Can I use one of your shared hosting accounts purely for bulk mailings?

NO, Not at all.

Unfortunately, our accounts were not created or meant for purely bulk mailings. While our users benefit from the luxury of being able to send out newsletters and similar mailings to their visitors/customers, we are not a bulk mailing/mailer service and do not allow such activity to take place on our PersonalClass or BusinessClass services. If our DedicatedClass is within your budget, please contact our sales department.
