Last I checked LinkedIn doesn't even have a way of straight up turning all emails off. I had to individually turn off email notifications on bazillion categories. ...Then they just invented more categories.
Heh that button is sacrosanct for me. If capitalism goaded me into signing up for LinkedIn, and thus fully cognizant agreeing with the site’s ToS, I’mma unsubscribe when I don’t like their mailings.
But if that unsubscribe request gets ignored? Going HAM clicking Spam. Also I won’t touch phishing emails on mobile so I can click Report Phishing from desktop (thanks Gmail).
