As messages come in, Gmail automatically flags some of them as important. Gmail uses a variety of signals to predict which messages are important, including the people you email most (if you email Bob a lot, a message from Bob is probably important) and which messages you open and reply to (these are likely more important than the ones you skip over). And as you use Gmail, it will get better at categorising messages for you. You can help it get better by clicking the 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 customise the three inbox sections.)
After lots of internal testing here at Google, as well as with Gmail and Google Apps users at home and at work, we’re ready for more people to try it out. Priority Inbox will be rolling out to all Gmail users, including those of you who use
Google Apps, over the next week or so. Once you see the “New! Priority Inbox" link in the top right corner of your Gmail account (or the new Priority Inbox tab in Gmail Settings), take a look.
