* Failure to obtain express end-user consent (opt-in) or respect the end-user’s right to revoke consent (opt-out) will result in carrier rejection of your submission.  Consent cannot be purchased as a list from a third party.  Consent cannot be obtained by virtue of an existing business relationship for other purposes unrelated to text messaging, or from consent given for text messaging of a different use case.  While opt-out functionality is enforced at the Network level through the STOP and UNSTOP keywords, brands must act upon every opt-out event they receive by removing the opted-out consumer phone number from all distribution lists associated with the messaging program.  No future messages may be attempted.
