Google now uses an artificial neural network to fight spam. This is the same artificial intelligence developed for Google Search and Google Now to fight spam. The Gmail Postmaster Tools help qualified high-volume senders analyze their email, including data on delivery errors, spam reports, and reputation. This way they can diagnose any hiccups, study best practices, and help Gmail route their messages to the right place.
