Superhuman

Superhuman is a premium email client for Gmail and Outlook focused on keyboard-first speed, AI triage, and a structured workflow designed to reach Inbox Zero daily. Acquired by Grammarly in June 2025.

Our take

Superhuman earns its price only if the arithmetic works. At $30-40/month it is the most expensive consumer email client on the market. The payoff — claimed 4+ hours per week saved — requires two conditions: you process enough email that repetitive triage has a real time cost, and you will actually invest in learning keyboard shortcuts. Heavy users — founders, executives, sales professionals processing 100+ messages daily — tend to find genuine value. Casual email users should look elsewhere.

The Grammarly acquisition in June 2025 adds legitimate uncertainty: pricing, feature direction, and product independence could shift under new ownership. Watch that story before committing annually.

What stands out

Keyboard-first navigation. The 100+ shortcuts and Command Palette make it possible to process email entirely without touching a mouse. Users who invest 2-3 weeks building muscle memory report that inbox processing becomes closer to text-editor efficiency than conventional mail navigation.

Auto Drafts and Auto Labels. The October 2025 update made these production-ready: Superhuman drafts replies in your writing voice and labels incoming email by inferred intent. This addresses the most cognitively expensive part of high-volume inbox management.

1-on-1 onboarding. Every plan includes a live session with a Superhuman coach. Most tools at any price do not offer this, and it meaningfully reduces the ramp-up time.

Where it falls short

Provider lock-in is the biggest structural constraint. You must use Gmail, Google Workspace, or Outlook/Microsoft 365. IMAP accounts, iCloud Mail, Yahoo, and self-hosted servers are not supported. The absence of offline mode is a real daily friction point when commuting or on unreliable connections.

Who should pick Superhuman

Pick Superhuman if you are a heavy Gmail or Outlook user, email volume is a genuine bottleneck in your day, and the time-saving claim is plausible. Avoid it for light email use, non-Gmail/Outlook accounts, or if you are not prepared to invest in a keyboard-driven workflow.
