DescriptionThis research aims to further our knowledge about why people donate money to charity. I hypothesized that fundraising requests that were a) handwritten, and b) contained positive emotion words related to pro-social motivations would increase donations relative to requests that lacked these qualities. Participants were drawn from the mailing list of a local charitable organization that conducts a yearly direct mail fundraising campaign. Participants were randomly assigned to one of five conditions: 1) Only the standard fundraising packet (standard), 2) standard plus a printed note with positive emotion words, 3) standard plus a handwritten note with positive emotion words, 4) standard plus a printed note without positive emotion words, 5) standard plus a handwritten note without positive emotion words. The results indicated that those who received a handwritten letter donated more money; positive emotion words did not seem to have an effect. These findings can help charitable organizations design and enhance their campaign strategies.
