alt Hacker NewsI'm always stunned at how good GMail's spam filtering is, at least for me. I've been using the same email address since 1996 - that's 30 years now - and posting it with absolutely no thought to spam protection all over the place.
I get ~1000 spams per day. About 1-2 end up in inbox. Every so often I do go through my spam, and while it's possible I've missed something, I generally find less than 1 false positive a month and it's never anything especially important.

I've been a Fastmail customer for years and have been pretty happy with their spam filtering too. Anything that does get through either gets a custom rule to send it to the shadow realm, or gets sent to a special "Learn spam" folder that I set up which will train the spam filter on that message.
I've started to question if GMail's spam folder is marketing more than substance. I've used the same primary email address for nearly the same number of decades. The time I saw the "most" spam in a spam folder was only while it was hosted on Google Workspace. Actually trying to skim through those "1000s per day" a lot of them seemed suspect in strange ways (why was this even delivered anywhere?) and some of them even seemed like Google just dumping random ad copy from legitimate search ads into the folder.
(Also it says a lot that right now my two biggest sources of daily spam are Google Calendar Notifications and Random Firebase Accounts. Both of those further leave me questioning if Google's approach to spam filtering is sincere.)
