Remove global unsubscribe link
We've created new email templates that contain their own unsubscribe link. I'd like to remove the unsubscribe links found in Admin>Email, but if I delete out the text and tokens, I can't save the change - I get an error message: Missing value for 'Unsubscribe HTML'
How do I get around this? I guess I could put something generic without an unsubscribe link in this space just to allow me to save it (e.g. This email was sent to {{lead.Email Address}}), but I'd rather delete this entirely.
Any ideas?
Thanks,
James
