Stay with me… Well, Sam Smith might not be the only one to beg to stay. This is also very true for email marketing. One thing is to get customers due to a successful email marketing campaign, and another is to keep them engaged. With all responsibility, we can say that customer retention is one of the most critical aspects of growing a sustainable and successful business.

While acquiring new customers is job #1, ensuring existing customers stay engaged and loyal can significantly boost the profitability of your business. Retention marketing is one of the simplest yet most effective techniques in this endeavour. By this, we mean crafting efficient retention emails to keep your customers loyal to your company. 

This article explores the nature and hidden knowledge of email marketing customer retention. Let’s review our customer retention email templates tailored for the SaaS, e-commerce, and EdTech industries. We will also provide valuable customization tips to make them work for your brand. Now, it is time to come out into the spotlight and learn how to fight for your precious customers!

What Is a Customer Retention Email? 

A customer retention email is a targeted message sent to existing customers to nurture their loyalty, boost engagement, and encourage repeat purchases or usage. Unlike acquisition emails, which aim to attract new customers, retention emails focus on strengthening the bond between your brand and your existing user base.

These emails often include updates, special offers, educational content, or personalized recommendations that provide value to the recipient and encourage continued interaction with your product or service.

Why Customer Retention Emails Matter 

Why should you focus on retention emails? Here are some key reasons:

1. Cost-effectiveness: Retaining a customer is obviously cheaper than acquiring a new one. Depending on your industry, acquiring a new customer is anywhere from 5 to 25 times more expensive than retaining an existing one. If you’re still unsure that retaining customers is so important, consider research by Frederick Reichheld of Bain & Company that shows increasing customer retention rates by 5 percent increases profits by 25 to 95 percent, according to Harvard Business Review. That’s huge! 
2. Brand loyalty: Apart from the cost-effectiveness benefits, consistent communication helps build trust and long-term loyalty, turning one-time buyers into devoted advocates of your business. You don’t need our recommendations to understand how valuable having a loyal and extensive customer base is.
3. Revenue growth: Repeat customers have already established trust in your business; this is why they tend to spend more than new customers. In this case, retention emails can drive upselling and cross-selling opportunities.
4. Feedback opportunities: Finally, retention emails can help gather valuable information through surveys or customer reviews, enabling you to improve your offerings. A client you know well may bring plenty of insights. 

Retention Email Template for SaaS

This email template for SaaS aims to re-engage mobile app users for buying event tickets. It highlights the app’s new features, customer testimonials with event pictures, and upcoming software improvements and upgrades. The email encourages customers to explore the application and stay connected for future updates.

Why this template works

1. Event personalization: This cool feature focuses on the events selected specifically for the customer. Of course, the choice of events must be based on the consumer’s performance and other important data.  
2. Testimonials: The “Our Users Love Us” testimonials section is a perfect tool to continue building trust and encouraging engagement among existing customers. 
3. Future updates: The layout has a singled-out part that addresses the user to keep them informed about what will be next as the app evolves with features like live streaming or VIP access. 
4. Calls to action (CTAs): The layout has three action buttons encouraging users to learn more about the app.

Customization ideas

• Absence of customer personalization: While the layout features event personalization, it lacks the customer’s name, and this issue must be fixed. 
• Add images: The testimonial part currently lacks images. Adding pictures of real customers, not just their opinions, would be a nice idea to build more trust.
• CTA upgrades: The finishing message, “Stay tuned for these exciting new features!” cries out to be highlighted by your designer. It would be fantastic if this line could also be turned into another CTA button to drive engagement. 

Retention Email Template for E-Commerce

This template is a retention email for a tea and coffee online store featuring the customer’s favorite products. You can find here prices, new arrivals, an exclusive product, and client reviews at the bottom. The main message to the customer is to come back and shop.

Why this template works

1. Visual appeal: Eye-catching visuals, like coffee beans and tea leaves in the shape of a heart and a nice cappuccino cup, showcase recommended products tailored to the customer’s past purchases.
2. Marketing incentives: The template offers the customer’s favorite products and new arrivals, prompting them to purchase.
3. Nice layout: The very “coffee-like” design creates a cozy feeling and nice vibes that uplift the customer’s mood, leading to brand loyalty, which, in turn, should potentially drive sales. 

Customization ideas

• More personalization: Again, just like in the previous retention email template, let’s use personalization fields, mentioning the customer’s name.
• Add images: The “What Customers Are Saying” part currently lacks images. Let’s strengthen brand communication by adding a couple of pictures of satisfied customers! 
• Abandoned cart recovery: You can also add a section reminding the customer of items left in their cart. Pairing it with a discount would be another bright idea. 

Retention Email Template for EdTech

This EdTech retention email is for an online creative courses platform. As you can see, it celebrates the customer’s progress and encourages them to continue learning by exploring new products. The template has upcoming modules, new course additions, an exclusive discount, and testimonials from other learners with their images. The layout has several CTA buttons to resume learning, check out the whole program, learn about new courses, and claim a 20% discount in the “Exclusive Offer” section.

Why this template works

1. Roadmap to more success: The template offers a perfect way to achieve more educational milestones in the “What’s Next in Your Learning Path?” section. It has clear goals with its “Portfolio,” “Skills,” and “Certification” subsections. 
2. Progress tracking: The “Celebrate Your Progress” part showcases progress already made by the user within the educational program. 
3. Encouragement: Motivational messages like “Get 20% Off” in the “Exclusive Offer” section keep users engaged to achieve more.

Customization ideas

• Personalization: The template lacks the customer’s name, which is a clear drawback. Let’s encourage the recipient by mentioning their name to raise involvement and build trust.
• Personal progress updates: Include insights like “You’ve completed X modules this month” to motivate learners.
• Special events: Promote webinars, live Q&A sessions, or group challenges to boost community engagement.
