Correole

Correole is a minimum feature newsletter in Ruby. Correole subscribes/unsubscribes readers and sends the newsletter.

Correole accepts subscribes/unsubscribes by way of its web API. Readers subscribe by means of a form in your website that makes an Ajax request to the API. Readers unsubscribe by means of an unsubscribe link in the newsletter. The unsubscribe endpoint redirects readers to a given confirmation page in your website.

Correole sends out the newsletter by means of command correole send. Correole tries to send the newsletter to each reader and does not retry or record failures. Correole composes a multipart email for each reader from given templates and RSS feed. Correole includes only new RSS items in the email. Correole determines the RSS items that are new by remembering the items it sent in previous runs. You tell Correole to skip new items (remember items and not send email) by means of command correole purge.
