To maintain carrier compliance and make SMS recipients happier, Ytel has expanded our opt-out service to include local and toll-free numbers to an outbound opt-out auto-messaging service.
When an SMS recipient response back with the single opt-out word, STOP, END, QUIT, CANCEL or UNSUBSCRIBE to the shortcode, local number or toll-free number that originated the message, the recipient's number will be sent an opt-out message and added to the DNC list. Future contact with that number will be blocked. (The opt-out word must be the only word in the message. They are not case sensitive). Ytel does provide the ability to create your own customer opt-out keywords. More information on how to set up a custom opt-out keyword by viewing the Compliance documentation.
These keyword opt-out messages cannot be changed or removed and the opt-out message the end-user receives cannot be changed. However, if you are using our Campaign API to send out your SMS, you have the ability to add additional opt-out keywords within your portal. Please see the Campaigns guide for more information.
You will be charged for the initial opt-out message at your current outbound rate. If you continue to send messages to numbers on your DNC list, Ytel will block those messages and you will not be charged for the outbound message. You will receive an error code along with an error message stating the contact has unsubscribed.
We highly recommend that you maintain your own DNC list to reduce unnecessary error messages. For compliance place the phrase "Reply STOP to Cancel" at the end of your SMS messaging.
