Email lifecycle
The stages a contact moves through: subscribe, onboard, active, at risk, lapsed and win-back.

In practice
Each stage gets different messages. A welcome series suits new subscribers, a re-engagement message suits lapsed ones, and people who never respond should eventually stop receiving mail.
Verification and sending
Verify at the start, and again before a win-back campaign, because addresses that went quiet may no longer exist.
