The Price of Undeliverable Mail for Online Retailers
Undeliverable mail is mail that cannot be delivered to the recipient because the recipient is not available or has moved and has not provided a forwarding address, or because the address information is inaccurate, incomplete, or illegible. Usually, such correspondence is sent back to the sender, if at all possible. If there is no way to return it, it might be held, disposed of, or handled in accordance with postal rules. Managing undeliverable mail guarantees appropriate mail flow and upholds postal service integrity. https://tinyurl.com/4zh8tzjx
