11 Customer Retention Email Examples & Templates (Plus Writing Tips)

Most businesses spend the bulk of their marketing budget chasing new customers. New revenue feels good, growth charts go up—Everyone’s happy.

But the statistics from Harvard Business Review tell a different story:

• Retaining an existing customer costs 5 to 25 times less than acquiring a new one.
• A 5% bump in retention can increase profits by 25% to 95%.

And email is still the most reliable channel to pull this off.

So yeah, retention emails aren’t just a nice-to-have. They’re probably the highest-return thing you can do with your marketing team right now.

In this guide, I will share the best retention email templates you can use right away—backed with examples and writing tips.

Let’s start!

What Are Customer Retention Emails?

Customer retention emails are messages sent to existing customers or subscribers with the goal of keeping them engaged and happy.

Retention emails can include:

• Welcome sequences
• Win-back campaigns
• Loyalty updates
• Feedback requests
• Subscription renewal reminders
• Birthday messages
• Churn prevention flows

Each type hits a different moment in the customer lifecycle.

Best Retention Email Examples and Templates

Here are some of the best retention email examples, crafted based on different scenarios.

Copy them, tweak it—make it yours.

1. Re-engagement/Retention Email Template for Inactive Customers

The most common type of retention campaign involves reaching out to inactive customers.

The goal is simple:

• Create a list of inactive customers (those who haven’t purchased from you in XX days, or aren’t active on your platform for XX days)
• Reach out them with some kind of offer
• Get them back to be paying customers or as an engaged user.

Subject: 20% off to pick up where you left off

Hi [First Name],

It’s been a while since you last used [Product Name], and I wanted to check in.

We've made some improvements based on user feedback, including [brief mention of one or two relevant improvements].

If you're ready to give it another go, here's 20% off your next [month/quarter/year]:

Code: WELCOME20

The code is valid for the next 14 days.

If there was something that wasn't working for you before, I'd genuinely like to know. A quick reply would be helpful.

[CTA Button: Reactivate My Account]

Thanks,

[Your Name] [Title], 
[Company]

Or, you can use something like this.

Subject: [First Name], a few things have changed

Hi [First Name],

It's been a while since your last [purchased / logged in], and we wanted to share what's new.

Since [date], we've made some updates you might find useful:

- [Improvement or new feature #1]
- [Improvement or new feature #2]
- [Improvement or new feature #3]

If you'd like to give us another look, here's [specific incentive: $15 off your next order / a free month / bonus gift] to make it easy:

[CTA Button: Claim Your [Offer]]

And if something specific made you leave, I'd like to hear about it. Just reply to this email. Your feedback directly shapes what we work on next.

Tips for Re-Engagement Retention Campaigns:

• Start such campaigns when you have something to offer. Like a discount or a new feature that makes your product/platform much better than before.
• Nail the subject line! Check out the re-engagement email subject lines guide to learn more.
• Create urgency without being manipulative. If it’s a limited time offer, perfect. If not, don’t try to be creative. It can hurt your brand image when you try to be manipulative.
• Make the CTA crystal clear.
• A two-to-three email sequence typically outperforms a one-off blast. For example, send a second email right before the sale ends.
• Optimize send times based on customers engagement data. Re-engagement emails often perform better mid-week, mid-morning.

Here’s a retention email example from AWeber:

It’s targeted towards inactive subscribers, to possibly retain them.

The email clearly states what subscribers are going to miss, and it also creates a sense of urgency.

It also helps AWeber to keep their email lists clean. If the subscribers aren’t interacting with them for months or years, they’ve probably lost interest.

At that point AWeber is just wasting their resources by sending emails to inactive subscribers.

2. Loyalty Rewards Email to Retain Customers

If your system provides loyalty rewards (such as affiliate programs giving extra credits or on X purchase you get something free), Great!

Don’t limit yourself to displaying loyalty points on the system/platform dashboard. Reach out to your users via email to inspire them to earn and use more loyalty points.

Here’s how you can do it with this retention email template:

Subject: You're [X] points away from [reward], [First Name]

Hi [First Name],

You've earned [X] points so far. [Y] more will unlock [specific reward: free item, discount tier, exclusive access].

Here are two quick ways to get there:
- [Action #1: e.g., "Shop this week and earn 2x points"]
- [Action #2: e.g., "Refer a friend for 100 bonus points"]

Your rewards:
- Current tier: [Tier Name]
- Points balance: [X]
- Next reward: [Reward description] at [Y] points

Thanks for being a rewards member. We appreciate your loyalty.

[Your Name / Brand Name]

Tips for Loyalty Rewards Retention Emails:

• Send it Monthly as a summary, or triggered when a customer reaches 75%+ of their next reward tier.
• You can also send loyalty program retention emails after user activity drops off, before points expire, and during promotional periods.

3. Subscription Renewal Retention Email

Most companies send renewal reminders 60 days before the charge date.

With the email they provide exact date, pricing, and links to manage renewal details.

This builds trust with the customers.

Even if customers choose not to renew their subscription, they will gladly remember you when they need a similar service in the future.

In some countries, these reminders are legally required, especially with auto-renewal subscriptions.

So, how can you fulfill legal and retention requirements at the same time?

• Show customers how your product helped them with proper statistics, and personalization.
• Provide clear CTA and guidelines.
• Don’t force customers with renewal (like adding a fee to cancel subscription or going out of topic and comparing your product with the competitors).

Subject: Your [Product Name] subscription renews on [Date]

Hi [First Name],

Quick heads-up: your [Product Name] [plan name] subscription renews on [Date].

Here's what you got out of [Product Name] this year:
- [Usage stat #1: e.g., "247 documents processed"] 
- [Usage stat #2: e.g., "1,340 errors caught"] 
- [Usage stat #3: e.g., "Saved an estimated 18 hours"]

Renewal details:
- Plan: [Plan Name] 
- Amount: [Price] 
- Payment method: Card ending in [XXXX]

You don't need to do anything to continue. If you would like to change your plan or update your payment details, you can do so here: [link]

We are glad to have you,

[Your Name / Brand Name]

4. Feedback Request Email to Improve Retention

Customer feedback request emails play a much bigger role in retention than we expect.

By sending a feedback request email you are assuring customers that you are ready to hear their voice, and act upon it. The product is improving.

The product is improving. The bug that causing customers to find alternatives might get fixed in the next update.

So, customers choose to stay with the current product.

Subject: What's one thing we could do better?

Hi [First Name],

You've been with [Brand Name] for [X months/years]. We'd like to hear how it's going.

We're working on making things better, and your input helps us decide what to prioritize.

If you have 3 minutes, we'd appreciate your honest feedback.

[CTA Button: Share Your Feedback]

Every response is read by a real person. Good, bad, or mixed, it all helps.

As a thank you, everyone who completes the survey receives [incentive].

Thanks,

[Your Name]

P.S. Not in the mood for a survey? Just reply with one thing we could improve. That works too!

Tips for Feedback Request Emails:

• Make the survey as quick as possible.
• Actually work on improving your product based on user feedback.
• You can also collect customer feedback when they decide to leave. Ask them what went wrong or what could have been done.
• Properly categorize your email lists for surveys. For example, send them to new customers after a month or two has passed, or when you need customer feedback to decide on new features.

5. Milestone and Anniversary Email

Celebrating achievements fosters a positive emotional association with the brand.

A data recap reminds people of the value they’ve already received, making them less likely to leave.

Here’s an email template for celebrating milestones and anniversaries to improve the retention rate:

Subject: [X] years with us, [First Name]

Hi [First Name],

It's been [X years/months] since you joined [Brand Name], and we wanted to mark the moment.

- [Personalized stat #2: e.g., "14 different products tried"]
- [Personalized stat #3: e.g., "Member since [date]"]

As a thank you, here's [discount/gift detail: e.g., "15% off your next order with code ANNIVERSARY15"].

[CTA Button: Claim Your [Discount/Gift]]

Thanks for being part of this. Here's to more!

[Your Name / Brand Name]

6. Exclusive Offer Email for Retaining VIP Segments

The word “exclusive” only works when the offer truly isn’t available to every subscriber.

If everyone receives the same email (or same discount every time for example), trust erodes quickly.

VIP for example can be:

• High-value customers (customers on your highest-tier plan)
• Customers with longest tenure
• Top affiliates
• Engaged community members
• Professional or enterprise accounts

Use this email template for product launches, seasonal events, or when VIP engagement starts dipping. This will definitely help you retain more VIP customers.

Subject: [First Name], this one's just for you

Hi [First Name],

As one of our most valued customers/members, we wanted to share this with you before anyone else sees it.

Your exclusive offer:

[Specific offer: "$25 gift card," "48-hour early access," or "Free upgrade for one month"]

This offer is only available to [describe the qualifying group, e.g., "customers on our Pro plan" or "members with 2+ years"], and it expires [date].

Thanks for being with us,

[Your Name / Brand Name]

[Your Name / Brand Name]
