Delivery status
Delivery status is the sequence of states a sent message passes through, typically sent, delivered, read, and failed, reported back by the messaging platform.
It is more useful than it looks: a message that is sent but never delivered usually means a wrong number or a blocked account, while delivered-and-never-read across a whole campaign usually means the timing or the content was wrong. A failure comes back with a reason, so you know whether to retry or to stop.
