Our clients used to disappear after one visit. Now I get replies saying how touched they were to receive the note. Bookings from returning clients are up noticeably.

We were skeptical that a simple thank-you email could make a difference. Three months in, we've had clients return specifically because of the follow-up reminders. Game changer.

Staff adoption was instant — it literally takes 30 seconds. The emails come out sounding warm and personal every time. My clients think I write each one myself.
