If you’re looking to get money from donors in tight economic times, consider giving something away.

Offering new donors a premium can raise response rates by 95 percent and average gift size by 37 percent. At least that’s what M+R Strategic Services found when it worked with four nonprofits on 2008 end-of-year fundraising campaigns.

On average, the net dollars raised per e-mail recipient was 51 percent greater when a premium was offered. In addition, nearly a quarter of donors chose not to take the premium, which kept costs down.
