What Is a Customer Retention Email?
Many businesses have excellent customer acquisition strategies but lack a strategy for keeping existing customers. If you lose old customers as fast as you bring in new ones, your business will never grow.
Customer retention emails are designed to keep existing customers engaged and loyal to your product or brand. They come in different formats, but the goal remains the same: to build lasting relationships and reinforce the value of your products.
Retention emails play a key role in customer satisfaction and loyalty. They help strengthen relationships by keeping customers informed, engaged, and invested in your product.
Why Does Customer Retention Email Matter?
1. Cost-effectiveness
I bet you never knew that acquiring a customer costs way more than retaining the old ones.
According to a survey, over 70% of respondents agree that retaining customers costs less than acquiring new ones. Other research has shown that acquiring a new customer costs up to five times as much money as retaining an existing one.
If you don’t implement an effective retention plan, you’ll waste money trying to replace customers who could have been easily and more affordably retained. One of the most cost-effective ways to keep old customers is through a customer retention email strategy.
2. Staying connected
I signed up for a class last year but never got around to completing it, and I couldn’t get that class off my mind until I finally finished it.
Why? Every time a new cohort started, I received an email from “Ore,” one of the brand reps.
At some point, the class schedule was practically engraved in my brain because Ore wouldn’t stop reminding me how amazing the class was.
Guess what? I eventually signed up. That’s the power of retention emails.
Out of sight is out of mind. When you stop appearing in your customers’ inboxes, they forget you exist.
The trick isn’t to bombard them with emails but to stay visible in a natural and valuable way. Customer retention emails keep your product on their radar by showing them how it improves their lives. If customers interact with you once and never hear from you again, you can’t blame them for moving on.
3. Drives engagement and loyalty
There are many ways to get your message in front of customers: ads, social media, and more. You can even run targeted ads for existing customers. But if you want to speak directly to a specific customer, you need something more precise. This is where email comes in.
Customers leave for different reasons, but with email, you can tailor your retention efforts to address why they might churn.
Also, no one wants to feel like they’re talking to a bot. People connect with brands that make them feel seen. Personalized emails don’t just grab attention; they drive engagement and loyalty.
9 Best Customer Retention Email Strategies that Work
1. Welcome emails
A welcome email is your first shot at making a lasting impression on new and existing customers.
Welcome emails have an average open rate of 80%, making them 75% more likely to be read than other marketing emails.
Your welcome emails are your best bet for introducing your brand, highlighting the value of your product, and starting to build a solid relationship. See some examples of welcome emails here.
2. Promotional emails
The average human loves free things. Give people a discount, free shipping fee, free products, an exclusive offer, or early access, and suddenly, you’ve got their full attention. That’s why promotional emails work so well.
It’s not just about selling or pitching an offer; it’s about rewarding and keeping your existing customers engaged. Whether it’s a limited-time deal, a personalized recommendation, or a sneak peek at something exciting, these emails remind customers why they should stick around.
Here’s an example:
Exclusive Deal Just for You—20% Off Ends Soon!
Hey Abigail,
We love having you as part of our community, so here’s something special for you!
For the next 48 hours, enjoy 20% off your next purchase. This is a little thank-you for being amazing.
Use code THANKYOU20 at checkout.
Hurry! This offer ends soon.
These types of emails make customers feel valued while necessitating urgency.
3. Feature announcement & product update email
When customers feel like they are not making the most of your product, they leave. That’s why feature announcements and product update emails are essential.
These emails remind customers of your product’s value, introduce them to exciting new features, and show them how to benefit from them.
However, these emails should be engaging, easy to digest, and customer-focused.
Tip: Although most firms don’t reveal new features until launch, you can create anticipation in advance. Teaser emails that hint at the launch should be sent out a week or two prior. This builds anticipation.
4. Re-engagement & reminder emails
Life gets hectic, and people forget things. Re-engagement and reminder emails give customers a nudge to take action, be it finishing a free trial, renewing a subscription, or exploring a feature they haven’t explored yet.
Re-engagement emails should feel personal, relevant, and, if possible, irresistible.
An example of a reminder email is a “cart abandonment email.” You’ll be shocked to know that sending an abandoned cart email has caused businesses to earn back 3%- 14% of their sales. The secret is to spark curiosity and be persuasive in those emails.
5. Win-back emails
To build a lasting business, you must stay ahead and know customers who use your products and those who have stopped using them. This is beyond knowing their names and emails; it’s about understanding their experience, pain, and need.
Losing customers is not fun; however, a thoughtful win-back email can turn things around.
When a customer stops engaging with your content, goes quiet, or hasn’t purchased in a while, you should win them back.
Quit sending emails like “We miss you,” “It’s been a while,” and “You should sign up now.” Instead, make your customers see why they should come back. Make it personalized, speak directly to their past interactions, offer compelling value, create a sense of urgency, and make their journey easier by removing barriers.
Be irresistible and make it easy for customers to say “Yes” to you.
6. Survey & feedback emails
Beyond purchasing, your customers can give you a greater advantage regarding feedback.
Instead of racking your head for what’s working and what isn’t, just ask your customers. Survey and feedback emails give your customers a voice while giving you the data you need to improve.
Positive feedback means you have social proof to showcase, while negative feedback is an opportunity to fix what’s broken before more customers leave. Either way, you win.
And, you know what? Consumers like it when brands solicit their feedback. It indicates that you are paying attention and constantly trying to improve your service to them.
The strategy is to ensure your survey takes only a few seconds. Keep it short, simple, and engaging. You can use one-click rating systems (emoji ratings, star ratings, thumbs up/down), offer incentives, and send reminders.
7. Milestone emails
Everyone loves to be celebrated, and your customers are no exception.
Milestone emails acknowledge and commemorate significant events in your customers’ lives, such as their first purchase, brand anniversary, or a personal milestone like a birthday. These emails make customers feel valued, encourage continued engagement, and create a sense of community around your brand.
A timely milestone email can turn casual users into loyal customers.
To stand out, a personalized milestone email with a reward is even better than a simple “Congrats” email.
8. Cancellation emails
Nobody likes losing customers, but cancellation happens. A well-written cancellation email can win back the client or offer insightful criticism to help you grow your company. Instead of viewing them as a loss, see them as an opportunity.
If a customer decides to cancel, you don’t need to make the process frustrating. Be professional, offer alternatives, ask for feedback, and make rejoining effortless. An effective cancellation email can make a “goodbye” into a “see you later.”
9. Thank-you emails
Most businesses exist to make money, but no customer wants to feel like just another sale. A genuine thank you email shows that they are valued beyond their wallets.
A thank-you email is needed
- after a purchase
- when they register for an event
- when they refer a friend
- after they subscribe to your newsletter
- when they renew their subscription
- after they leave feedback
Also, when you surprise customers with an unexpected thank-you email, you’ll turn occasional buyers into lifelong fans.
