email marketing service that matches your marketing team’s experience level. Also, consider how much time they’ll have to devote to email marketing. Find the right balance between simplicity and advanced features.
• Automation Functionality: Email marketing automation makes it possible to send welcome email series, abandoned cart emails, win-back campaigns, and more. You’ll need an email platform that makes it easy to set up an automated workflow, which allows these email campaigns to run on their own.
• Segmentation: Email segmentation is absolutely key to sending relevant content to your target audience.
• Testing Capabilities: Your email service should offer easy A/B testing for subject lines. And it’s even better if you can test your sender names and email content. If you plan to do more advanced testing, make sure you choose a platform with multivariate testing capabilities.
• Signup forms and Landing Pages: These should be easy to create and integrate, so you can effectively grow your contact list.
• SMS Marketing: Do you plan to also send SMS marketing messages? Streamline your marketing tools by choosing an email platform with an SMS add-on.
• In-depth Reporting: Go with a platform that lets you adopt a data-driven approach. Don’t even consider any Mailchimp alternatives that don’t offer detailed performance reports that let you access the strengths and weaknesses of your campaign.
• Deliverability Rates: High email deliverability rates are crucial for the success of your email campaigns. Compare the rates of different platforms to ensure your emails reach your subscribers’ inboxes.
• Integrations: Consider how well the platform integrates with any lead-generation tools, CRM (customer relationship management) software, and eCommerce platforms you may use.
• Customer Support: Lack of support is one of Mailchimp’s biggest drawbacks. Other alternative services offer excellent support by email, live chat, or phone.
• Pricing: Of course, none of these great features matter if you can’t afford the platform’s cost. If you’re a small business just getting started with email marketing, look for an option that has a free or low-cost plan but lets you scale up as you grow.

As you read through our list of top Mailchimp competitors, you’ll see information and details on many of these considerations.

Free email services like Brevo are the perfect for business owners looking to start email marketing without committing to a paid plan.

Brevo’s Pricing Structure

Email subject lines are the most important part of any email you send. That’s because they’re the key to whether a reader opens your email, ignores it, or why they go to spam.

This blog will discuss email subject lines, their importance, email subject line best practices, and what to avoid while creating one.

But most importantly, we’ll also share 121 email subject line examples you can use to increase open rates.

Plus, we’ll help you understand the psychology behind them so you can replicate their success again and again.

What Is an Email Subject Line?

An email subject line is a brief preview or a one-line summary of the content of an email that appears in the inbox. The best email subject lines grab readers’ attention, provide value to the recipient, and encourage them to open the email.

Here is an email marketing subject line example.

It is usually the subject line that determines whether a reader would open your email or ignore it.

Why Is a Good Email Subject Line Important?

According to email research by Zippia, 47% of email recipients open an email based on the subject line alone. At the same time, 69% of email recipients report emails as spammy based solely on the subject line.

In other words: your subject lines can make or break your email marketing campaigns.

By using good email subject lines, you can increase open rates, which can help improve click-through rates and conversions.

Email marketing subject lines are important for several other reasons as well, such as:

• Grabbing Attention: Subject lines are the first thing recipients see when they receive an email, and they play a crucial role in grabbing their attention and encouraging them to open the email.
• Setting Expectations: Subject lines also set expectations for the content of the email. A well-crafted subject line should give the recipient an idea of the email and what they can expect to find inside.
• Avoiding Spam Filters: Certain words and phrases can trigger spam filters, causing your email to be marked as spam and potentially end up in the recipient’s spam folder or not being delivered at all. Crafting subject lines that avoid these trigger words and phrases ensures deliverability.
• Higher Open Rates: An engaging subject line can significantly increase the recipient’s likelihood of opening the email. This is especially important in email marketing campaigns, where open rates often measure the campaign’s success.
• Encouraging Engagement: Subject lines can also encourage engagement with the email’s content. A catchy email subject line can entice the recipient to read further, click on links, or take other desired actions.

The subject line is the first impression that the recipient will have of the email. It’s important to make it count.

Let’s see 121+ catchy email subject line examples and the proven principles that make them work.

121 Best Email Subject Lines (and Why They Work)!

FOMO (Fear of Missing Out) Email Subject Lines

One psychological principle that is practically impossible to resist is FOMO, the fear of missing out. You can use this fear in your subject lines by adding an element of scarcity (limited availability) or urgency (limited time).

Email subject lines that include words that imply time sensitivity, like “urgent”, “breaking”, “important” or “alert” are proven to increase email open rates.

Here are some great sample subject lines for emails that use the fear of missing out:

1. Warby Parker: “Uh-oh, your prescription is expiring”
2. JetBlue: “You’re missing out on points.”
3. Digital Marketer: “[URGENT] You’ve got ONE DAY to watch this…”
4. Digital Marketer: “Your 7-figure plan goes bye-bye at midnight…”
5. Digital Marketer: “[WEEKEND ONLY] Get this NOW before it’s gone…”
6. Jersey Mike’s Subs: “Mary, Earn double points today only”
7. Guess: “Tonight only: A denim lover’s dream”

Curiosity Inducing Email Subject Lines

Humans have a natural desire for closure. We don’t like having gaps in our knowledge. You can leverage this desire for closure by leaving your subject line open-ended so subscribers will be curious, like a cliffhanger that can only be satisfied by opening the email.

You can make subscribers curious by asking a question, promising something interesting, or simply saying something that sounds strange or unusual.

Here are some great examples of curiosity-inducing subject lines:

8. Manicube: “*Don’t Open This Email*”
9. GrubHub: “Last Day To See What This Mystery Email Is All About”
10. Refinery29: “10 bizarre money habits making Millennials richer”
11. Digital Marketer: “Check out my new “man cave” [PICS]”
12. Digital Marketer: “Is this the hottest career in marketing?”
13. Thrillist: “What They Eat In Prison”
14. Eat This Not That: “9 Disgusting Facts about Thanksgiving”
15. Chubbies: “Hologram Shorts?!”
16. The Hustle: “A faster donkey”
17. Mary Fernandez: “? a surprise gift for you! {unwrap}”

Funny Email Subject Lines

If your subject line makes your subscribers laugh, they must open it. After all, have you ever read a subject line that tickled your funny bone and didn’t read it?

Being humorous and catchy requires more thought and creativity, but it can pay off in terms of your open rates.

Here are some funny email subject lines to make your subscribers laugh:

18. Eater Boston: “Where to Drink Beer Right Now” (Sent at 6:45am on a Wednesday.)
19. OpenTable: “Licking your phone never tasted so good”
20. Groupon: “Deals That Make Us Proud (Unlike Our Nephew, Steve)”
21. The Muse: “We Like Being Used”
22. Warby Parker: “Pairs nicely with spreadsheets”
23. UncommonGoods: “As You Wish” (A reference to the movie The Princess Bride.)
24. Travelocity: “Need a day at the beach? Just scratch n’ sniff your way to paradise…”
25. TicTail: “Boom shakalak! Let’s get started.”
26. Thrillist: “Try To Avoid These 27 People On New Year’s Eve”
27. Baby Bump: “Yes, I’m Pregnant. You Can Stop Staring At My Belly Now.”
28. Gozengo: “NEW! Vacation on Mars”
29. The Hustle: “Look what you did, you little jerk…” (This one’s a reference to the movie Home Alone. We hope.)

Vanity Appealing Email Subject Lines

Everyone has a bit of vanity. People love to be liked, accepted, and even revered by others. It’s just a part of being human.

That’s why some of the most clever subject lines use vanity to get you to open the email. To do this, you can either promise something that makes the subscriber look better to their peers or invoke the fear of being shamed.

Here are some great examples of clever email subject lines that leverage vanity:

30. Guess: “Don’t wear last year’s styles.”
31. Fabletics: “Your Butt Will Look Great in These Workout Pants”
32. Jeremy Gitomer: “How Have You Progressed Since the Third Grade?”
33. Rapha: “Gift inspiration for the discerning cyclist”
34. La Mer: “Age-defying beauty tricks”
35. Pop Physique: “Get Ready. Keep the Pie Off Your Thighs Returns.”
36. Rapha: “As worn in the World Tour”
37. Sephora: “Products the celebs are wearing”

Greedy Email Subject Lines

You may not think of yourself as a “greedy” person, but it can be tough to pass up a great deal, even if you don’t need the item right now. That’s why sales, discounts, and special offers work well in your subject lines.

However, be careful about offering massive discounts; the higher the percentage, the less reliable its effect on your open rates (perhaps because consumers don’t believe large discounts are real).

Regardless, you can usually expect an increase in click-through rates whenever you offer a discount in your subject line. That’s because the people who open these emails are interested in your offer, so they’re naturally inclined to click.

Here are some great email subject line ideas for hitting your subscriber’s “greed” button:

38. Topshop: “Meet your new jeans”
39. Topshop: “Get a head start on summer”
40. HP: “Flash. Sale. Alert.”
41. HP: “New must-haves for your office”
42. Seafolly: “A new product you won’t pass on”
43. Guess: “25% off your favorites”
44. Rip Curl: “Two for two”
45. La Mer: “A little luxury at a great price”
46. Rapha: “Complimentary gift wrap on all purchases”
47. The Black Tux: “Get priority access.”

Catchy Email Subject Lines

Catchy email subject lines create excitement and encourage readers to open the email.

There are many different ways to grab your readers’ attention. For example, you can create an attention-grabbing catchy email subject line by being controversial, confident, or conversational.

You can also give readers an easier way to achieve their goals by offering a shortcut or a helpful resource (e.g., a lead magnet) that saves time and energy.

Here are a few catchy email subject line examples that capture the readers’ attention in one way or another.

48. Syed from OptinMonster: “ 63-Point Checklist for Creating the Ultimate Optin Form”
49. Syed from OptinMonster: “Grow your email list 10X faster with these 30 content upgrade ideas”
50. Ramit Sethi: “How to email a busy person (including a word-for-word script)”
51. Digital Marketer: “Steal these email templates…”
52. Digital Marketer: “A Native Ad in 60 Minutes or Less”
53. Digital Marketer: “212 blog post ideas“

Customer Pain Points Email Subject Lines

If you understand your buyer persona, you should know their biggest pain points. Use those pain points to get subscribers to open your emails by solving that problem.

Here are some examples of email subject lines that bring out the subscriber’s pain points and offer a solution:

54. Pizza Hut: “Feed your guests without breaking the bank”
55. IKEA: “Where do all these toys go?”
56. IKEA: “Get more kitchen space with these easy fixes”
57. HP: “Stop wasting money on ink”
58. Sephora: “Your beauty issues, solved”
59. Uber: “Since we can’t all win the lottery…”
60. Thrillist: “How to Survive Your Next Overnight Flight”
61. Guess: “Wanted: Cute and affordable fashions”
62. Evernote: “Stop wasting time on mindless work”
63. Duolingo: “Learn a language with only 5 minutes per day”

Retargeting Email Subject Lines

Retargeting emails are sent to subscribers when they fail to complete an action or a step in your sales funnel (e.g., when they abandon their cart or fail to purchase after their free trial). These emails serve to bring your subscribers back to your sales process.

You can write effective retargeting subject lines by overcoming objections, offering something to sweeten the deal, or alerting them that something bad will happen if they don’t take action.

Here are some excellent examples of retargeting email subject lines:

64. Nick Stephenson: “How you can afford Your First 10,000 Readers (closing tonight)”
65. Bonobos: “Hey, forget something? Here’s 20% off.”
66. Target: “The price dropped for something in your cart”
67. Syed from Envira: “Mary, your Envira account is on hold!”

Email Subject Line Best Practices

Following these email subject line best practices, you can craft subject lines that grab your audience’s attention, increase open rates, and drive engagement.

• Segment Your Audience: Tailor your subject lines to different audience segments based on their interests and behaviors. This can increase open rates and engagement.
• Avoid Spam Trigger Words: Avoid using words that are commonly associated with spam, such as “cash,” “earn money,” “free,” or “act now.” These can trigger spam filters and cause your email to be marked as spam, ultimately affecting your email deliverability. This applies to both the subject line and the body of the email.
• Be Clear and Specific: Your subject line should indicate the content and purpose of the email. Avoid vague or overly general subject lines that don’t give the recipient a good idea of what to expect.
• Use Action-Oriented Language: Use strong verbs and action-oriented language to create a sense of urgency and encourage the recipient to take action. This can include words like “limited time offer,” “urgent,” “today only,” or “ending soon.”
• Use Personalization: Include the recipient’s name or other personalized information to make the email more relevant and personalized.
• Keep A/B Testing: A/B test different subject lines to see what works best for your audience. Try different lengths, formats, and styles to see what resonates with your subscribers.

Common Mistakes To Avoid in Email Subject Lines

When you’re creating that perfect email subject line, try to avoid the following mistakes:

• Using Clickbait or Deceptive Language: Avoid using misleading or exaggerated language to entice the recipient to open the email.
• Using All Caps or Excessive Punctuation: Using all caps or excessive punctuation can make the subject line appear spammy and turn off recipients.
• Making False Promises: Only promise something in the subject line delivered in the email’s body.
• Being Too Vague or Generic: Make sure the subject line is specific and provides value to the recipient.

3 Bonus Tips for Crafting Catchy Email Subject Lines

Before choosing a subject line at random, remember these tips for the highest possible open rates.

1. Most People Open Emails on Mobile

Regardless of which of the above techniques you use, make sure your subject line is optimized for mobile users.

While mobile access to email saw a dip at the end of 2018, it’s still the preferred way people access their email.

You can use free marketing tools like EmailToolTester’s subject line checker to see how your sender name, subject line, and preview text will appear on various popular mobile devices.

Simply enter your email details and select which device you want to view:

Then you can see exactly how your email will look in mobile inboxes:

2. Originality is Key

Also, remember that being original is the key to sustainable success with your email subject lines.

The truth is subscribers get bored easily. If you want to engage first-time openers and long-term inactive subscribers, you don’t want them to read your subject line and think, “There’s that weekly newsletter again that I always ignore.”

You should keep things fresh and exciting. And writing good subject lines for emails is the best way to do that.

3. Try Out Emojis

According to a report by Experian, using emojis in your subject lines can increase your open rates by 45%.

We’ve also been testing this at OptinMonster, and we can confirm that the email subject lines with emojis beat the plain text ones!

Here are the top 15 emojis by subject line appearance.

These aren’t necessarily the “best” ones but the most popular. You can get creative with emojis and emoji combinations for your email subject lines.
