Airmail

Airmail is the native iOS and macOS email client built by Bloop SRL, a small Italian software company, launched in 2013. It grew to $3M+ ARR by targeting email power users who found Apple Mail too basic and Microsoft Outlook too bloated — people who process hundreds of emails per day and need keyboard shortcuts, custom swipe gestures, advanced filtering rules, and the ability to connect any email provider (Gmail, Outlook, iCloud, Yahoo, Exchange, IMAP) in one unified inbox. Airmail's integration with third-party productivity tools (Things, OmniFocus, Todoist, Fantastical, Notion, Evernote) via direct deep links set it apart from Apple Mail: you can file an email directly to OmniFocus as a task, or to Notion as a note, without leaving the email client. The custom actions feature (define your own swipe gestures and toolbar buttons) turned Airmail into a personal email processing machine adapted to each user's workflow. The small Italian team's consistent quality updates across 10+ years of macOS and iOS evolution made it a trusted recommendation in productivity circles.
