21736: Brand Registration Failure: Domain Ownership Could Not Be Verified

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

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

Use an email domain that is clearly linked to the brand (e.g., via website, WHOIS record, or DNS TXT record). Contact Twilio Support if verification should be manually reviewed.
