Due to budget constraints? Are you kidding me? With my $8/mo hosting I get like 20 addresses. Seriously, how can they operate with such a basic form of communication? Sure, the phone is there, but the phone leaves 0 paper trail and makes it nearly impossible to communicate to a large audience. Really, I don’t get it. When you set up a mail server it isn’t like it costs money per address. There is a one time investment in the machine. Sure, you may have to add crap to the machine if you’re having a lot of people access it, but the cost of email is soooo minimal.
