Using Rails with SES, SNS and SQS to avoid bounce rate
Amazon Simple Email Service (SES) is a cost-effective email service provided by AWS. It is by far the cheapest option available out there. Comparing the cost of sending emails with SES and other services like SendGrid or Mailchimp, it can be 100x cheaper. However there is a catch. Using SES directly, you will not get some of the features you might need to control the bounce rate of your emails.
