A message was not delivered

Work the causes in order — the first four explain the large majority of failures and can be checked from the console in under two minutes.

1. Status — queued, sent, failed or rejected. Each points at a different layer.
2. Consent — a marketing send to an opted-out contact is blocked before dispatch.
3. Sender and template — sender registered for that country, template approved for that category.
4. Window — on WhatsApp, non-template sends outside the 24-hour window are rejected.
5. Escalate — with the message ID and timestamp, support can trace to carrier level.

Reading statuses

*Queued* is a throughput issue. *Sent but never delivered* is usually handset or carrier. *Rejected* is almost always sender, template or consent — a configuration problem on your side.
