My procedure with emails is to make a direct decision on first read:
- Junk the sender
- Quickly answer
- Delete the email
- Action to take later (it then becomes a task with an attached date)
I don’t read an email twice anymore. At the end of the reading, the inbox is empty. This method works very well when working mainly from remote device (iphone).
PS: a very useful option in outlook 2007 and 2010 (beta is here) is:
right click on mail folder \ properties \ show number of unread items.
