I am an inbox survivor
Yes, but a short time ago, I was nearly buried alive by my own inbox. Over a span of about 45 days, my inbox went from zero (from the last time I’d just transfered it to my archive without sorting) to 1500 messages, all unsorted. It had gotten out of hand, and there was no hope of taking control of it on my own. Until a friend pointed me to ClearContext. It is based on the ideas behind Getting Things Done and has helped me to get and keep my inbox at a nice daily average of about 10 messages. Definitely a very very useful piece of software!
