Our sources have pointed us to updated CTIA guidelines (http://www.ctia.org) that were released mid July 2016. Please consider:
1. It appears from the guidelines in this handbook, the minimum requirements for including the “Reply STOP to stop” are once a month to each customer. It may make sense to
include it more often, but that appears to be the min. requirement. Bottom line, as long as the customer has “opted-in” in writing and been given detailed information on how to opt-out in the “opt-in” form and the confirmation text, the monthly minimum should suffice.
2. It may make sense to send an initial confirmation text to customers who have “opted-in” to receiving text notifications. This may be required for recurring messages programs.
As always, please have your legal counsel review the above web site and follow his advise for your corporation.
