Gmail Priority Inbox uses an algorithm to flag messages as important. The tool analyzes whom a person e-mails and chats with most, how often they e-mail people, and which keywords appear frequently in the e-mails they read. See a demo here.
Priority Inbox includes sections for “Important and Unread,” “Starred” and “Everything Else.” But did you know they don’t have to be ordered thus? Google said users can create a section that shows messages from an “Action” or a “To-do” label, add their own fourth section, or change the maximum size of any section.
