This repository is abandoned in favor of ongoing development on The codebase has been rewritten in Go and is much more stable and useful than what you see here.


aerc is a work in progress asynchronous email client for your terminal. aerc is network-first, and is designed with network-based email protocols in mind. It runs all network code in separate worker threads that don't lock up the UI. Compared to mutt, it's also easier on the network and much faster - it only fetches what it needs.
