The best thing I ever did in Gmail was filter the word "unsubscribe" to skip the inbox and go into a "Newsletters" label. Whenever I peek in there I see nothing but garbage, dozens of emails a day that I wouldn't have cared about. Right now it's sitting at 5,162 unread emails. It keeps my inbox almost always being things that are relevant or interesting.
I've shared this with a few friends who love it. It's pretty flawless. It's never caused me to miss any important emails (that I'm aware of).
