Gmail does a good job of preventing spam and when you click the spam button gmail sometimes has a pop-up asking if you want to mark it “spam” or mark it “spam and also unsubscribe”, that must be for sources that gmail recognizes.

I just mark it spam unless it is a company that I know already has that email address.

I also use 2 or 3 extensions that keep emailers from knowing that I opened an email.

You can mark as junk or spam, or filter to your deleted box. The email site can also unsubscribe for you. Usually there’s a link above or below the email. It’s supposed to be safer than clicking on the sender’s own unsubscribe link.

Send them to your SPAM folder instead of unsubscribing.
