Instant, clear feedback in the app
When a message can’t be sent for one of these reasons, you’ll now see a clear explanation — not just a cryptic error code.
Smart DND tagging to protect your list
We now help you automatically manage contacts that can’t be messaged:
Permanent DND is applied when a number is known to be unreachable long-term, such as:
Replied STOP (21610)
Landline (21635, 30006)
Invalid or non-mobile number (21211, 21614)
Temporary DND is used when the issue might resolve soon, like:
Phone switched off or unreachable temporarily
Carrier-specific delivery issues
This ensures your messages go only to reachable contacts — without you needing to monitor everything manually.
