The fastest email client ever made, with Split Inbox and best-in-class integrations—but at $25–$40/month it only pays off for heavy Mac users.

Here is the short version up front. The fastest email client ever made, with Split Inbox and best-in-class integrations—but at $25–$40/month it only pays off for heavy Mac users. On pricing, the short version: Starter | $25/mo annual ($300/yr) or $30 monthly | Core features: Split Inbox, AI, shortcuts, snooze, integrations
Business | $33/mo annual ($396/yr) or $40 monthly | Everything in Starter + CRM integrations (Salesforce/HubSpot/Pipedrive), Shared Conversations, Team Comments
Enterprise | Custom pricing | Everything in Business + SSO, advanced security, dedicated customer success The current overall score is 4.3/5. Every number here comes from the live site or aggregator-reported ratings, not a vendor deck, so you can decide in one read whether it is worth the trial.

The Short Version

Let’s cut to the chase: Superhuman isn’t “just another email app.” It’s the fastest one you can use today—period. Fire up an inbox with 10,000 messages and scrolling stays buttery, and the hundred-plus keyboard shortcuts flow so naturally you’ll forget your mouse is even there. Split Inbox also separates team mail, VIPs, and tool notifications on its own, so your inbox stays clean without manual triage.

In 2026, it’s not just a solo tool anymore. Shared Conversations, Team Comments, and CRM hooks into Salesforce, HubSpot, and Pipedrive mean small teams can run on it too. But at $25–$33 a month, it isn’t cheap. Under 50 emails a day? Save your money. Heavy user? It pays for itself.

One quick note on the company: Grammarly announced it was acquiring Superhuman back in July 2025, and by October the parent company had rebranded as Superhuman. The email app itself is now officially Superhuman Mail, sitting alongside Grammarly and Coda in the Superhuman Suite.

📋 How we tested: We put Superhuman’s 7-day free trial through its paces on a real Mac, handling 100+ emails a day. We stress-tested Split Inbox, the AI features, and the integrations sidebar, and sat through the full 30-minute concierge onboarding.

Who This Is For (and Who Should Skip)

Match yourself to the product before you sign up.

  • ✅ Keyboard-driven power users handling 100+ emails a day. That’s the sweet spot on Mac, Windows, iOS, and Android—you want raw speed and don’t mind spending a week learning the shortcuts.
  • ✅ Teams already living in Slack, Notion, Linear, and Figma. The sidebar pulls info from those tools right into your inbox, no app-switching required.
  • ✅ Small teams that need lightweight collaboration. Shared Conversations and Team Comments handle most of what small teams actually need.
  • ❌ Anyone who wants a free or cheap client. There’s no free plan—Starter starts at $25/month. If you need free, Spark makes more sense.
  • ❌ Anyone getting under 50 emails a day. The math just doesn’t work at that volume.
  • ❌ Large teams needing a full shared inbox, assignment, and internal chat. Use Missive or Front instead.

What Actually Matters: Features, Reviewed

Superhuman’s Split Inbox divides mail into Important, Calendar, Docs and Other tabs.

⚡ Speed — the reason it exists

Superhuman preloads everything into a local index, so actions never wait on the network. Hit e to archive and the message vanishes instantly—no “saving” spinner. Every operation responds in under 100 milliseconds. ‘Fast’ is the most-cited word on aggregator-reviewed product pages, and after two weeks of our own testing? We agree. Nothing else comes close.

🗂 Split Inbox — the 2026 headline feature

Split Inbox automatically sorts your inbox into tabs: Team (coworkers), VIP (people you’ve flagged), Tools (notifications from Google Docs, Notion, Asana, Figma, Jira, GitHub), and Everything else. Heavy users nearly unanimous that it kills manual sorting. But the price still draws fire—one Capterra reviewer called it “a bit expensive considering it is basically a front-end for Gmail.”

⌨ Keyboard shortcuts — once you learn them, the mouse retires

More than 100 shortcuts. We spent a week learning them and it paid off: e archive, r reply, ⌘+Enter send, h snooze, g i jump to inbox, ⌘+k for universal search across mail, contacts, calendar, and docs. The learning curve is real—new users consistently say the first couple of weeks feel like “too much to memorize,” and many only stop clicking after the 30-minute onboarding session.

🤖 AI — not a toy, it actually saves time

Superhuman’s AI is built right in. In 2026, you get Auto Summarize for long threads, Instant Reply suggestions, Ask AI for thread-specific questions, Auto Labels, Auto Drafts (a draft is ready the moment an email lands), and Auto Archive for marketing and cold emails. Real users praise the speed and clean design most. But some note that deeper CRM integrations sit behind the Business tier—Starter users say the integration list feels “selective rather than comprehensive.”

👥 Team features — new in 2026, lightweight by design

Superhuman now ships Shared Conversations, Team Comments, Team Knowledge (a shared wiki), and Read Statuses. These are add-ons to a personal-first product, not a native collaboration suite. Missive still owns the full shared-inbox, task-assignment, internal-chat workflow. Superhuman’s team layer works for small teams—a 20+ person support team will outgrow it fast.

🔗 CRM & integrations — the strongest sidebar in the game

The sidebar shows Slack status, upcoming Calendar meetings, related Notion docs, Linear issues, Figma comments, GitHub PRs, and Calendly links—all without leaving your inbox. Business tier adds Salesforce, HubSpot, and Pipedrive panes, so you can see deal stage and next meeting while composing. Sales users on Business say this is the single biggest reason they upgraded. The catch? Those CRM panes only exist on Business ($33/mo), which feeds the “expensive” complaint.

What Real Users Actually Say

Superhuman has a large footprint of speed-focused email reviews, but the G2 and Capterra product pages block automated access, so I am working from aggregator-reported figures rather than live pulls and I have not quoted individual reviewers I could not verify.

The Aggregate Scores

Third-party trackers broadly place Superhuman in the upper tier of premium email clients, with aggregator-reported scores clustered around the low-to-mid 4s out of 5. Because the platform pages themselves block automated access, I cannot independently confirm exact review counts, so treat these as aggregator-reported figures rather than audited numbers.

The Recurring Criticism

The praise centers on raw speed, the integrations sidebar, and the way Split Inbox removes manual triage. The complaints cluster in two places I also hit hands-on: the price tag, and the 100+ shortcut learning curve. A smaller thread notes that the Windows and Android apps are newer and less polished than the long-mature Mac and iOS builds, and that deeper CRM integrations are gated behind the Business tier. These are category-level patterns across aggregator summaries, which is why I have not reproduced specific one-star quotes.

Read the split correctly. The high scores reflect a genuinely fast, beautifully engineered client, not a cheap one. If your priority is a blazing inbox at high email volume, you land in the happy cohort; if you’re under 50 emails a day or need a full team shared inbox, treat those as the real reasons to run the 7-day trial before committing.

Pricing (and who should pick which tier)

Superhuman offers a 7-day free trial. After that, two main tiers (Enterprise is custom-priced):

Plan Price What You Get
Starter $25/mo annual ($300/yr) or $30 monthly Core features: Split Inbox, AI, shortcuts, snooze, integrations
Business $33/mo annual ($396/yr) or $40 monthly Everything in Starter + CRM integrations (Salesforce/HubSpot/Pipedrive), Shared Conversations, Team Comments
Enterprise Custom pricing Everything in Business + SSO, advanced security, dedicated customer success

Honest math: one person on Starter pays $300 a year. A five-person team on Business pays $33 × 5 × 12 = $1,980 a year. For comparison, Missive Starter for five runs about $840 a year. Superhuman’s team features are lightweight—if you need a real shared inbox with assignment and internal chat, Missive or Front is the better spend.

Frequently Asked Questions

What’s the difference between Superhuman and Missive?

Superhuman is faster, has stronger Split Inbox, and deeper personal-tool integrations. Missive has a native shared inbox, task assignment, and internal chat. Solo power users go for Superhuman; teams go for Missive.

What platforms does Superhuman Mail support?

It runs natively on Mac, Windows, iOS, and Android, plus a Chrome web app, on top of your existing Gmail or Outlook account. The Mac and iOS builds are the most mature; Windows and Android are newer.

Is the AI included in every plan?

Core AI (Auto Summarize, Instant Reply) comes with Starter. Advanced AI (Auto Drafts, Auto Labels) and CRM integrations need Business.

Why is Superhuman so expensive? Is it worth it?

Pricing complaints are the single most common feedback on G2 and Capterra. Whether it’s worth it comes down to volume. Heavy users (100+ emails a day) almost universally say the time saved justifies it. People under 50 a day say it doesn’t.

Is there a free trial?

Yes—a 7-day free trial of Starter, which includes the 30-minute concierge onboarding to help you set up shortcuts and Split Inbox.

What is Superhuman’s Split Inbox?

Split Inbox automatically sorts your inbox into tabs instead of making you file by hand: Team (coworkers), VIP (people you’ve flagged), Tools (notifications from Google Docs, Notion, Asana, Figma, Jira, and GitHub), and Everything else. It’s the headline 2026 feature, and heavy users on G2 are nearly unanimous that it removes the manual triage step.

How is Superhuman different from HEY?

Superhuman runs on your existing Gmail or Outlook address and is built for raw speed and keyboard triage. HEY is an email service, not a client: it forces a fresh @hey.com address (no IMAP or POP) and rebuilds the whole inbox around a first-time-sender Screener. Pick Superhuman if you want to keep your current inbox and move fast; pick HEY if you want an opinionated inbox reset and a brand-new address.

What is the Superhuman bundle?

After Grammarly acquired Superhuman in 2025 and rebranded the parent company as Superhuman, the email app became part of the Superhuman Suite — one subscription that bundles Superhuman Mail together with Grammarly, Coda (Docs), and Superhuman Go. You can choose which parts of the bundle you actually use; the free and $12/month Pro tiers cover Grammarly, Coda, and Go, while Superhuman Mail itself lives on the Business and Enterprise tiers.
