Somewhat interesting history of the mail, telegrams, etc. but I got bored with it -- too long? too discursive? Not sure, just decided to cut to the end to the recommendations.1. Don't send. Send less and less email, especially social. It cuts down on the cycle of email, and less email will come back to you as a result.2. Don't check it first thing in the morning or late at night. He's really talking here about the boundary between work and private life -- assuming that you are checking your work email.3. Check it twice a day -- or even just once an hour. Especially if you have a backlog. But all the backlog in a file folder and allot some time each day for dealing with the backlog, being ruthless of course.4. Keep a written to-do list and incorporate email into it. Answer newly received emails with a timeframe -- it's going to take me a day or two to get back to you on this. . . 5. Give good e-mail. Short messages, good subject lines. Think the message through and make sure it's complete, rather than having to add a follow-on email immediately afterwards.6. Read the entire email before responding.7. Do not debate complex or sensitive matters by email.8. If you have to work as a group by email, meet your correspondents face-to-face.9. Set your desk up to do something else besides email.10. Schedule media-free time every day.
