My best friend and I recently met up and the conversation somehow shifted to emails. My jaw almost fell to the floor when she told me that 60K unread emails lingered in her inbox. WTF? How does this happen? I currently have 23 emails waiting to be read and that bothers me. Our inboxes are flooded with newsletters, invites, bills, and actual important emails. Knowing which items require immediate action and which can be put on the back burner, will help you tackle tasks on your to-do list a lot quicker. Don't let your inbox get out of control. Here's how to prioritize emails and boost your productivity.
