kill-the-newsletter is a self-hosted email gateway and converter that transforms email newsletters into Atom feeds. It functions by capturing incoming mail via unique email addresses and republishing the content as structured web feeds.
The system utilizes unique-address routing to identify and sort incoming messages into their respective destinations. It includes embedded control links within the generated feeds, allowing for the modification or removal of feed settings via HTTP requests.
The project covers email-to-feed transformation and the generation of XML based on the Atom syndication format. It manages the state of active feeds through a persistent data store to facilitate content organization within a centralized feed reader.
