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 Compliance — 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.
