If you write them, it will come
Your final job is to let your donators know how they can help. If you are looking for monetary aid, include a self-addressed, stamped envelope with your letter. If you are trying to organize a group of people, such as for a team to run in a charity race, give your contact information and the times when you’ll be around to receive calls, as well as all the pertinent information (date, time, how long the race is, and where it will take place). Then sit back and start drafting your thank-you letter to everyone who helped you!
