Toll-Free phone number verification unable to process - email invalid

Twilio is unable to process your Toll Free Verification request because it could not be validated by Twilio and could not be submitted for verification review.

The toll-free phone number cannot be verified because the email address is invalid. It could be due to:

• Incorrectly formatted email address
• Unknown email domain
• Email is a suspected disposable address
• Email is invalid

Correct the email address and resubmit the verification in Console via the Messaging Compliance API.
