Rated 5 out of 5 stars
Email conversations can be distracting and a waste of time if people reply too quickly.
So I use SendLater to queue up and delay my outgoing emails so that others won't respond to them too soon. Especially with people who send too much email, I email them with a 2 hour delay so that I won't have to deal with their reply for at least 2 hours. It's awesome!
