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.

If you'd like to support aerc development, you can contribute to my Patreon page.
Note: aerc is not done, some of these are planned or in-progress
