Key features

- Offline-first
- Emails are synced to the device, so you can read, search, compose and organize without an internet connection. Changes sync automatically once you reconnect.
- No AI writing
- Marco does not generate, rewrite, summarize or reply to email with AI. The company presents this as a deliberate choice to keep email a conversation between people.

- Native Apple apps and a web version
- Native apps for Mac, iPhone and iPad with keyboard shortcuts, plus a web version for any modern browser, with sync across devices.
- Search, labels and filters
