Yeah, use `List-Unsubscribe`. Has the additional advantage that I don't need to find the "unsubscribe" link at the bottom of some bloaty HTML, works across languages etc.

If the email scanner of your recipient insists on clicking "unsubscribe" on their behalf without that being the desired outcome, that's not on you to prevent them from.

I mean if your unsubscribe link unsubscribes someone just because Microsoft Email Phishing for Copilot visited the link to see if it was a Virus, then you need to “get gud” as the kids say.
