Email Limit and a Mailing LIst

We have an email list that goes through our domains, which are hosted by MyHosting. I tried running it as a test a few months ago and it stopped after 250 emails had been sent. Can this cap be lifted? It's for a theater project we run. See We are in pre-production for our latest project, Water, Inc.
