I just published a Rails plugin that allows you to easily build and send Newsletters via Amazon SES (which is very affordable). The name of the gem is aws_ses_newsletters. It uses Sidekiq (because you will usually run the process asynchronously) and Premailer to inline the css. You can find the code here: https://github.com/10Pines/aws_ses_newsletters The readme has detailed instructions to install it and use it. There is also a demo project at: https://github.com/10Pines/aws_ses_newsletters_demo Any feedback will be appreciated!
