I have a problem with how to manage sms unsubscribe from a keyword. We have 3 DE for our SMS send in mobile connect, these DE are empowered by automation based on optin filter for every DE (Keyword=optin)
What i don't know is when sending, we attach the DE to the keyword, so is it possible to create a stop keyword for every keyword in order that customer can unsubscribe from our send (Newsletter, Sale...).
And also if the customer use the stop keyword for exemple to unsubscribe from our newsletter, where is updated in mobile connect? and how i can use this to update a optin field in sales cloud field?
