Email retargeting strategy: Recover lost sales and improve conversions

Email retargeting occurs when a brand reaches out to people who visited their store but didn’t make a purchase. 

Sounds familiar? Picture this — you added something to your cart, got distracted, and then, boom, much later, an email pops up reminding you about it. That’s email retargeting in action.

If you run an online store, you’ve seen it happen. People visit the website, add items to their cart, and then disappear. It can hurt to lose sales from shoppers, especially when they were clearly interested.

Here’s the good news: 

Email retargeting helps you reconnect with those visitors. It sends personalized emails based on what people actually did on your website. 

In this guide, we’ll explain how email retargeting works and share real-world examples. You’ll see best practices to use in 2026 to recover lost sales and engage your audience like never before.

Let’s get started!

Email retargeting: Key takeaways

• What it is: Email retargeting means sending targeted emails to people who visited your store but didn’t complete a purchase. It’s all about reconnecting with interested shoppers.
• Why it matters: Many visitors leave a website without completing the order process. An email retargeting strategy will help recover lost revenue by reminding them about the products they showed interest in.
• How it works: The system tracks behavior, such as viewed products or abandoned carts, and then sends automated emails based on those actions. The combination of behavior data with timely automation helps reach a person at the right moment.
• Top use cases of email retargeting are:
  • Abandoned cart emails
  • Browse abandonment reminders
  • Win-back campaigns for inactive customers
• Best practice: Segment your audience and tailor emails to them. Timing also matters, so send emails when prospects are most likely to return.
• Expected impact: When done right, email retargeting improves conversions, increases customer engagement, and delivers a stronger ROI for your ecommerce store.

What is email retargeting?

Email retargeting is the practice of sending personalized emails to people who have interacted with your brand but did not buy anything. This helps brands reconnect with shoppers who have shown interest in their products.

Unlike retargeting ads that follow users across websites and social media, email retargeting happens directly in the inbox. It uses behavior data like product views or abandoned carts to trigger timely messages.

This matters because these emails bring back interested shoppers using reminders, product suggestions, or helpful nudges.

You can also use email marketing retargeting for upselling and cross-selling products to existing customers. The image below is one of the retargeting email examples showing how a brand encourages a shopper who has abandoned their cart: 

How does email retargeting work?

Email retargeting works by combining behavior data triggers with automation. When someone interacts with your store, their actions and inactions can trigger a personalized email that encourages them to return.

Several types of actions can be tracked, such as:

• Product pages a visitor viewed
• Items added to a cart or removed from it
• Completed purchases
• Email activity like opens or clicks

This information is usually collected through cookies, ecommerce tracking events, and first-party data from your online store or email platform. When a tracked action happens, an automated email is sent.

For example, if a shopper adds an item to their cart but leaves without buying, you can send a reminder email encouraging them to complete their purchase. Many ecommerce brands use abandoned cart emails for this purpose.

Another tracking tool involved in some campaigns is an email retargeting pixel. This is a tiny image embedded in the email’s HTML that helps measure opens and engagement.

Keep in mind that tracking may not always be perfect. Some browser privacy settings and email protections can limit the data available.

Email retargeting best practices

Getting results from email retargeting depends on timing, relevance, and clarity. You don’t need more emails. You need better ones. That’s what separates average remarketing email campaigns from high-performing ones.

Here are email retargeting best practices that actually work:

• Send fast for high-intent flows: Act quickly when interest is high. Send your first abandoned cart email within one hour. Then, follow up again within 24 to 48 hours.
• Use behavioral segmentation: Group prospects based on their actions. This can include viewed categories, added-to-cart shoppers, repeat visitors, or inactive subscribers. This is key to a strong email retargeting strategy.
• Personalize the message: Show the exact items a shopper viewed or left behind. Also, use clear product images to make the email feel relevant and timely.
• Use clear CTA buttons: Tell shoppers exactly what to do next. Use buttons like “Return to your cart,” “Complete purchase,” or “View item.” Additionally, always avoid vague wording.
• Control timing and frequency: Too many emails can push people away. Use triggers and spacing to avoid fatigue and unsubscribes.
• Add value beyond discounts: Discounts help, but they are not everything. Add reviews, trust badges, shipping details, and product benefits to build confidence.
• A/B test continuously: Test subject lines, send times, layouts, offers, and CTA text. Small changes can improve your email marketing retargeting results over time.
• Design for mobile first: Most emails are opened on mobile. Keep layouts simple, use large buttons, and make content easy to scan.

Real retargeting email examples

Email retargeting campaigns can take many forms depending on user behavior and purchase stage.

Here are common retargeting email examples used by ecommerce brands as part of an effective email remarketing strategy:

• Abandoned cart email
• Browse abandonment email
• Back in stock email
• Upsell email
• Cross-sell email
• Replenishment email
• Win-back email

Abandoned cart email

Brand: Alo Yoga

The abandoned cart email is sent shortly after the session ends, while the intent to buy is still high. This helps reinforce product value and encourages the shopper to return. 

The email above includes the exact products left in the cart, with images, pricing, and a direct link to checkout. It highlights urgency with a low-stock message and uses a bold CTA to push people back to checkout.

Browse abandonment email

Brand: Rebecca Udall

These emails are triggered when someone views a product but leaves the site without adding anything to their cart. They serve as a reminder while the product is still fresh in your mind.

Your browse abandonment email should include the product viewed, paired with soft, persuasive messaging. This will encourage the shopper to take another look without feeling pressured.

Back-in-stock email

Brand: Lululemon

A back-in-stock email is triggered when a product a shopper showed interest in or tried to purchase becomes available again. It is often sent to users who signed up for restock alerts or viewed the product before it sold out.

The email above includes the restocked product, clear availability messaging, and a direct CTA to shop before it sells out again.

Upsell email

Brand: Calendly

It’s triggered after a shopper shows interest in a product or completes a purchase. It targets users who may consider upgrading to a higher-value option. This is a type of post-purchase email that increases customer lifetime value.

The email presents premium alternatives or upgraded versions with additional features. It focuses on showing more value to encourage a higher purchase.

Cross-sell email

Brand: Conair

A cross-sell email is triggered after a purchase or based on browsing behavior. It focuses on recommending products that complement what the shopper viewed or bought.

This email includes related items that naturally pair with the original product. It helps increase order value by suggesting useful additions.

Replenishment email

Brand: Graza

Such emails are triggered based on purchase timing. They target customers who are likely running low on a product they previously bought.

Replenishment email reminds shoppers to reorder, often featuring the same product with a quick link to purchase again. It keeps the process simple and convenient.

Win-back email

Brand: Duolingo

A win-back email is triggered when a customer has not engaged with the brand for a while. It targets inactive subscribers who haven’t opened emails or made recent purchases.

This win-back email reintroduces the brand by highlighting products, collections, or updates. It encourages the shopper to return and engage again.

How to create a retargeting email

Manually following up with every shopper who leaves your site isn’t feasible, and that’s exactly where automation changes everything. 

Instead of reacting late, automation allows you to respond instantly to customer behavior, sending the right message at the right time without manual effort. 

This is what makes retargeting emails so effective: they work in the background while you focus on growing your business.

That’s where Omnisend comes in. It combines automation, segmentation, and personalization into one platform, making it easy to create behavior-based campaigns that actually convert. 

From pre-built workflows to dynamic product recommendations, Omnisend gives you the right tools to turn missed opportunities into revenue.

Here’s how you can build a retargeting email that actually drives results.

Choose the goal and trigger

The type of retargeting email you create depends on the action you want to recover. Are you bringing back cart abandoners, reminding casual browsers, or re-engaging inactive subscribers?

Most remarketing email flow examples fall into three categories:

• Cart abandonment
• Browse abandonment
• Win-back campaigns

Each one targets a different stage of the customer journey and requires a slightly different message.

Platforms like Omnisend provide automated workflows for cart abandonment and other categories to help you recover lost sales. With Omnisend, you can choose from pre-built workflows structured around customer behavior for each of these triggers.

So, you spend less time setting things up and more time refining what actually matters, your messaging and targeting.

Define audience and exclusions

Once your goal is clear, the next step is identifying exactly who should receive your email. To make email retargeting more effective, start by defining your audience. 

Learn how to build an email list from scratch to make your campaigns reach the right people. Also, segment your audience based on behavior, so each message feels intentional and not generic.

For example, you should target:

• Users who added products to their cart but didn’t complete checkout
• Visitors who viewed specific products without taking action
• Subscribers who haven’t engaged with your emails in a while

It’s just as important to define exclusions to avoid over-sending or creating friction. Exclude:

• Recent buyers
• Highly engaged subscribers
• Users who have already clicked but are still within a conversion window

This balance keeps your campaigns precise, which directly improves engagement and conversion rates.

Build the email

This is where intent turns into action. Your email should be clear, focused, and easy to act on. Start by anchoring the message around the user’s behavior, then guide them back with a seamless experience.

Your email should include:

• The exact product viewed or abandoned
• High-quality product images
• Short, benefit-driven copy that reinforces value
• One clear and compelling call to action

Avoid adding too many competing elements, because clarity drives clicks. 

Use Omnisend’s personalization features to insert dynamic product details and recommendations. Omnisend also offers ready-made retargeting email templates to help you quickly design emails.

Set timing and cadence

Even a strong email will underperform if the timing is off, which is why this step matters. You want to reach users while their intent is still fresh, without overwhelming them with too many messages.

A simple structure works well for most campaigns:

• First email: Sent within one hour of the action
• Second email: Sent 24-48 hours later as a reminder

For win-back campaigns, spacing matters, so emails are typically spread across several days or weeks, depending on inactivity. This ensures your emails feel like helpful reminders rather than aggressive follow-ups.

Test and measure

Retargeting improves over time, not overnight, which is why testing should be built into your process.

Focus on experimenting with the elements that directly influence performance. This means:

• Using catchy email subject lines to improve open rates
• Adding wording that drives clicks for calls to action
• Adjusting send times based on engagement
• Using better layouts to improve readability

Also, track key metrics such as open rates, click-through rates, and conversions to understand what’s working.

These insights will help you refine your campaigns continuously and turn small improvements into meaningful revenue.

Summary

Email retargeting helps you recover lost revenue by reconnecting with shoppers who already showed interest but didn’t convert. When used well, they turn missed opportunities into steady, repeat sales without increasing your marketing spend.

To get the best results, focus on using clear triggers based on real user behavior and segmentation. Also, send emails at the right time while intent is still high. 

These fundamentals keep your campaigns effective and prevent your emails from feeling generic or intrusive.

Platforms such as Omnisend can simplify the process with ready-made automation tools that’ll help you launch faster and scale. 

Start applying these strategies, and you’ll build a system that consistently brings customers back and supports long-term growth.
