The productivity research I’m reading keeps stating that an open email box with notifications turned on is the nemesis of productivity - it takes a full 4 minutes to re-enter what you were doing and up to 20 minutes to reenter a flow state. This Chrome extension may make a happy medium and lets you pause your email if your company REQUIRES you to keep email open. I think that companies should rather encourage checking at certain times during the day. Often, email is a time waster and there are those who specialize in e-procrastination. Like those who wait to see you walk out the door before hitting send. ;-)
