The Nature Conservancy (TNC) depends on contributions from donors, but had declining response rates from their internal universe—specifically donors who had been inactive for 19+ months.

Abacus® Delivers
We ran a head-to-head test of TNC’s internal model against Abacus Cooperative. With our model, we improved response rates by mailing deeply lapsed donors more effectively and efficiently. We armed TNC with additional data points, such as where else people are spending, to mail into a deeper universe.
The Nature Conservancy was able to identify donors and bring in 8% more from groups lapsed for 37+ months than they had with their internal model.
