Anytime your donors tell the story of your mission and its impact, you should use it!
Marion Medical Mission apparently monitors its donors email feeds and blog posts. In a brilliant move, noticing a post by one of their donors, they put his post in their regular mail-out.
Fundraising gold nugget: Stories are the currency that fundraisers collect to pay their donors for their gifts.
The donor, Harry T. Jones does a weekly post that he posts on his website and sends to his private email list. His post mentions his trip to help them in their mission and how it affected him. Marion Medical Mission reprinted his post and sent it out through their mailing list.
Catching Harry T.'s story, in his own words and recirculating it is a winning move!
