Engagement tier

Core, active, casual, dormant — behaviour, bucketed honestly.

An engagement tier compresses a person's behaviour into an operational label. A useful scheme is: core (reads consistently and has paid), active (reads consistently), casual (reads sometimes), dormant (stopped reading).

Tiers matter because averages lie: a 40% open rate can be half your list at 80% and half at zero — two completely different businesses with identical dashboards.

In ListFunnel

Tiers are computed from opens and purchases per person, recomputed continuously, and drive the built-in auto-segments.
