How Gmail decides which emails are important

Gmail uses several signals to decide which messages to automatically mark as important, including:

Whom you email, and how often you email them
Which emails you open
Which emails you reply to
Keywords that are in emails you usually read
Which emails you star, archive, or delete

To see why an email was marked as important, hover over the importance marker .

Note: If an email was marked as important but you don't want it to be, click the importance marker to change it. This also helps Gmail learn which emails you think are important.

See your important emails

Next to emails that Gmail thinks is important, you'll see a yellow Importance marker . If an email hasn't been marked as important, the marker will be empty.

To see all your emails that are marked as important, search Gmail for is:important.
