Superhuman is a paid email client for Gmail and Outlook accounts, designed around keyboard shortcuts, Split Inbox and an AI layer that triages, drafts and summarizes on your behalf. Rahul Vohra started the company back in 2014, and Grammarly acquired it in July 2025. The parent company then rebranded to Superhuman Platform Inc. on October 29, 2025. Starter plans begin at $25/member/month billed annually, with no free tier for Mail. The entire interface, menus and support are in English only.
Every action in Superhuman Mail maps to a key. Archive, reply, snooze, forward, schedule. The first few days feel slower than a regular email client software, because muscle memory has to build. Once it clicks, the speed gap becomes obvious. G2 reviewers (4.7/5 across 1,300+ reviews) almost universally cite shortcuts as the feature that hooks them.
Split Inbox lets you carve the inbox into custom tabs. Separate your team, VIPs, tool notifications from Google Docs or Asana, and bulk newsletters. Even on a flooded Monday morning, the threads that matter stay one tab away.
On the AI side, Starter includes Write with AI, Auto Labels, Auto Archive and Auto Summarize. Business unlocks Auto Drafts, Ask AI, the Superhuman Mail MCP server, plus HubSpot and Salesforce integrations.
Grammarly announced the acquisition of Superhuman Mail in July 2025. On October 29, 2025, the parent company officially rebranded to Superhuman Platform Inc. and launched Superhuman Go, an AI assistant built into the Grammarly browser extension. Coda, acquired in late 2024, became Superhuman Docs. The combined group reports over 40 million daily active users across all products.
Superhuman Mail still operates as a standalone product. Notion Mail, Missive and Perplexity Email Assistant each carve a different niche among AI-powered email tools. The Reddit consensus places the value threshold at roughly 100 emails per day. Below that, the cost-per-message math tilts against Superhuman.
The Business plan also bundles Grammarly, Docs and Go. Starter and Business are capped at 25 seats. Student and nonprofit discounts exist but pricing is not published. The official plans page remains the most reliable source, as these figures can change.
| Plan | Annual billing | Monthly billing | Advanced AI |
|---|---|---|---|
| Starter | $25/member/mo | $30/member/mo | Write with AI, Auto Labels, Auto Archive |
| Business | $33/member/mo | $40/member/mo | + Auto Drafts, Ask AI, MCP, HubSpot/Salesforce |
| Enterprise | Custom | Custom | + SSO, BYOK, priority support |
Superhuman Mail is a paid, keyboard-first email app for Gmail and Outlook. It combines Split Inbox, follow-up reminders, read statuses, AI-powered drafting and triage to help heavy email processors reach inbox zero faster. The app runs on Mac, Windows, web, iOS and Android, and it earned a 4.7/5 rating on G2 across more than 1,300 reviews.
Starter costs $25 per member per month billed annually ($30 month-to-month). Business runs $33 per member per month annually ($40 month-to-month). Enterprise pricing is custom. The Business plan also bundles Grammarly, Docs and Go alongside Mail. Starter and Business cap at 25 seats each.
No. The Superhuman suite has a free tier that includes Grammarly, Docs and Go, but Mail is excluded. To access Superhuman Mail, the minimum is the Starter plan at $25/month billed annually. Student and nonprofit discounts exist, though exact amounts are not published.
Sort of. Grammarly announced the acquisition of the Superhuman email client in July 2025. Then on October 29, 2025, the parent company renamed itself Superhuman Platform Inc. The Grammarly writing product keeps its own name. So Superhuman Mail and Grammarly are sibling products under the same corporate umbrella, alongside Superhuman Docs and Superhuman Go.
Verdict: Processing a heavy inbox at keyboard speed, auto-drafting replies in your own tone and never missing a follow-up again: that is what Superhuman Mail delivers. Founders, sales teams and executives who handle 100+ emails daily will recoup the $25-to-$33 monthly cost in saved hours, provided they commit to the shortcut learning curve.
