Most nonprofits track how many legacy society members they add. Almost none track how many they lose — not to death, but to neglect. Donors who quietly update their estate plans and remove you. No notification, no warning, no exit form. And the platforms counting your bequest “intentions”? They’re not measuring retention either. They’re measuring sign-ups. That’s not a pipeline — it’s a wish list. Your legacy society isn’t growing. It’s leaking.
