I also empty my inbox each day as suggested by Robert Allan in his book “Getting Things Done.” I have a folder titled AAnswerlater and another one for incubate. I either delete, file, answer immediately, or put it in my answer later file which then goes on my to do list.
Main thing is to not compulsively answer anything- and to call people if it looks like you will be e-mailing back and forth forever.
One other tip…create subject lines that tell people what is in your e-mail, especially on replies.
