Overview
Most email programs treat a subscriber who has opened every email in the last 90 days the same as one who hasn't opened in 120 days. They receive the same content at the same frequency. The engaged subscriber is undersupported; the disengaging subscriber is being slowly pushed toward marking the email as spam.
The Engagement Tier Email Segmentation builds a tiered system where frequency and content intensity are calibrated to engagement level — increasing value delivery for highly engaged subscribers while reducing send pressure on disengaging ones before it becomes a deliverability problem.
What you get: - 5 engagement tiers with behavioral definitions - Frequency and content rules per tier - Engagement score calculation (open + click weighted) - Tier movement logic: how subscribers graduate up or down - Deliverability protection model: why this segmentation protects sender reputation - Revenue impact model: why concentrating effort on Tier 1–2 improves total revenue
Built for: CRM teams and email marketers managing list health, deliverability, and revenue concentration simultaneously.
