is an RSS/Atom aggregator with a difference: It allows you to keep track of your feeds through e-mail - you create an OPML file listing your feeds and Newspipe will collect them, convert them to e-mail messages and send them to your mailbox.

This means you can read, organize and archive news feeds using your current mail client (or even webmail), without needing to use a separate program. Newspipe can send you news items as plaintext or HTML mail, both as single items or grouped in a digest.
