We’re about to launch another outreach experiment: mailing letters.
This giving season, we’re planning to send a subset of approximately 4,500 GiveWell donors a physical letter encouraging them to renew or increase their support of GiveWell’s top charities. We’ve never done broad outreach to encourage donations through physical mail before.
In the letter, we plan to share our list of top charities, our overall recommendation for donors, and remit materials for individuals who feel compelled to give. We hope the letter helps communicate our research to a group of individuals who have found our work useful in the past to guide their giving. We plan to assess the success of this experiment based on incremental donations that result from the letters.
