What email segmentation is#
Segmentation divides a list into groups based on behavior, lifecycle stage, demographics, or purchase history so each group receives relevant content.
Why it matters#
Segmented campaigns consistently produce higher opens, clicks, and revenue per recipient, and lower complaints, which protects deliverability.
What SendGrid handles#
Most platforms, including SendGrid, generate the records or settings you need under a domain authentication or sending settings page, and expose bounce and complaint data in reports. Confirm the exact location in SendGrid's current documentation.
What you still own#
- 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.
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.
Does SendGrid set up email segmentation automatically?
SendGrid provides the values and some checks, but publishing DNS, aligning domains, and monitoring results remain your responsibility.
