Email Segmentation (2027): 15 Segments That Work and How to Set Them Up
Email segmentation means splitting your list into smaller groups based on shared traits or behavior, so each group gets emails that fit them. Instead of sending the same message to everyone, you might send product news to recent buyers, a re-engagement email to inactive subscribers and beginner tips to new sign-ups. Relevant emails get more clicks and fewer unsubscribes. Every major email tool supports segments, including free plans from MailerLite, Klaviyo and Kit.
- Segment by behavior, purchase history, engagement, interests or profile data.
- Start with 3 to 5 segments you'll actually use.
- Tags and custom fields store the data; segments are saved filters that update automatically.
- Engagement-based segments protect deliverability.
- Ecommerce tools (Klaviyo, Omnisend) segment by orders and products automatically.
Why segment your email list
- More relevant emails lead to more clicks and sales.
- Fewer unsubscribes and spam complaints.
- Better deliverability because you send less to unengaged people.
- Clearer reporting: you see which groups respond to what.
Types of segmentation
| Type | Based on | Example |
|---|---|---|
| Behavioral | What people do | Clicked a pricing link, visited a product page |
| Purchase | What and when they buy | First-time buyers, repeat customers |
| Engagement | How active they are | Clicked in the last 30 days, inactive for 180 days |
| Interest | What they told you or clicked | Topics chosen at sign-up |
| Demographic | Profile data | Country, job role, company size |
| Lifecycle | Where they are in the relationship | Lead, trial, customer, former customer |
| Source | Where they signed up | Webinar, checkout, blog form |
15 segments that work
- New subscribers (joined in the last 30 days).
- Engaged subscribers (clicked in the last 90 days).
- Inactive subscribers (no clicks in 180 days).
- First-time buyers.
- Repeat customers (2 or more orders).
- High-value customers (top spenders).
- Lapsed customers (no order in 6 months).
- Abandoned cart or browse visitors.
- Product or category interest (clicked or bought from a category).
- Webinar registrants who didn't attend.
- Trial users who haven't completed setup.
- Leads who visited the pricing page.
- Subscribers by country or time zone.
- Subscribers by chosen topic.
- Customers who left a low rating, for follow-up.
How to collect segmentation data
- Ask one or two questions at sign-up, such as "What are you most interested in?"
- Tag subscribers by the form or lead magnet they used.
- Track clicks on topic links and tag automatically.
- Connect your store or CRM so purchases sync.
- Use preference centers where subscribers choose topics and frequency.
Ask only for data you'll use, and explain why.
How to set up segments
- Decide the first three segments you'll send to differently.
- Create the tags or fields your tool needs.
- Build each segment with filters, such as "clicked any campaign in last 90 days".
- Use segments in campaigns and as automation triggers.
- Compare results by segment after a month.
Examples of segmented campaigns
| Segment | |
|---|---|
| New subscribers | Welcome series and best content |
| Repeat customers | Early access to new products |
| Lapsed customers | "Here's what's new" plus a reason to return |
| Inactive subscribers | Re-engagement email, then removal |
| Pricing page visitors | Case example and invitation to a call |

Segmentation and privacy
Use data that subscribers gave you or that comes from their activity with your business, keep it secure and respect consent rules. Don't buy third-party data to enrich your list without a clear legal basis.
Common mistakes
- Creating dozens of segments you never use.
- Segments so small that results mean nothing.
- Asking for too much data at sign-up.
- Forgetting to exclude buyers from sales campaigns.
- Never cleaning inactive subscribers.
Terms explained
- Segment: a group of subscribers matching filters, usually updated automatically.
- Tag: a label added to a subscriber, often by a form or click.
- Custom field: a stored piece of data, like country or plan.
- Preference center: a page where subscribers choose topics and frequency.
- Suppression list: contacts who shouldn't receive certain emails.
A starter segmentation plan
Week 1: create an "engaged" segment (clicked in the last 90 days) and an "inactive" segment (no clicks in 180 days). Send your next campaign only to engaged subscribers and a re-engagement email to the inactive group.
Week 2: tag subscribers by sign-up source, such as blog form, checkout or webinar, so you know where each person came from.
Week 3: add one interest question to your sign-up form and a link-click tag in your newsletter for each main topic.
Week 4: for stores, connect your shop and build "first-time buyers" and "repeat customers" segments; for service businesses, build "leads" and "clients" segments from your CRM.
After a month, compare click rates and unsubscribes by segment. Most businesses see which groups respond best and can stop sending irrelevant emails to the rest.
Segmentation in automations
Segments become more powerful when they trigger automations. A subscriber entering the "lapsed customer" segment can start a win-back series; one entering "visited pricing twice" can notify sales. Keep the rules simple, document them, and check that a person can't be in two conflicting automations at once.
Segmentation for B2B lists
Business-to-business lists can segment by industry, company size, job role and stage in the sales process. A CRM integration lets you exclude current customers from prospect campaigns and send customers product updates instead. Keep the number of segments small enough that you can write relevant content for each one; three well-served segments beat ten that all receive the same email.
Our verdict
Segmentation is the simplest way to make emails more relevant. Start with a few useful groups (new subscribers, engaged readers, customers and inactive subscribers) and send each one something that fits. MailerLite and Kit handle this well for most small businesses; Klaviyo and Omnisend are best for stores.

FAQ
What is email segmentation?
Dividing your list into groups so each receives more relevant emails.
How many segments should I have?
Start with three to five you'll actually use.
What is the difference between tags and segments?
Tags label individual subscribers; segments are filters that group subscribers by tags, fields or behavior.
Can I segment on a free plan?
Yes. MailerLite, Klaviyo and Kit all support segmentation on free plans.
What is the best segment to start with?
Engaged versus inactive subscribers; it improves results and deliverability.
Does segmentation improve deliverability?
Yes. Sending to engaged subscribers reduces complaints and bounces.
How often do segments update?
Most tools update dynamic segments automatically as subscriber data and activity change.
Can I segment by location?
Yes, using sign-up data, IP-based location or store addresses, depending on the tool.
Do I need a big list to segment?
No. Even a few hundred subscribers benefit from separating customers from prospects and engaged readers from inactive ones.
What is behavioral segmentation?
Grouping subscribers by what they do, such as clicks, purchases, page visits or time since their last order.
Can segmentation hurt results?
Only if segments are so small or numerous that you can't write good content for each, or if you exclude people by mistake. Check segment sizes and filters before each send, and start with a few broad, useful groups.
