# 30887: Campaign vetting rejection - Opt-out Error

Log Type: APPLICATION

Log Level: ERROR

## Description

Your A2P 10DLC campaign registration was rejected because the opt-out details in the submission do not clearly show how end users can stop receiving messages. If you manage opt-outs yourself, provide `opt_out_keywords` and an `opt_out_message` that acknowledges the opt-out request and confirms that no further messages will be sent.

### Possible causes

* The Call-to-Action or Message Flow does not clearly explain the opt-out process.
* Your campaign indicates that you manage opt-outs yourself, but `opt_out_keywords` were not provided.
* Your campaign indicates that you manage opt-outs yourself, but `opt_out_message` was not provided.
* The `opt_out_message` does not acknowledge the end user's opt-out request.
* The `opt_out_message` does not confirm that no further messages will be sent.
* The opt-out workflow in your submission is incomplete or does not match the way end users actually interact with your campaign.

### Possible solutions

* Update your Call-to-Action and Message Flow so they clearly describe how an end user can opt out.
* If you manage opt-outs yourself, provide every configured value for `opt_out_keywords`, such as STOP, UNSUBSCRIBE, END, QUIT, or HALT when those keywords are supported by your application.
* Add an `opt_out_message` that acknowledges the opt-out request, confirms that no further messages will be sent, and includes your brand name.
* Review your sample messages and consent flow to make sure the opt-out instructions match the real user experience.
* If you use Twilio default opt-out handling or Advanced Opt-Out, use that configuration instead of submitting incomplete custom opt-out fields.
* Resubmit the campaign after updating the opt-out workflow and messaging.
