## Description

The domain used in the brand contact email could not be independently verified as belonging to the brand.

### Possible Causes

The domain has no verifiable public ownership records or does not align with the registered brand information.

### Possible Solutions

Use an email domain that is clearly linked to the brand (e.g., via website, WHOIS record, or DNS TXT record). Contact Twilio Support for additional guidance.
