We sent out a postcard promotion that cost $1.50 each. 200 were returned with bad addresses. $300 wasted.
Next step: Pay a temp to clean that list so we don’t waste the same money a second time.
A better idea would have been to spend $125 on labor in advance to avoid $300 in wasted mail.
Here’s an idea: Tie your annual mailing list cleanup to your holiday card mailing. Put someone in charge of collecting AND FIXING the undeliverable addresses.
