Fast where it counts.
Tachy means fast. Mail opens from local storage without waiting for the network. Changes apply locally first, then sync.
Your mail, your keys.
Use IMAP on your Mac. Proton Mail can connect through Proton Mail Bridge. Navigate with j and k, open the command palette with Cmd+K, and keep your hands on the keyboard.
Tracking pixels are never downloaded. Other remote images are fetched on arrival rather than when you open a message.
