feedletter

Self-hosted service that turns RSS or Atom feeds into email newsletters or Mastodon/Bluesky posts.

Servicefree

feedletter is a self-hosted service that watches RSS or Atom feeds and distributes new items to subscribers as email newsletters, individual alerts, digests, or posts to Mastodon and Bluesky, with subscription and unsubscription handled through its own web API. It is intended for site owners and bloggers who already publish a feed and want to offer readers email or social delivery without building that pipeline themselves. It requires running a Java service with a Postgres database.
