Why do you need to do this? Are you hyperactive? Do you think normal people like to do this every 2.603 seconds? I can tell you: they don't. They write one e-mail, and are dedicated to finish it. They, in general, don't want distractions such as "oh, my daughter just send me an IM" or "perhaps Joe is on IRC". Or at least want to keep the temptation to the minimum.
