About Superhuman Mail
Superhuman Mail is a fast email client built around keyboard shortcuts, aimed at people who live in their inbox. It sits on top of Gmail and Microsoft 365 or Outlook accounts and adds a split inbox that separates mail from your team, VIPs and tools, plus snooze, reminders, scheduled sending, read status and AI that drafts replies, summarises threads and answers questions about your mail. The company was acquired by Grammarly in 2025, and the combined business now uses the Superhuman name for a suite that also includes Grammarly, Docs and an AI assistant; Mail is included in the Business plan rather than sold cheaply on its own. It has no free tier, so it costs considerably more than most clients. Apps cover the web, Mac, Windows, iOS and Android. It does not support generic IMAP accounts such as iCloud or Fastmail, which rules it out for many people outside Google and Microsoft.
Best for: Executives and heavy email users on Gmail or Outlook who value speed over price.
