Best of the inbox: building engagement segments from scratch
Sending everything to everyone is why your opens slide. This is the segmentation skeleton worth stealing.

📥 Tiers
— Define 5 buckets by recency — 0-30d, 30-60d, 60-90d, 90-180d, 180d+ since last open/click. Recency predicts deliverability best.
— Mail the hot tiers most, cold tiers rarely — protects your sender reputation by concentrating engagement.

🎯 Apply
— Seed new IPs with the 0-30d tier only — your engaged core does the reputation heavy-lifting.
— Route 180d+ to a re-engagement track — never the main broadcast.

🔁 Maintain
— Re-score weekly, automated — segments are useless if static. Let opens/clicks move people between tiers.

Why these picks: recency-based tiers are the single highest-leverage segmentation, and most lists don't have it.
