I recently worked a major development project and found that the 600+ emails a day were completely paralyzing me, and I knew I wasn't alone. I announced that I was implementing a new policy of "Planned Neglect." Essentially, I said "I will look at emails first thing in the morning and in the evening, no more than thirty minutes each. If you have a crisis that I absolutely must participate in then come see me or call me. You know where I am and you have my numbers. Use them."
