Fun update: I got tired of disliking every email client I’ve ever used and built my own. It’s called Exo (for exoskeleton). It’s Claude Code for my inbox. It manages my inbox for me, and it’s open source. Link to repo + some notable features in thread!↗

Mailspring is a fast, fully open-source email client for macOS, Windows, and Linux built with Electron. It supports common email workflows including IMAP.↗
