Dealing with Undeliverable Mail in a Digital World
Any postal item that cannot be delivered to the intended recipient for a number of reasons is considered undeliverable mail. A recipient moving without a forwarding address, an erroneous or incomplete address, a denial of delivery, or insufficient postage are common causes. This kind of mail is typically thrown away, sent back to the sender, or sent to a dead letter office for further processing. Mail is classified as undelivered if postal services are unable to deliver it. They could investigate alternative delivery methods or attempt to redeliver the mail. https://thetulsatimes.com/deli....very-issues-what-are
