I need a total email system for my web application.
- Newsletter delivery once per month.
- Notifications when a user has registered with the web app or performed an action within it.
There will be approx 200,000 subscribers to the newsletter running over a period of 4 months sending 1 email per month.
There will be approx 500,000 notification emails sent over the 4 months.
Currently my web app infrastructure is based around a load balanced system which makes it difficult to send the notification emails reliably regarding reverse DNS... is there a clever way around this?
I'm looking at Campaign Monitor for the newsletter management and postmarkapp for the notification emails but pricing seems quite expensive. Is there a service which can combine both of these requirements? Or any other recommendations?
