Reading all the comments makes me think I'm an outlier. I very aggressively unsubscribe from everything so I get very little mailing list spam. Maybe a few messages a month. What I do get _constantly_ is spam email messages to my inbox from Gmail and Outlook domains. At least one a day for many years. Because it from Gmail, they have very little spam filtering done, yet if any other provider sent these messages then…
Never unsubscribe from anything you haven't subscribed for (or at least where you haven't gave your email address to the sending party), because I believe any interaction with unsolicited emails provide spammers with a clear signal that their spam is not just delivered but also read and interacted with, so they get more agressive.
