How can I add an unsubscribe url?
All emails must contain an unsubscribe link when they are sent by Bento. We'll enforce it at the last stage of sending a broadcast.
Do add an unsubscribe link just add the following liquid to your emails.
{{ visitor.unsubscribe_url | hyperlink: "Unsubscribe" }}
{{ visitor.unsubscribe_url | button: "Unsubscribe" }}
Or manually create a link with {{ visitor.unsubscribe_url }} as the URL.
