undelivered mail
Letters never received
Undelivered mail is postal matter that failed to reach its intended recipient—returned for insufficient postage, wrong address, or addressee unknown.
Post offices hold undelivered mail for a period before returning it to sender or disposing of it.
The term extends to email that bounces back: I got a notice that my message was undelivered mail.
