I see this in the headers. But there was no option in the MacOS Mail client to unsubscribe. Only the Unsubscribe link in the body of the email.

> But there was no option in the MacOS Mail client to unsubscribe.

The functionality for mail clients to offer an "unsubscribe" button is dependent on there being a "List-Unsubscribe" header in the e-mail with a URL:

* https://datatracker.ietf.org/doc/html/rfc8058

* https://datatracker.ietf.org/doc/html/rfc2369#section-3.2

If the sender does not put one in then that's hardly the mail client's fault.

MacOS should have list unsub support from what I can see: https://support.apple.com/en-gb/guide/mail/mlhld3405766/mac

Dependent on the e-mail sender putting a header with a URL in the message:
