The Problem with Web Email If you spend most of your day in a terminal or text editor, context switching to a web browser for email feels… wrong. Every time I needed to check email, I'd lose focus.

I wanted something better: Offline access - Read and compose email without internet Keyboard-driven - Never touch the mouse Integrated with Emacs - Stay in my editor Secure - GPG signing with my YubiKey Fast search - Instant full-text search across thousands of messages After some research, I landed on the classic Unix mail stack: mbsync + mu + mu4e.
