Almost every tool triggers win-back at 60 or 90 days. That number is arbitrary, and it is wrong for most of your customers in both directions — too early for some, far too late for others. By the time a 90-day rule fires on a customer who used to order every three weeks, they have been buying from someone else for two months.
The agent learns each customer's own gap and triggers at 1.5× that gap. A customer who ordered every 21 days gets contacted at day 32. One who ordered every 120 days is left alone until day 180.
