Not every customer shops online for the same reasons. Some people purchase regularly, while others only buy once or browse products without placing an order. Sending the same email to everyone may not meet these different needs. As a result, your campaigns can become less relevant and receive fewer responses.
This is why ecommerce customer segmentation matters. It helps online stores divide customers into smaller groups based on shared characteristics, interests, and shopping behavior. Learning how to segment ecommerce customers in mailchimp can help businesses send more relevant messages and build stronger customer relationships.
Mailchimp provides audience management and segmentation tools that help ecommerce businesses organize customer data and create targeted campaigns. In this guide, you will learn how to segment ecommerce customers in mailchimp, from connecting your online store to creating customer groups and sending personalized emails.
Why Is Ecommerce Customer Segmentation Important?

Ecommerce customer segmentation helps online stores understand buyers and create more relevant marketing campaigns. By learning how to segment ecommerce customers in mailchimp, businesses can group customers based on their shopping behavior, purchase history, and interests.

How to Segment Ecommerce Customers in Mailchimp?

To understand how to segment ecommerce customers in mailchimp, start by connecting your online store and organizing customer information. Then, use available purchase data to create meaningful segments and send campaigns that match each group’s needs.
Connect Your Ecommerce Store and Organize Customer Data
The first step in learning how to segment ecommerce customers in mailchimp is connecting your ecommerce platform to Mailchimp. A supported integration can sync customer information and shopping activity between your store and Mailchimp.
Depending on the platform and integration settings, available data may include customer profiles, email addresses, order details, purchased products, and transaction history.
Follow these steps to connect your store:
- Log in to your Mailchimp account.
- Open the integrations section and find your ecommerce platform.
- Follow the setup instructions to connect your store.
- Check your audience data after the synchronization process.
Once the connection is active, organize your contacts in your Mailchimp audience. You can use audience fields and tags to identify different customer characteristics and organize your contact list.
For example, you might use tags to identify first-time buyers, repeat customers, or people interested in a specific product category.
Keeping your information organized makes it easier to create segments and manage your customer database. In many cases, Mailchimp recommends using one primary audience and organizing contacts with tags, groups, and segments instead of maintaining multiple overlapping audiences.
Create Customer Segments Based on Purchase Behavior
After syncing your store data, you can create segments based on customer purchasing activity. This is an important part of how to segment ecommerce customers in mailchimp because purchase behavior helps you group buyers according to their order history, spending habits, and engagement.
Here are some customer segments to consider:
- First-time customers: People who have placed their first order.
- Repeat customers: Buyers who have completed multiple purchases.
- High-value customers: Customers with a high total spending amount.
- Frequent buyers: People who place orders regularly.
- Lapsed customers: Buyers who have not purchased for a while.
- Inactive customers: Contacts with little or no recent activity.
Mailchimp allows you to build segments using available audience and ecommerce conditions. Depending on your integration and subscription plan, these conditions may include purchase date, number of orders, products purchased, and total amount spent.
To create a segment, follow these steps:
- Open the Audience section in Mailchimp.
- Navigate to Segments.
- Select the option to create a new segment.
- Choose the conditions that match your target customer group.
- Review the results and save your segment.
For example, if you want to identify repeat buyers, choose a condition related to the number of orders. If you want to find high-value customers, use a condition based on total spending.
The key is to select criteria that support a clear marketing goal. You do not need to create dozens of segments at once. Start with a few useful groups and expand your segmentation strategy as your business grows.
Use Customer Segments to Send Targeted Email Campaigns
Once your segments are ready, use them to create email campaigns that match each group’s interests and needs. An important step in how to segment ecommerce customers in mailchimp is using each customer group to deliver the right message at the right time.
For example:
- New customers can receive welcome emails introducing your brand and products.
- Recent buyers can receive post-purchase emails with product information or helpful tips.
- Repeat customers can receive exclusive offers or loyalty rewards.
- Lapsed customers can receive re-engagement campaigns that encourage them to return.
You can also include product recommendations based on previous purchases. For example, customers who bought a coffee machine may be interested in compatible filters or cleaning accessories.
Beyond regular campaigns, Mailchimp offers marketing automation features that can help businesses send messages based on specific triggers or conditions. Availability depends on your plan, integration, and account setup.
For example, you might set up a post-purchase email after a customer completes an order. You could also create an automated sequence to reconnect with customers who have not purchased recently.
Make sure each message provides value to its intended audience. Effective email marketing is not only about promoting products. It should also help customers find useful information, discover relevant items, and feel connected to your brand.
Best Practices for Managing Ecommerce Customer Segments

After learning how to segment ecommerce customers in mailchimp, maintain accurate customer data and review campaign performance regularly to improve your segmentation strategy.
Keep Customer Data Accurate and Updated
Accurate customer data helps ensure that each segment reflects buyers’ latest information and activity.
Follow these practices:
- Review customer profiles and contact details.
- Remove duplicate or outdated records.
- Check purchase data synchronization.
- Update customer data when necessary.
- Keep information consistent across Mailchimp and your store.
Also, review tags and segment conditions regularly. For example, first-time buyers should move into the repeat customer segment after making another purchase. Always respect subscribers’ preferences and consent to support responsible email marketing.
Track Segment Performance and Refine Your Strategy
Monitor campaign results to understand how different customer segments respond to your emails.
Key metrics include:
- Click-through rate (CTR): Measures email link clicks.
- Conversion rate: Tracks completed actions.
- Revenue per email: Measures campaign-generated revenue.
- Unsubscribe rate: Tracks subscribers who opt out.
Compare results across segments and adjust your emails, offers, and targeting conditions accordingly. Use campaign analytics and customer insights to identify what works best.
Remember that open rates can be affected by privacy features and automated activity. Evaluate clicks, conversions, and revenue alongside open rates for a more reliable view of campaign performance.
Conclusion
Customer segmentation helps ecommerce businesses understand their buyers and deliver more relevant email experiences. Instead of sending the same message to everyone, you can create targeted campaigns based on purchasing habits, customer value, and engagement.

Start with a few practical groups, such as first-time buyers, repeat customers, and inactive customers. Then, monitor campaign performance and adjust your strategy as your store grows.
