Most of my day at work is spent firing off emails. When things get complex after a few emails on one topic I normally try to call someone because it’s easier that way.
I’m actually a fairly good writer of emails. It’s not the sexiest skill there is, but it’s a good one.
Most of the time I prefer emails because of the ability to edit, but there’s a tone that you can’t replace that comes with being on the phone (still far short of in person).
