Message delivery is unconfirmed
The provider did not confirm whether it accepted this message. The customer may have received it.
- Code
delivery-unconfirmed
What to do now
- Check whether the customer received the message before using Resend in Inbox. Resend creates a new message and may duplicate one the provider already accepted.
Why this happens
- A timeout, lost connection, or unresolved send left the provider outcome uncertain.
Before you retry
Confirm receipt first
There is no automatic resend for this outcome. Confirm receipt first: Resend creates a new message and may send a duplicate. Later provider confirmation can update the original message status.
