Zappos.com CEO Tony Hsieh has created a personal system to deal with inbox overload. Instead of getting swallowed up in email messages, he is fighting back with a system that is centered on the idea, "Make yesterday's inbox today's to-do list." In a post on LinkedIn, he explained his system which involves responding to yesterday's email today (unless it just can't wait), and setting time to respond to emails that will take more than ten minutes to write in the same way you would set a meeting.
