Segmentation is a relevance engine

Broad campaigns dilute intent. Segmentation lets teams match message timing, value proposition, and CTA strength to actual customer context.

Practical segmentation stack

• Lifecycle stage: new, active, slipping, churn risk.
• Behavior: feature usage, click depth, recency.
• Commercial value: plan tier, account size, expansion potential.

What to optimize first

Start with subject-line relevance and offer fit per segment. Then refine content blocks and send windows based on response behavior.
