This is Leak 05 — the Dormant-Client Leak. Past clients who used you once and drifted, old leads who asked for a quote and went quiet — they're the warmest prospects you'll ever have, and most practices never reach out to them again. Not from neglect, but because a systematic win-back campaign is real work, and it always loses to the demands of current clients. So the database sits there, full of relationships that would return with one good reason and the right timing.
Reactivation AI supplies both — consistently, at scale, without adding to your plate.
