Regulations and best practices for SMS messages are governed by the Mobile Marketing Association, which publishes a code of conduct and a best practices guide for use by those involved in mobile messaging activities. Ultimately, all SMS messages sent using the ExactTarget application must include the following elements.
Your SMS messages must include a double opt-in process, where the subscriber confirms twice that they wish to receive SMS messages from you. For example, an MO JOIN message would prompt the following MT reply:
Reply YES to receive Example.com Sales. 1 or more msgs/day 4 desired alerts. Reply STOP 2 end. HELP 4 info. Msg&Data Rates May Apply.
From there, a MO YES message would prompt the following MT reply:
Your 1st alert will arrive soon. Reply STOP to end, Help 4 info. Msg&Data Rates May Apply.
Your SMS messages must include a single opt-out process that immediately discontinues sales and marketing SMS messages to a subscriber. For example, a MO STOP message would prompt the following MT reply:
You have opted out of future Example.com alert msgs. For more information reply HELP or visit http://www.exacttarget.com/mobilealerts
Your SMS messages must include a HELP message with the following information:
For example, an MO HELP request would prompt the following MT message:
For more info: http://www.example.com/mobilealerts, email: help@example.com or call 1.866.555.1111. Reply STOP to stop. Msg&data rates may apply.
