Another innovative way of prioritizing your email, and it’s again by Gmail. All of us receive a lot of spam that already gets filtered by the Gmail spam engine. This feature is about more important and less important emails. Gmail will learn about your email with time, which emails are more important and which are less important ones. With help of this information, Gmail will show emails in three sections namely Important, Starred and Everything else. The emails that you read more often and reply to will automatically get higher in priority. You can also mention which emails are important and which of them are not.
You good old Inbox is always there if you are not very happy with the priority inbox. This feature works with standard Gmail as well as on Google Apps mail for domains and works pretty good already in its beta. To try out Gmail priority inbox, simply log on to your google mail/Gmail account and look for the red link that says “New Priority Inbox Beta”.
