Yes. Outfound automatically adds to every campaign email:
- a footer with your company name and postal address,
- an unsubscribe link,
- the headers email providers need to show their one-click unsubscribe button.
The footer cannot be removed; it tells the recipient who you are and how to opt out.
The company and address details come from the Email footer section of your sender profile. If they are missing, sending is blocked; complete them on Sending › Sender profiles.
Someone who uses the link gets no more email from that sender domain and is added to Blocked addresses. You don't need to do anything.
