The `Do Not SMS` checkbox will then be checked on John Doe’s Contact record. When the `Do Not SMS` checkbox is checked on a record, Blackthorn Messaging will not let you send a message to that record. The first image below shows a Contact where the `Do Not SMS` checkbox is checked. The second image shows the message that will be displayed when you attempt to send a message to that Contact. ![manage optouts_1](https://cdn.document360.io/f977eec0-500f-40a3-b663-724a51f78075/Images/Documentation/manage%20optouts_1.png) --- ![manage optouts_2](https://cdn.document360.io/f977eec0-500f-40a3-b663-724a51f78075/Images/Documentation/manage%20optouts_2.png) ## Bulk Messaging When you send a bulk message or a campaign message, any records that have the `Do Not SMS` checkbox checked will be skipped and no message will be sent to those records.
