I don't know they do 800K customers, but they only send out something every 4 or 5 months, and are read only. I would definitely make sure that whatever you use has the option to do several smaller blasts. With 800K customers, there are bound to be a several ISPs with a few thousand recipients, and even more with hundreds. That many identical mailing coming in at once very likely may get her blacklisted at those ISPs.
