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

By Amy Syracuse

The package includes a No. 6¾ closed-face return envelope. The return envelope is preaddressed to Maryland Food Bank in handwriting and bears a return label with the donor’s name and address.

These two pieces are mailed in a closed-face, baronial carrier envelope with First Class postage. The outer envelope does not include a return address; the donor’s name, address, city, state and ZIP code are handwritten on the outside.
