Margin Mail

A calm, keyboard-first mail client for Gmail on macOS, Linux, Windows and iPhone, with the parts of HEY and Superhuman worth having and none of the tracking. New senders wait at the door until you let them in; people, newsletters and receipts live in three separate boxes; what you owe and what you need sit in two piles at the foot of the list. Every decision you make is yours, kept beside the mail rather than inside Gmail, and it comes with you if you leave. It is a sibling to margin and Margin Calendar and shares their stack and visual language.

The product is defined in docs/design.md, the features in docs/features.md, the screens in docs/ui.md, the keys in docs/keyboard.md and the settings in docs/settings.md. How it gets built is docs/architecture.md and docs/plan.md, how it ships is docs/release.md, and the research it rests on is in docs/research/. To install it, docs/install.md.
