Telnyx 10DLC rejected: Sample messages missing opt-out language
Your Telnyx registration came back rejected and it points to sample messages missing opt-out language. Telnyx did not make that call. Here is what the reason means and exactly how to fix it.
Telnyx showed your A2P 10DLC campaign as rejected, and the reason maps to "Sample messages missing opt-out language". The part that trips people up: Telnyx did not decide this. It submitted your brand and campaign to The Campaign Registry (TCR) and the carriers, they returned the rejection, and Telnyx is relaying it back to you.
That is good news for the fix. Because "Sample messages missing opt-out language" is a carrier and TCR requirement rather than a Telnyx rule, the correction is the same no matter which provider you registered through: At least one sample (typically the first/initial message) must show how recipients stop messages.
Where Telnyx shows this rejection
Telnyx surfaces brand and campaign status in the Mission Control portal under its Messaging / 10DLC area, along with the reason returned for a rejected registration. That reason originates with TCR or the carriers.
Telnyx is the messenger, not the decider
Rejections can happen at the brand level or the campaign level, and they mean different things. A brand-level rejection is usually an identity problem such as an EIN and legal-name mismatch. A campaign-level rejection is usually a messaging problem such as opt-in or sample messages. The Telnyx status tells you which layer failed.
The fix
Include 'Reply STOP to opt out' (or 'Text STOP to unsubscribe') in at least one sample message.
Same rejection, different provider?
The reason is identical no matter who you registered through.
Common questions
Did Telnyx reject my 10DLC campaign for sample messages missing opt-out language?
No. Telnyx submitted your campaign to The Campaign Registry and the carriers, who returned the rejection. Telnyx relays the reason. You resolve the underlying issue and resubmit through Telnyx. The fix here: Include 'Reply STOP to opt out' (or 'Text STOP to unsubscribe') in at least one sample message.
Does every 10DLC sample message need STOP language?
No, but at least one does, typically the first or welcome message. Reviewers want to see that opt-out is present and visible somewhere in your submitted samples.
How do I resubmit after a Telnyx rejection?
Correct the issue, then resubmit the campaign for review through Telnyx. Every resubmission is re-reviewed and re-review typically takes one to four weeks, so fix every problem before you resend rather than resubmitting to test it.
