The pitch for the “One Gift” program kinda sounds like “Nice mailbox you got there. Be a shame if we were to continue sending pitches to it with pictures of children with cleft palates.”
I think the schtick is that if you send them a one-time “gift,” they’ll stop sending you the envelopes full of deformed children.
That doesn’t stop those same disturbing photos from appearing in the back of every national magazine (at whose cost?). Also, according to this American Institute of Philanthropy report, the donation doesn’t stop the solicitations.
