Its great for me because I've had my gmail since it started and after a certain point I couldn't keep up with deleting the shit that made it past spam filter so I gave up and just use search to find stuff. I now have overr 30k unread emails in my inbox (that's gonna take some time to clean) but 3 days, not a single unwanted email in my inbox (except for one about Poop, their CEO said the server crashed).
Funny enough, this is the one email that made it through:

Wholehearted recommendation for anyone who has gotten behind in their emails.
