Google will be rolling out the priority inbox today (its not here yet). From the description here it sounds great. It tries to predict which email’s you’ll find high priority and tacks onto the list the inbox items you’ve starred. You can add filters that automatically mark emails as high priority as well. As a result of using the new inbox, Google measured that on average 16% less time was used reading through useless email.
Today, Google will begin rolling out Priority Inbox for Gmail, a new feature for managing massive amounts of e-mail. Your inbox will never be the same again.
