It also blocks just about any small domain that emails me for the first time. No amount of SPF or DKIM will convince Google that you're legitimate party, there's some kind of minimal volume you need to send Google to make your emails arrive to Gmail inboxes the first time.
It works when it works, but when it doesn't, it's broken without repair. It works _most of the time_ and it's better than Outlook (though that's not a high bar to clear).
But now its superb - reporting that a mail is spam does a good job of marking future mails from that sender as spam and moving messages from spam folder to inbox does the opposite.
They’re super obvious ones too with a nonsensical email address, a repeating pattern about mcaffee or Norton in the title and an almost empty body with a pdf attached.
Meanwhile Gmail also happily never learns when I tell it something isn’t spam either.
What? This hasn't been true for at least 15 years. Instead, Google's spam filter is far, far more aggressive than could conceivably be appropriate, and it routinely filters important communications from people you know.
