Productivity Without E-mail

Over the last two days I have been focusing on prototype of a new Project. In order to ensure that I was not distracted I turned off all interruptions. Everything from e-mail to instant messenger and even my cell phone were turned off so that there were no external distractions at all. To be perfectly honest the last two days have been the most productive days that I have had for a long time. I know that much of my day can be spent sitting in Outlook, meaning that by the end of the day I feel like I have achieved nothing more that add a dozen or more tasks to my To Do list. The last two days have been a liberating experience; I have felt that by cutting the umbilical cord to my inbox I have achieved so much. Looking at the number of unread messages I now have, though, has taken the shine off breaking free.

I sometimes think that e-mail is more of a distraction then a productivity tool. I am a big fan of picking up the phone and calling someone. Often a phone call will only take a few minutes whereas an e-mail conversation can take numerous e-mails to archive the same result. Do you think that e-mail is productivity tool or just another distraction we can often do without?
