Often when you make a charitable donation in response to a direct mail campaign, you’re asked to put a stamp on the prepaid envelope. It’s another way to help the organization save on costs. And for a nonprofit, those savings can add up.
With $72 billion in revenue and 154 billion pieces of mail moved in a year, the U.S. Postal Service deals in the billions. That’s why you sometimes hear people joke that “a few million here and a few million there and pretty soon you are talking about real money” with the USPS.
