I'm certainly not saying it's right - but it works. Gmail's spam filter (and promotions filter) works with >99% reliability as a user, with really trivial numbers of false positives.

I haven't found this to be true at all. I've probably marked thousands of linkedin messages as spam, but they still land in my inbox occasionally. I also get random e-commerce related spam from sites I've never heard of. The false negative rate is massive on corporate spam that should be trivial to classify I'd think. e.g. some of them literally have some variation of "this is an advertisement" along with unsubscribe links.

Cannot confirm. We get a large number of false positives at our business GMail: Customer requests for quotes, Paypal/Stripe security messages, lots of other important emails go to spam. See e.g. https://github.com/nh2/gmail-spamfilters-paypal-security-messages https://github.com/nh2/gmail-spamfilters-paypal-security-mes... For a while now I suspect that GMail has some bug with its own group email addresses: When somebody sends an email to our GMail group email address team@example.com, it shows up in GMail as "Sombody via team@example.com". Of course, teamexample.com receives both spam and non-spam. I suspect that when we mark spam that comes "via team@example.com", GMail learns that as "things 'via team@example.com' are often Spam", even though info@example.com is a Google Groups email. And by now, everything that comes 'via team@example.com' is marked as Spam. So it seems that when we mark an email that arrived at team@example.com as Spam, Google punishes its own Group email address, instead of the sender.

  For that case you would have to mark the mail as spam in the groups interface, not via the forwarded mail.

    While a possible explanation, that sounds extremely inconvenient, and a silly default. It's Google's own group of my own org. Does it make sense that the spam button would punish my group own email? Also, if I mark it spam in the Groups interface, it's still polluting the inboxes of all my team members where it has already arrived, right? I'd have to tell my team to never use the spam button on obviously spam emails. That doesn't make sense for a business email product!

  I think you can set it to be the other way around and have it be "never mark as spam when via team@example.com" - of course, depending on how much spam it gets that might be worse.
