Online fundraising among 32 nonprofits is up 26 percent over 2008. That’s the good news. The not-so-good news is the average donation decreased by 21 percent. So says the 2009 eNonprofit Benchmarks Study, co-authored by M+R Strategic Services, a nonprofit advocacy group, and the Nonprofit Technology Network. Other findings: Email response rates held steady this year, compared with previous declines. The average online gift was $71, down $15. And email lists continue to grow, but more slowly.
