When a contact asks you directly to stop sending them emails or texts, you can manually unsubscribe them from their contact record, and re-subscribe them later if they want to opt back in. This is sometimes called a "do not contact", "no contact", "do not email", or "do not text" list.
Contacts can also unsubscribe themselves by clicking the unsubscribe link in a mass email, or by replying "STOP" to a mass text.
How to Manually Unsubscribe a Contact From Mass Emails
Click Contacts.
Search for the contact by name or email address.
Click the contact's name to open their contact record.
In the Details card, find Unsubscribe.
Click Change next to No.
The value changes to Yes, and an Unsubscribed badge appears under the contact's name.
How to Re-Subscribe a Contact to Mass Emails
This is done from the Details card on the contact record.
Open the contact record.
In the Details card, find Unsubscribe.
Click Override next to Yes.
The value changes to No, and the contact will receive your mass emails again. You can also click Override next to User Unsubscribed in the Contact Lists card on the contact record.
How to Opt a Contact Out of Texts or Back In
Text Opt Out applies to texting and is used when you have a texting add-on.
Open the contact record.
In the Details card, find Text Opt Out.
Click Change.
The value switches between No and Yes each time you click Change.
Key Notes
No means the contact will receive your mass communications. Yes means they are opted out.
Unsubscribe applies to mass emails. Text Opt Out applies to texts.
Text Opt Outs are per user. Opting a contact back in lets you text them again.
While a contact is opted out of texts, the Text button on their contact record is disabled.
