Not to discount the anti-spam algorithms. I religiously mark spam emails as spam. Gmail is quick at learning. 90% of my email is promotions which I never look at. I just hope gmail had an auto unsubscribe. Most of the time unsubscribe doesn’t work since sites require humans to click some button or entire their email again. I am far more worried about real mail spam. Can I do something about that ?
