8 Customer Retention Emails That Win Back Lost Customers | 21 Jun, 2025

Turn "They're Gone" into "They're Back" with These Proven Emails. Customer retention email examples show you how to reconnect with customers who've become inactive.

Not every customer sticks around forever. Some buy once and disappear. Some fill their cart and never check out. And some just stop opening your emails.

But here's the good news: You can bring them back.

In fact, studies show that re-engaging lost customers can increase profits by up to 95%, and retained customers are 50% more likely to try new products and spend 31% more than new ones.

That's why customer retention emails matter-and why the smartest brands treat them like gold. In this blog, we're sharing 8 tried-and-tested retention email examples that help ecommerce brands reconnect with past customers. From simple reminders to powerful incentives, these customer retention emails are part of a solid customer win-back strategy. Let's jump in.

What Is a customer retention email?

A customer retention email is a targeted message sent as part of an email marketing campaign aimed at re-engaging customers who haven't interacted with your brand in a while.

These emails are designed to rekindle interest, remind customers of your value, and encourage them to return-whether that means making a purchase, visiting your site, or simply engaging with your content again.

When Should You Send a Customer Retention Email?

Knowing when to send a customer retention email campaign is just as important as knowing what to send.

The truth is, there's no one-size-fits-all timeline-customer inactivity looks different depending on your business type and customer lifecycle.

If you're unsure why customers are leaving, that's a challenge-but it also makes a well-crafted customer retention email even more valuable for regaining their attention

According to HubSpot , 45% of customers who receive a win-back email will go on to open future emails, and a portion of those will become active buyers again.

Why Bother Sending a Customer Retention Email Campaign?

Because it works-and the numbers prove it.

Here's why adding customer retention emails to your ecommerce retention strategy is a smart move:

It boosts revenue: Reactivating just 10% of your inactive email list can lead to up to 30% more revenue.

They're not gone yet: Inactivity doesn't mean a customer is lost forever. Many just need a reminder or a reason to come back.

It improves customer retention: These emails help bring customers back into your ecosystem, increasing lifetime value and strengthening loyalty.

8 Customer Retention Email Examples

1. The "We Miss You" Email
Subject Line:
We Miss You. Come Back for 15% Off.

The classic "We Miss You" email isn't just sentimental-it's strategic. This is your nudge. Your gentle tap on the shoulder. Your, "Hey, remember us?" moment.

Use this as the first step in your win back email campaign. Keep it light, keep it warm, and most importantly offer value.
What to include:

A personal message

A tempting offer (discount, free shipping, etc.)

A reminder of what they loved about your brand

Final Thoughts: It's Not Over 'Til It's Over

Pro tip:
Use Questera's predictive insights to time this email perfectly just when customer interest is about to fade, not after it's long gone.

2. The Abandoned Cart Recovery Email

Subject Line:

Still Thinking It Over? Your Cart's Waiting!

Shoppers abandon carts for dozens of reasons. But most of them are still on the fence. A simple reminder can push them off the fence-straight into checkout. And according to Invesp, increasing customer retention by just 5% can boost profits by 25% to 95%.
Why this works:
These abandoned cart recovery emails remind users what they left behind, sometimes with a soft incentive to return.
What to include: Use automation wisely:
Tools like Questera allow you to automate this based on timing and cart value. Your customer feels remembered, not spammed.

3. The Surprise Gift Email
Subject Line:
A Gift Just for You 🎁 (No Strings Attached)

OK, we said no emojis. But the idea remains: People love surprises. Especially when it feels like a thank-you, not a sales push.

A surprise gift email is the ninja of your customer winback strategy. It doesn't scream, "Buy now!"-but it often leads to a sale anyway.
What to include: Make it personal.
Use the customer's name, show them you remember them, and offer something unique.

4. The "What Went Wrong?" Email
Subject Line:
Tell Us How We Can Do Better

Here's a radical idea: Ask your customer why they left.

It sounds risky but it's pure gold. Why? Because it's not just a win back email example, it's a data mine.
Why it works:
It shows you care. It tells customers you want to grow. And bonus it gives you real insights to improve your retention game.

5. The Product Update Email
Subject Line:
We've Been Busy... And You'll Love What's New

Sometimes people leave because your product didn't meet their needs. Maybe it lacked a feature. Maybe the design wasn't there. Maybe... they just forgot about you.

So remind them.

This re-engagement email campaign is your chance to say: "We heard you. We made it better."
What to include: Segment smartly.
Use email marketing automation to tailor updates based on what they purchased (or almost did). This will improve customer engagement.

6. The Win-Back Countdown Email
Subject Line:
Your Discount Expires in 48 Hours ⏳

Urgency. It's a tried-and-tested psychological trick-and it works brilliantly in ecommerce retention emails

Whether it's a limited-time offer or the last chance to claim a reward, this email nudges the hesitant shopper into action.
What to include: Why it works:
You're giving them a reason to act now, not "maybe later."

Pair this with Questera's behavioral triggers and you've got a powerhouse email.

7. The Social Proof Email
Subject Line:
Still Wondering? Here's What Others Are Saying...

What's more convincing than your sales pitch? A real review from another happy customer.

Use social proof as a retention lever. Show your customer what they're missing out on through testimonials, reviews, or user-generated content.
What to include: Bonus idea:
Show off your product in action-especially if it's been featured in media, by influencers, or trending on social.

8. The Anniversary Email
Subject Line:
Happy Anniversary! Let's Celebrate With a Treat

No, not a wedding anniversary. Their customer anniversary-the day they made their first purchase, signed up, or joined your list.

This is personal. Sentimental. And very effective.
Why it works:
It's an unexpected reminder of a shared history-plus a feel-good excuse to offer a gift or discount.
What to include: Make it feel exclusive.
With Questera, you can automate these based on the user's signup date and purchase patterns.

Final Thoughts: It's Not Over 'Til It's Over

Just because a customer ghosted you doesn't mean they're gone forever. The truth? Most customers are waiting for a reason to return. Your job is to give them that reason-thoughtfully, creatively, and strategically.

Whether it's through a "we miss you" note, a flash deal, or a cleverly timed countdown, your email to win back customers could be the thing that rekindles the spark.

Don't leave it to chance. Use these 8 email types, plug them into a smart system like Questera, and start winning back customers automatically.

Because in ecommerce, it's not just about the first sale. It's about staying in their inbox and on their mind long after.

How Leaderboards in SaaS Drive User Engagement and Boost Customer Retention

# data[].attributes.body
In the competitive world of SaaS, leaderboards have become a strategic tool to encourage user activity and long-term loyalty. By gamifying the user experience, leaderboards introduce healthy competition, motivating users to interact with the platform more frequently. This frequent engagement naturally leads to improved customer retention as users feel more involved and rewarded for their activity.

Leaderboards work especially well when paired with timely customer retention emails. These emails can highlight changes in a user’s ranking, celebrate milestones, or issue friendly challenges—effectively bringing users back to the app with renewed interest. Smartly crafted retention emails remind users of their progress and keep them connected to the platform even when they’re not actively using it.

Segmentation plays a vital role in making leaderboards effective. By grouping users based on experience, location, or activity type, the competition becomes more relevant and attainable. Regularly refreshing leaderboards—weekly or monthly—ensures continuous motivation, while rewards like badges, exclusive features, or discounts enhance the sense of achievement.

Leaderboards also contribute to onboarding and feature adoption. New users can quickly become invested as they see their names on beginner boards, while seasoned users strive for expert-level rankings. When achievements are highlighted through personalized customer retention emails, it fosters a deeper emotional connection to the product.

Overall, leaderboards are more than just a fun feature—they’re a proven tactic to boost engagement, drive adoption, and increase customer retention. When integrated with well-timed retention emails, they create an engaging loop of recognition and motivation that keeps users active, loyal, and invested in the long-term success of your SaaS platform.

In a fast-changing digital world, brands need more than just automation—they need platforms that think, adapt, and grow with their users. This blog compares Questera and Iterable, revealing why Questera is the smarter, AI-powered alternative for companies aiming to scale intelligently.

Iterable offers a dependable, multi-channel solution with tools like email, SMS, push, and in-app messaging. Its drag-and-drop campaign builder, manual A/B testing, and basic segmentation make it suitable for teams managing structured, rules-based workflows. However, it still relies on manual effort and static configurations, which can limit performance and flexibility in a dynamic environment.

Questera, by contrast, is designed with intelligence at its core. Its suite of AI agents—ELMA, SARA, OMNIA, and SEGA—automate the entire customer engagement process. These agents learn from real-time behavior and continuously optimize email flows, user journeys, targeting, and segmentation, delivering tailored experiences without constant manual updates.

With over 75 native integrations—including Salesforce, Google Ads, Mixpanel, Amplitude, and even Iterable—Questera provides a connected, data-rich environment that fuels smarter decisions and seamless operations across platforms.

What truly sets Questera apart is its built-in experimentation engine. Instead of requiring marketers to manually create A/B tests, its AI agents run tests automatically, analyze results in real time, and implement the best-performing tactics—accelerating growth while reducing effort.

While Iterable is effective for traditional campaign management, Questera offers a powerful leap forward. This blog outlines how Questera empowers brands to move beyond automation, embracing intelligent, adaptive marketing that drives measurable growth and long-term success.
