Superhuman Review (2026): Is Superhuman Mail Worth It?
Superhuman Mail is a keyboard-first email app for Gmail and Outlook, sold on one promise: you will get through email faster. Its fans are very loyal. The complaints are about price, a steep first week, and AI drafts that still need checking.
The short verdict: Superhuman Mail is worth it for someone who processes a heavy inbox every day, learns keyboard shortcuts happily, and will pay for the Business plan, because that is where the drafting AI lives. The catch is that it makes you faster: every draft, reminder and scheduling reply still waits for you to send it. If you would rather hand the inbox and calendar to something that does the work, look at Carly, which runs inside the Gmail or Outlook you already use.
”Superhuman” now means two things
Grammarly acquired Superhuman on July 1, 2025. On October 29, 2025, Grammarly renamed the whole company Superhuman and launched a suite of Grammarly, Coda (now Superhuman Docs), Mail, and a browser assistant called Go. In September 2026 it bought the AI notetaker Fathom too. This review covers Superhuman Mail, the email client; the suite is in our Superhuman AI explainer.

What Superhuman Mail actually does
Speed and triage. Every action has a shortcut. Split Inbox puts mail from your team, VIPs, or tools like Google Docs into separate tabs. Remind Me resurfaces a sent email if nobody replies by a date you pick. Read Statuses show who opened your email and on which device. Snooze, Send Later, Undo Send and Unsubscribe round it out.
AI on every plan. Starter includes Write with AI, Instant Reply, Auto Labels, Auto Archive, Auto Reminders and Auto Summarize. Since December 2025, Write with AI can pull from other emails, insert your team’s availability and research online.
AI on Business only. Auto Drafts writes replies before you open an email. The scheduling version (October 2025) drafts a reply with suggested times and a booking link when someone asks to meet. Ask AI answers questions about your inbox from a sidebar. The Superhuman Mail MCP (April 2026) lets Claude or ChatGPT search, draft, triage and send through Superhuman. Business also adds custom AI labels, Recent Opens, and HubSpot, Salesforce and Pipedrive panels.
Calendar and team features. Share Availability, booking links, shared conversations with comments, shared drafts, and team read statuses.
How good are the drafts now? TechCrunch’s Ivan Mehta tested Auto Drafts in July 2026 and sent some “with little to no editing”, but also wrote that “By default, it often generated a positive response to a pitch, or agreed to a meeting at a post-midnight time.” Superhuman’s co-founder told him 40% of auto-drafts were sent within a day, and 60% of those went out unedited.
What users say about Superhuman
On G2, Superhuman Mail holds a 4.7 average across 1,307 reviews, as syndicated on its AWS Marketplace listing on September 28, 2026. Quotes below are verbatim, from G2, the Hacker News thread on the Grammarly acquisition, and an r/taxpros thread on AI email tools for Outlook.
Where it earns its price
- “Time is money; Superhuman saves me an incredible amount of time on a daily basis.” (G2 reviewer, September 2026)
- “I use it myself and it is by far the best email experience ever created. Is it worth the money? That depends on your needs and work, I guess. CEOs laugh at the cost. Developers might think the price is nuts.” (Hacker News, July 2025)
- “for my day job Superhuman is good for Outlook but I found Shortwave to be incredible! (But works with Gmail not Outlook.)” (r/taxpros, August 2026)
Our read: fans pay for speed and inbox-zero discipline. Whether that is worth $300+ a year depends on how many hours a day you spend in email.
Where people get stuck
- “It was fast, great at triage, the snippets, had a lot going for it. Idk since Grammarly acquired them. It was pricey tho so I didn’t stick with them.” (r/taxpros, August 2026)
- “I will say the learning curve when I first started using it was weirdly hard. You have to learn shortcuts. But once you learn them, it makes such a difference.” (G2 reviewer, September 2026)
- “auto-respond only seems to look at the most recent message in a thread rather than the full context of the conversation.” The same reviewer on the calendar: “I gave up on it after about five to ten minutes of trying to use it.” (G2 reviewer, September 2026)
- “None of their AI or Team features matter to me. I just wanted what they originally set out to build — a super fast, keyboard driven, desktop email client. There are daily paper cut bugs and search issues that have persisted for many years” (Hacker News, July 2025)
- “You can’t cancel by yourself!!! You have to reach out to them and ASK FOR IT!” (G2 reviewer, August 2026, a one-star review)
Our read: price pushes some people out, the first week is work, and the AI is a strong first draft rather than a finished reply. One caveat on the last quote: Superhuman’s help center documents a self-serve route (Cmd+K, then Cancel Subscription), so experiences clearly vary.
Superhuman pricing in 2026
Prices as listed on Superhuman’s Mail plans page on September 28, 2026, per member per month.
| Plan | Billed monthly | Billed annually | What it adds |
|---|---|---|---|
| Starter | $30 | $25 ($300/yr) | Core speed features, Write with AI, auto labels and reminders, calendar, team comments |
| Business | $40 | $33 ($396/yr) | Auto Drafts, Ask AI, Mail MCP, custom AI labels, CRM integrations, Recent Opens |
| Enterprise | Contact sales | Contact sales | SSO, SCIM, advanced admin and security, dedicated success manager |
What the table hides:
- Starter and Business stop at 25 seats, per the plan comparison. Bigger teams go to Enterprise.
- Superhuman advertises 15% off Business for teams of 5+. A five-person Business team on annual billing lists at $1,980 a year before that discount. A solo user on Business pays $480 a year monthly, or $396 annually.
- Two price lists overlap. On the suite pricing page, Mail only appears in the $40 ($33 annual) Business tier, which also bundles Grammarly, Docs and Go. Superhuman’s support FAQ warns that buying suite Business under a different email address means “you will continue to be billed for Mail separately.”
Full breakdown in our Superhuman pricing guide.
Problems and limits
The AI you want is on the pricier plan. Superhuman’s own launch posts list Auto Drafts, Ask AI, “our most powerful Write with AI” and the MCP as Business and Enterprise features. Starter buyers get assisted writing, not the drafting assistant.
It still waits for you. Superhuman describes Auto Drafts for scheduling as “You can simply edit, then send.” Reminders tell you to follow up; they do not follow up. One September 2026 G2 reviewer asked for something Business already sells: “It would be great if the AI could draft responses for me to review and approve.”
Only Gmail and Microsoft 365 accounts. Superhuman Mail only supports Google- or Microsoft 365-hosted accounts, which it reaches through their APIs. An iCloud or generic IMAP inbox will not connect.
A new app to learn. The speed only pays off once shortcuts are muscle memory, and only inside Superhuman’s client.
Superhuman vs Carly
| Superhuman Mail | Carly | |
|---|---|---|
| What it is | An email client you drive faster | An AI executive assistant that does the work for you |
| Where you use it | Superhuman’s own apps | Your existing Gmail or Outlook, by email, text, or on the web |
| Scheduling | Drafts a reply with times and a booking link for you to send | CC Carly on the thread; it finds a time, sends the invite, handles reschedules |
| Inbox work | Drafts, labels and reminders for you to act on | Triages, drafts, replies and follows up in your inbox |
| Automation | MCP so Claude or ChatGPT can drive Mail (Business) | Workflows on triggers: new email, calendar event, form, schedule |
| Apps | HubSpot, Salesforce, Pipedrive (Business) | Thousands of apps, including HubSpot, Salesforce, Slack, Notion and Asana |
| Price | $25 to $40 per member per month | Free Zapier-style workflows; AI agents from $35/month |
Superhuman wins if you enjoy running your inbox and want to do it at top speed. Carly is for people who want less inbox time, not faster inbox time: CC Carly on “let’s find a time next week” and it books the meeting. You can also spin up Email Agents, each with its own address that clients or teammates can email directly, with their own instructions and knowledge files. There is no new client to learn, and it works across multiple Gmail and Outlook accounts at once.

Who should use Superhuman, and who should look elsewhere
Use Superhuman Mail if you:
- Handle hundreds of emails a day and want inbox zero as a daily habit
- Like keyboard shortcuts and will put in a week of retraining
- Will pay for Business, since that is where Auto Drafts and Ask AI live
- Work in sales and want read statuses, Recent Opens and CRM panels in your inbox
Look elsewhere if you:
- Want email and meetings handled for you rather than sped up (Carly or a scheduling link may be the fix)
- Use iCloud or another non-Google, non-Microsoft email host
- Have a team over 25 people and no appetite for an Enterprise contract
- Mostly want AI replies inside your current client, not a new app

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
