return receipts
Proof of arrival
Return receipts are confirmations that a sent item reached its destination.
For physical mail, a return receipt is a signed card proving delivery: She requested a return receipt for the certified letter.
In email, a return receipt is an automatic notification that the recipient opened the message—though many users decline to send them.
