Operational emails showing unsubscribe option

Hi,

I'm trying to send operational emails without the unsubscribe option - but no matter what I try, all my emails have the unsubscribe option.

I've tried checking the 'Operational email' box on the email. I've sent emails as test emails and as real emails.

Does anyone have any insight into getting rid of the Unsubscribe option for operational emails?

Also, I do not have Admin access.

Thanks a lot!
Ed
