In almost every mail centre sits a stack of trays filled with mail that never made it to its intended destination and had been returned to the sender. The piles accumulate in remote corners of the shops, largely out of sight. Undelivered material is a challenge for all organisations. This isn’t a new problem. Mailing professionals know all about it.
Ignoring the problem is costly and risky. When organisations finally start analysing the backlog of returned mail, they often discover they’ve repetitively sent documents to the same bad addresses.
