To begin, go to People (CRM) >> View Everyone >> then search for and select the user you’re unsubscribing from mass communications.
Next, select Edit User >> then check Yes for the method of mass communication they’re unsubscribing from, which are Mass Email, Mass Text, or you can check both as needed. Click Save to complete the process.
If, at any point, the user wants to resubscribe you can go through the previous steps again and select “No” for the method of mass communication they’re resubscribing to.
*Please note that users who ask to resubscribe to text will need to reply “Yes” to a previous text they received from you.*
