# 63026: Channel sender content flagged as spam

Log Level: ERROR

## Description

This error indicates that Twilio flagged the sender content in a channel message as spam. Review the message body, consent history, and applicable messaging rules before you send again.

### Possible causes

* The message contains spam-like language, excessive capitalization, or repeated punctuation that can trigger filtering.
* The content is illegal, harmful, unwanted, inappropriate, objectionable, or otherwise prohibited by Twilio Messaging Policy.
* The recipient has not explicitly opted in, or you have not retained proof of consent.
* The message does not follow the applicable country-specific messaging guidelines.
* The message is designed to evade unwanted messaging detection and prevention mechanisms.

### Possible solutions

* Rewrite the message to remove spam triggers and keep the content clear, specific, and relevant.
* Send messages only to recipients who have explicitly opted in, and keep a record of that consent.
* Make sure each message clearly identifies the sender and includes standard opt-out language such as `STOP` when required.
* Review Twilio Messaging Policy and the country-specific rules for the destination before you resend the message.
* If the message is part of an ongoing campaign, use Messaging Insights recommendations to review spam complaints and delivery signals.
