Sign up for someone like MailChimp or AWeber or Constant Contact and tie into their API. Emailing at volume can be a bitch, so follow in marketer's footsteps and go with a 3rd party. You can be up and running in a day with analytics.

We're using Campaign Monitor and its faaaar too expensive. Sending 40k/mo would cost over $400/mo and thats ridiculous for email. Mailchimp and others cost pretty much the same.

Are you sending to 40,000 different email addresses or sending a total of 40,000 emails per month? If you are sending to 10,000 addresses 4 times a month (for example) then take a look at iContact. 10,000 subscribers 6x a month would cost $74 a month.

Well, that's $0.01 an email. You should probably be evaluating your conversion rates and ROI, because that's a pretty good rate.

Plus, setting up and maintaining a non-blacklisted, high deliverability mail server is nearly a full time job, so in my opinion $400 is a steal
