Donate to Opt Out: The Secret to Smile Train's 46% Increase in Fundraising

Donate to Opt Out: The Secret to Smile Train's 46% Increase in Fundraising: Before it risked losing a large amount of its contact list, Smile Train did a test campaign with 150,000 households, sending half of the group a letter that said if they donated once to Smile Train, the organization would never ask them to donate again. The response was very promising -- those who received the "once-and-done" letter donated $22,728, while those who received a standard letter donated $13,234.
