Unsubscribes and the do-not-contact list

Unsubscribes

Every campaign email includes an opt-out line and a one-click unsubscribe link. When someone unsubscribes:

• Their address is blocked across the whole workspace, for every campaign and every member.
• Removing them from the do-not-contact list does not let you email them again. Their opt-out stays.

You can also mark a reply as Unsubscribe in the Inbox to block the address.

Do-not-contact list

Managers and administrators open Workspace settings → Do not contact.

• Add an email address to block one person.
• Add a bare domain (for example example.com) to block a whole company.
• Add an optional reason.
• Paste many entries at once, one per line.

Sending and mailbox drafts are blocked for everything on the list.
