List Hygiene — ABCs of Improving Address Quality

Accurate as the address may be with CASS, DPV, AEC, AEC II—and satellite photographs to verify the location and address of a house—if the prospect moves and neglects to tell the list owner, it’s all in vain.

Failure to do so can result in loss of postal discounts for the entire mailing. Expect those requirements to migrate to Standard and Periodical mail in the coming years.
