I'm always worried that the spammer just uses "unsubscribe" as a sign that the email actually got through the spam filter and a human saw it? Aside, I've been having a TON of very similar spam emails getting through Google's spam filter, and even marking them as spam doesn't seem to do anything. It's been going on for months at this point. I'm close to just closing that Gmail account because I have no idea what to do about getting close to 10 spam emails per day straight into my inbox in a way Google seemingly can't fix. It's super obvious spam too. "tHe IRs hs a REFUND for u" level stuff.
