Segmentation

Also known as: Segment, Group

Segmentation means splitting your email list into smaller groups so you can send messages that match what each group cares about. It helps you talk to the right people instead of blasting the same email to everyone.

Segmentation is how you sort your email list into smaller groups that share something in common. You might group people by what they bought, where they live, or how often they open your emails. This helps you send messages that feel more personal. It also keeps your list easy to manage.

This matters because people pay more attention when emails match their interests. Segmented campaigns usually get higher opens, more clicks, and better sales results. You send fewer emails that feel random, so unsubscribe rates often drop. Over time, this builds trust and keeps your list healthy.

To get started, pick one simple segment and build from there. For example, separate new subscribers from long term customers and send each group a different welcome or follow up sequence. Watch how each group responds and adjust your content based on real results. Small improvements in relevance can add up to a lot more revenue over time.
