This cant be right (but if it is, they're morons). In this scenario, we'll need a package for millions of members. With the rough math I just did, this would make our monthly Mailchimp bill a larger cost for us than our AWS accounts monthly cost. That would be insane...
Mailchimp, PLEASE CLEAR THIS UP ASAP. YOU'RE FUCKING WITH MY LIFE AND I DON'T LIKE IT OR NEED IT!
