Segmented campaigns consistently produce higher opens, clicks, and revenue per recipient, and lower complaints, which protects deliverability.
How to implement email segmentation#
- Define 3 to 5 core segments: new subscribers, engaged, at-risk, customers, and lapsed.
- Capture the data needed at signup and through behavior tracking.
- Build dynamic segments that update automatically as behavior changes.
- Tailor cadence and content per segment; engaged contacts tolerate more frequency.
- Measure revenue per recipient per segment, not just open rate.
How to verify it worked#
Send a test message to seed mailboxes at Gmail, Outlook, and Yahoo, then inspect the Authentication-Results and delivery headers. Repeat after any DNS or sending-platform change.
Common mistakes#
- Over-segmenting into groups too small to learn from.
- Relying on open rates after Apple Mail Privacy Protection inflated them.
Frequently asked questions#
What is the simplest segmentation to start with?
Engagement recency: opened or clicked in the last 30, 90, or 180 days. It drives both relevance and deliverability.
