What is the win-back ladder?

Three gentle nudges to a customer who has stopped coming, on Settings → Promotions and switched on or off as a group under Marketing → Channels ("Win-back & VIP"). Out of the box they wait 14, 30 and 60 days since that customer's last order, and you can change the days and rewrite every message. A customer only ever gets the LATEST rung they qualify for, never the whole sequence — somebody who has been away four months gets one message, not three — and the ladder stops the moment they order again. It runs through your weekly cap, your send window and the same review queue as everything else.
