What is Marco?
Marco is an email client for macOS, iOS and the web that brings Gmail, Outlook, Yahoo, iCloud and other IMAP accounts into one inbox. It is built offline-first, syncing mail to the device so it can be read, searched and written without a connection, and it deliberately leaves out AI drafting, summaries and replies. Marco Technology Inc. offers it free, with a paid Pro plan announced but not yet available.
Marco is free to use. See every plan
