What's Email Segmentation and Why Does It Matter?
To break through today’s crowded inboxes, brands need more than generic, basic emails. Delivering content that aligns with your audience’s unique interests and habits is key—and that’s exactly what email segmentation helps you achieve.
Segmentation empowers marketers to deliver the right message to the right person at the right time — resulting in better engagement, higher conversions, and a significant boost to ROI. In fact, our own testing at Stimulate Agency has shown that segmented email campaigns can generate over 890% more revenue per recipient compared to non-segmented campaigns.
Talk about a lift in results!
Email segmentation is all about breaking your email list into smaller groups based on information like demographics, purchase history, browsing habits, engagement, location, preferences, and more. This strategy helps you send messages that feel more personal and relevant to each group.
Why Segmentation is a Game-Changer for Email Marketers
- More Engagement: Sending emails to the right group results in more click-through rates and meaningful interactions.
- More Sales: People trust emails that feel personal, which makes them more likely to buy.
- Fewer Spam Issues: Targeted emails are less likely to end up in spam, so more people see them.
The benefits couldn't be more obvious: if you're not leveraging segmentation right now, you're leaving significant results on the table.
Key Data Points You Need to Collect for Effective Segmentation
To build effective segments, you need to collect data about your audience. Understanding your customers' needs and interests starts with the right data. Using these details lets you create content that feels personal, unique, and relevant.
Here are the key data points Stimulate prioritizes for strong segmentation:
Behavioral Data:
Track website visits, abandoned carts, and email engagement to uncover implicit interests and buying signals.
Example: Create a campaign promoting top anti-aging products to subscribers who often view your anti-aging collection, highlighting best-sellers and customer favorites.
Demographic Data:
Collect age, gender, or location to target customers with region-specific campaigns or tailored product recommendations.
Example: Promote winter gear to customers in colder climates.
Transactional Data:
Identify your subscriber's habits, such as purchase frequency, customer lifetime value (CLV), time between purchases, and other transaction data to tailor your campaigns better.
Example: Send an exclusive loyalty program invitation to high spenders, highlighting VIP perks like bonus points, early access to new launches, or special rewards tailored to their purchasing habits.
Zero-Party Data:
Use quizzes, surveys, and popups to understand what your customers want, need, and care about.
Example: Use survey responses about skin concerns to recommend targeted skincare products.
Psychographic Data:
Find out what your subscribers care about to create tailored and impactful messaging (like hobbies or lifestyle).
Example: Market eco-friendly products to customers who value sustainability.
How to Collect Data for Effective Marketing Segmentation
Now that you know what data to collect, the next step is figuring out how to gather it effectively — and at scale. Your segmentation strategy is only as strong as the quality and quantity of the data you collect. Here are practical, proven methods to help you gather all the data you need for effective segmentation:
Use Popups to Collect Zero-Party Data
Use popups to ask quick questions and gather preferences directly from customers in exchange for a discount or incentive.
Example: “What’s your main skincare concern?” (e.g., dryness, anti-aging)
Gather First-Party Data Through Website Tracking
Monitor customer behavior on your website to identify interests and buying signals.
Example: Target users who view your anti-aging collection with a campaign featuring anti-aging best-sellers.
Post-Purchase Surveys
Ask short questions after purchase to learn more about customer motivations.
Example: What made you choose our brand over others? (e.g., quality, affordability, unique offerings, trusted reputation)
Interactive Quizzes
Engage users with quizzes that provide personalized results while collecting valuable insights.
Example: A “Find Your Skin Type” quiz that asks about skin concerns (e.g., dryness, oiliness, sensitivity) and recommends tailored products.
Loyalty Programs
Track loyalty program activity to uncover additional transactional, demographic, and behavioral data about your customers.
Example: Offer loyalty points for sharing birthday details so you can tailor campaigns based on the subscriber's age.
Follow-Up Feedback
Send a follow-up after abandoned carts or service inquiries to gather feedback on roadblocks.
Example: “What stopped you from completing your purchase?”
These methods will let you collect valuable data to power advanced segmentation, delivering personalized and impactful campaigns.
Top Email Segmenting Strategies
Data collection is step one, but how you use that data can make or break your results. Here's how to turn your insights into segments that drive personal campaigns, better engagement, and amazing results:
Engagement Segments
Group subscribers based on how they interact with your emails, such as openers, clickers, website browsers, or unengaged users.
Example: Send a re-engagement campaign with an interactive quiz to subscribers who haven’t visited your site in 90 days, encouraging them to explore personalized product recommendations and reignite their interest in your brand.
First-Party Data Segments
Target customers based on their browsing behavior, add-to-cart activity, or past purchases.
Example: Promote “Trending 2025 Hoodie Styles” to customers who previously viewed or purchased hoodies, highlighting best-sellers from a category they’ve previously shown interest in.
Zero-Party Data Segments
Leverage customer-provided data from quizzes, surveys, or popups to create highly personalized segments.
Example: Promote anti-aging products to people who indicated they were interested in anti-aging or are 40+ years old.
Lifecycle Segments
Categorize customers based on their customer journey stage, such as prospects, new customers, loyal customers, or lapsed customers.
Example: Offer lapsed customers an extra incentive to repurchase, such as a 20% discount or free shipping, or nurture new customers with a free mystery gift on their second purchase to encourage repeat shopping.
Demographic Data
Segment by factors like age, gender, location, or income to personalize messaging even more.
Example: Promote winter coats to customers in colder regions during seasonal transitions.
These strategies help you get the most from your data by creating campaigns that cater to your customer’s specific needs and preferences. When used effectively, segmentation can turn email marketing into a tool for both quick wins and lasting loyalty.
