Having recently been on vacation and traveling, the pain of a number of days away from the email box is still fresh. So, when I came across this I desperately wished many of my correspondents had deployed the method.
E-mail takes too long to respond to, resulting in continuous inbox overflow for those who receive a lot of it.
Treat all email responses like SMS text messages, using a set number of letters per response. Since it’s too hard to count letters, we count sentences instead.
three.sentenc.es is a personal policy that all email responses regardless of recipient or subject will be three sentences or less. It’s that simple.'
They also have 2, 4 and 5 sentence versions, which I didn't totally get, but I really liked the 3 sentence idea. You can say a lot in three sentences. I just did.
(sorry, couldn't resist.)
