AMF - SMTP Traffic and Choosing your ISP

The challange is to find a cheap ISP that allows a considerable deal of SMTP traffic.

Consider a database that has about 2,000 records, memberships will expire, and notification will be sent two months before expiration, one month before expiration, 1 day before expiration, and 1 month after expiration. Doing some simple projections on this, we can expect to have anywhere from 100-400 email notifications sent out daily. Brinkster allows up to 2,500 messages to be sent daily, which is pretty damn good all things considered.

Next is the issue of 'blasting' an email out to a group of individuals. Unfortunately many ISP's, at least the ones I've researched will not allow more than about 75 individuals to receive the same email.

This creates a need for other services, but I guess that's another thing.
