Wonder Why Your Appeals Underperform?

Reaching the right supporters has never been harder. Support for charities spreads through conversations. Missing those conversation leads to:

Wasted print and postage

Lower response rates

Campaign budgets stretched too thin

KSS Uuncovering a New Audience in the Unlikeliest of Places

Air Ambulance Charity Kent Surrey Sussex (KSS) needed to keep donations high, despite the fact that many in the region had already heard their message and the ad budget couldn’t increase. To find new supporters, they partnered with Herdify to try a different approach.

“Given it was our first use of Herdify, and a test, I think we can count that as a real success. The increasing response rates by Herdify score clearly shows the model can help predict responders. And uncovering an unknown audience for us is massive.”

Predicts supporters likely to consider leaving a bequest and helps manage long-term legacy pipelines.

Face to face

Herdify directs teams to the areas where word-of-mouth is already working for you.

Events

Plan field activity in advocacy clusters, turning casual “I’ve heard of you” into “Where do I sign up?”
