The solution to this mania is simple: only touch each email twice. The first time we open an email, before closing it, answer this question: When does this email require a response? Tagging each email as either “Today” or “This Week” attaches the most important information to each new message, preparing it for the second (and last) time we open it. Of course, for super-urgent, email-me-right-now-type messages, go ahead and respond. Messages that don’t need a response at all should be deleted or archived immediately.
