I would argue that gmail's filters work quite well.

  I would argue that they work a bit too aggressively and are also not intelligent as one would expect or assume them to be. I only have anecdotes here. I've seen instances where one personal email sent from Gmail's web interface is in the spam folder of the receiver. Sending emails to Google Groups subscribers also doesn't get delivered to the inbox several times (even when the receiver has never marked it as spam). With many people using smartphones to check email, my guess is that only a very small percentage of people still check their spam folders regularly to see if there were any false positives and help train the spam filter (to the extent it's willing to learn). Most people only check their inboxes (and many may not even know about a slam folder), and I'm sure there are billions of harmless and expected emails around the world that just got lost because of these filters.
