Some Gmail users are finding a new link in their Gmail interface, for a new beta Gmail service, in which Gmail sorts your email for you, prioritizing it based on which email it thinks you will consider important and “everything else”. The service, called Gmail Priority Inbox, determines which email messages you are likely to find most important, as determined by your previous handling of such messages (based on things like who the email is from, whether you usually open email that’s from them, and if you typically reply to it after opening it), and puts them into an “Important inbox”. Here is more information, as well as the information to undo Priority Inbox (i.e. remove Priority Inbox or deactivate Priority Inbox) if you decide that you don’t like it.
