Google rolls out a new Gmail feature "Priority Inbox" that figures out which of your messages are important, and presents them in sorted form at the top of the screen. In short, it's like your personal assistant, helping you focus on the messages that matter without requiring you to set up complex rules. Priority Inbox splits your inbox into three sections: "Important and unread," "Starred" and "Everything else".
Once it's activated under Settings, you'll see a prompt asking you if you want to enable Priority Inbox. You can choose from a few options (the order of your various inboxes and if there're any contacts you'd like to always mark "Important"), that's it.
Gmail automatically flags some of them as important. Gmail uses a variety of signals to predict which messages are important, including people you email most and which messages you open and reply to. And as you use Gmail, it'll get better at categorizing messages for you. You can help it get better by clicking the or buttons at the top of the inbox to correctly mark a conversation as important or not important. You can even set up filters to always mark certain things important or unimportant, or rearrange and customize the three inbox sections.
Over next week, Google’ll be rolling out Priority Inbox settings to users in organizations with “Enable pre-release features” option selected in Google Apps control panel.
