"An app for sending millions of emails as cheaply as possible. Mail for Good uses AWS Simple Email Service to send bulk emails at $0.10 per 1000 emails.
Mail for Good is fast and memory efficient, currently sending over 100 emails per second on a 1gb Digital Ocean VPS.
We've used Mail for Good to deliver newsletters to hundreds of thousands of campers per week."
Be even nicer if it worked with Elastic Email too.
