If you’re sending the same email to your entire list, you’re missing out on one of the most powerful tools in email marketing: segmentation.
Email segmentation helps you send the right message to the right people, at the right time. It’s a proven way to boost open rates, increase engagement, and drive more conversions.
Email Segmentation Defined
Email segmentation is the process of dividing your email list into smaller groups (segments) based on shared characteristics. These segments allow you to send more targeted, relevant, and personalised emails.
Instead of blasting one generic message to everyone, segmentation lets you tailor your content to match your subscribers’ interests, behaviours, and needs.

Common Ways to Segment Your List
There are many ways to segment your email list. Here are four of the most effective:
By Demographics
Segment based on subscriber characteristics like:
- Age
- Gender
- Location
- Job title
- Industry
Example: A clothing brand might send different promotions to men and women based on product preferences.
By Behaviour
Segment based on how subscribers interact with your emails or website.
- Email opens and clicks
- Website visits
- Content downloads
- Abandoned carts
Example: Send a follow-up email to users who clicked a product link but didn’t purchase.
By Purchase History
Segment based on what, when, or how often someone buys from you.
- First-time vs. repeat customers
- Product categories purchased
- Average order value
Example: Offer a loyalty discount to customers who’ve made 3+ purchases.
By Engagement Level
Segment based on how active or inactive a subscriber is.
- Highly engaged (opens every email)
- Dormant (hasn’t opened in 90+ days)
Example: Send a re-engagement campaign to inactive subscribers with a special offer.
