I made fun of deferring email when I first heard of it. It seemed dishonest and gimmicky. However when I tried it out, I quickly became a believer. There’s a lot of email that can stand be putting off for a little bit of time but isn’t worth the extra work and baggage that come with adding it to your OmniFocus or other task manager database. In that case, deferring email really works.
