SMS Fallback

Learn how the SMS fallback is handled for failed iMessage send requests

The iMessage route also supports graceful fallback for several failure scenarios.

Possible reasons an outbound iMessage may fail:

• The subscriber is not capable of receiving iMessages

• The subscriber has not opted-in via inbound message to the selected Sender Identity

• The Sender Identity has been disabled, blocked, or banned

• Our iMessage route is temporarily unavailable

If any of these failures occur, Mobile Text Alerts will fall back gracefully to SMS to deliver your message. This ensures your subscriber will always receive your message, even if there's an issue using iMessage.
