OK, in case anyone else is in this situation.

One of my clients has 120,000 email campaign maximum (120,000 emails @10,000 per email blast max).

In the middle of a major campaign they were rejected because they exceeded the limit (there contract started in June, 2007 and there is NO WAY they have done 120,000 emails in 4 months!). Here's the issues:

1. No way for marketing to view what is left in their quota. The only way to see what's been mailed is to have admin access to billing information and to wade through all the other billing stuff to find email campaigns.

2. Billing information was flawed. They applied 66,000 emails to the first day of the contract (the client did no emails during that time and there is no way to see where the calculation came from -- no link for example to the actual campaign history) and no way to verify the accuracy of this information (though we know it is wrong).
