In a single opt-in signup process, the customer is added to the CRM as soon as he/she signs up their mobile number to receive communication from you. Since a single opt-in does not require an additional confirmation, it may not assure the required protection regarding TCPA regulations. We highly recommend that you use double opt-in signups to build your contact lists.
