I really like email. It works well for me. One thing that I grew accustomed to was the abillity to postpone email. To set up quick reminders easily. I used ‘replylater.com’ for this. Unfortunately last month they stopped working for me.
I decided to just implement the same features myself: Mail Me Later works pretty much like replyater.com.
The ‘problem’ is, that once a tool works for me I completely start to rely on it. Having a topic delegated to a service like ‘mail me later’ means that I will entirely forget about it. Good since it saves hassle, really bad if that service fails.
Having this part of me workflow now in an environment where I can quickly verify its operation makes me very happy.
