It may be, but it's not my experience. I find that
it depends on people. Some use email a lot. Some
always read it but often don't bother to respond.
Others don't use their email accounts very much.
I'm surprised you'd see that with a company. It
sounds to me like they're either just not on the ball
or for some reason they don't want to bother with
you.
