The usual failure
Win-back never ends. The same 20% off, forever. People who asked to be left alone still get 'we miss you'.
What to make true
A finite sequence. A stop rule. A last honest ask. Then silence. Discount is optional. Respect is not.
Worked example
Keep it this plain. A team uses win-back as if buying the software installed the meaning. It did not. Win-back never ends. The same 20% off, forever. People who asked to be left alone still get 'we miss you'. The move is not a new integration. A finite sequence. A stop rule. A last honest ask. Then silence. Discount is optional. Respect is not.
