Maryland Food Bank retains new donors by asking them to give again — before the window of opportunity closes.

By Amy Syracuse

The thank-you letter is mailed in a No. 10 window envelope with a Maryland Food Bank return address. For donations in excess of $100, the letter is sent in a closed-face envelope. And donors who give $500 or more, whether acquisition or renewals, receive a printed letter that includes a handwritten note from Flateman.
