Gmail introduces Priority Inbox

Gmail recently introduced “Priority Inbox”. It basically puts all the important emails in a separate section at the top of your inbox window.

How Priority Inbox works
In order to predict which messages are important to you, Gmail uses some of the same technology that it uses to weed spam out of your Inbox. If it incorrectly predicts which messages are important you can help train it with the importance buttons just like you can help Gmail’s spam filter by using the Report as spam button.

Automatically determining importance
To predict which of your incoming messages are important, Gmail automatically takes into account a number of signals, including:
Who sent the email (For example, if you email Bob a lot, it’s likely that messages from Bob are important.)
What terms it includes (If you always read messages about soccer, a new message that contains those same soccer words is more likely to be important.)
The actions that help us determine which people/terms are important to you include: replying, using stars, archiving, deleting (Messages you star are probably more important than messages you archive without opening.)
This is all done automatically, and no humans ever read your mail.

Training
Email importance ranking works best for people who receive a lot of email. If you don’t receive tens or hundreds of messages a day (or even if you do!), you can help train Gmail to classify your important messages more accurately using the important and not important buttons. If a certain type of message isn’t getting classified correctly, use the buttons or create a filter.
Using the ‘important’ and ‘not important’ buttons:
Select the misclassified message, and click the “mark as important” or “mark as not important” button. When you mark a message, it will move to the appropriate section. This will help Priority Inbox learn what you care about most.

  • If you correct a large number of messages that Gmail classified incorrectly, the amount of mail that gets categorized as important or unimportant (depending on the mistakes you’re correcting) will decrease within minutes.
  • If you consistently mark a particular sender or mailing list as important or not important, Gmail will adjust to mark that sender as always or never important within a day or so.
