Quick verdict
Superhuman Mail is a keyboard-driven email app for Gmail and Outlook accounts, with AI drafting, inbox sorting, reminders and an AI assistant. The company behind it was formerly Grammarly, Inc. Superhuman Mail Starter is $30 a month or $300 a year (the Mail plans page shows $25 per member a month billed annually) and includes Split Inbox, reminders, scheduling, Share Availability, Shared Conversations, Team Comments and most Superhuman AI features, such as Write with AI, Instant Reply and Auto Summarize. Superhuman Business is $40 a month or $396 a year, $33 per member a month billed annually, and adds Ask AI, Auto Drafts, Custom Auto Labels, HubSpot, Salesforce and Pipedrive in the inbox and a Mail MCP server, plus everything in the Superhuman Pro suite plan: Superhuman Go, Grammarly, Docs and Email Assistant inside Gmail and Outlook. Superhuman's plans page showed euro prices from our network, so these US prices come from its help center and Mail plans page; no page we read has a tax note.
On data, Superhuman's privacy policy says training controls in your account settings decide whether your content is used to train its AI models, and the Mail help center adds that neither Mail nor any of its vendors train on your data. No page we read gives a commercial-use statement for AI-drafted emails or describes a data export; you can ask Superhuman by email to delete your data.
One thing to check before you pay: Superhuman's pages describe two Business offers at the same price, a Mail-only Business and the suite Business that includes Grammarly, Go and Docs, and the Mail-only one may lack those. This verdict rests on what Superhuman documents, not on our tests, which we have not run yet.
Strengths and limits
Strengths
- AI writing on both plansWrite with AI drafts emails and, in Editing Mode, can improve writing, fix spelling and grammar, shorten, lengthen, simplify or rewrite in your voice, or follow your own edit prompt. Instant Reply and Auto Summarize are included from Starter, and on mobile you can draft by voice with Write with Voice.
- Ask AI across inbox, calendar and webOn Business, Ask AI finds, writes, schedules and answers questions using your inbox, calendar and the web. It searches email from up to five years ago (excluding Trash and Spam), reads attachments in a thread and keeps a 90-day chat history.
- Many accounts in one appYou can manage as many Gmail or Outlook accounts as you like in the Mail desktop app for Mac and Windows and the iOS and Android apps. Zoom, Google Meet and Microsoft Teams connect for scheduling.
- Business includes the whole suiteThe suite Business plan adds Superhuman Go, with pre-built agents or your own and connectors such as Gmail, Google Calendar and Jira, Grammarly, Docs, and Email Assistant, which brings Auto Labels, Auto Archive, Auto Drafts and Auto Reminders into your existing Gmail or Outlook inbox.
- CRM and AI tool connections on BusinessBusiness puts HubSpot, Salesforce and Pipedrive in the inbox and includes a Mail MCP server that connects Superhuman Mail to Claude, ChatGPT and other AI tools. Neither is available on Starter.
Limits
- No free Mail planPlan limit. Superhuman Mail starts at $30 a month. The suite's Free and Pro plans ($15 a month, or $12 a month billed annually) do not include the Mail app, although Pro includes Email Assistant inside Gmail and Outlook.
- Starter leaves out the assistantPlan limit. Ask AI, Auto Drafts, the Mail MCP server and the HubSpot and Salesforce integrations are Business features. Starter has Write with AI for drafting but no inbox assistant.
- Two Business plans at one priceUnverified point. Superhuman's Mail pricing help page describes a Mail-only Business plan, and the suite FAQ describes a Business plan that also includes Grammarly, Go and Docs, both at $40 a month. If the Mail-only plan is still sold, it may lack those.
- US prices from the help centerUnverified point. The plans page showed euro prices from our network. The US prices come from Superhuman's help center and its Mail plans page, which rendered $25 for Starter and $33 for Business billed annually; we found no tax note.
- Gaps in what is documentedNot verified. Superhuman does not name its AI models or publish usage caps for Mail. Commercial-use terms for AI-drafted emails, a data export and ads are not described, and Word, Excel and Google Sheets support is not stated.

Who it suits
A good fit if you

- Drafting, shortening and fixing emails with AI, from Starter
- Asking questions across your inbox, calendar and the web, on Business

What it documents for each use
- Writing & Content Edit an email without losing a detail · Edit an article without changing its facts · Draft long pieces that stay consistent · Write ads, posts and short copy · Fix grammar and tone in my writing
- Coding & Development Get help with code questions · Diagnose and repair a small program
- Business & Productivity Use AI inside Gmail · Connect AI to the apps I already use · Use AI inside Google Docs · Use AI inside Outlook
A use is listed when at least one plan documents every feature a task needs. Answer quality is a separate question: see below.
Using it day to day
Superhuman Mail is its own app: a desktop app for Mac and Windows and mobile apps for iOS and Android, connected to your Gmail or Outlook accounts, as many as you like. It is built around keyboard shortcuts, Split Inbox, reminders and scheduling, with Share Availability for meetings and Shared Conversations and Team Comments for working with colleagues. Write with AI drafts and edits emails, Instant Reply suggests replies and Auto Summarize condenses threads. Zoom, Google Meet and Microsoft Teams connect for scheduling.
On Business, Ask AI works across your inbox, calendar and the web, Auto Drafts prepares replies and Custom Auto Labels sort mail. The suite adds Email Assistant, which brings Auto Labels, Auto Archive, Auto Drafts and Auto Reminders into your regular Gmail inbox and into new, classic and web Outlook, and Superhuman Go, which works in Google Docs through its Chrome or Edge extension and shows Grammarly suggestions inline. Superhuman publishes no usage caps for Mail or its AI features; Docs have automation quotas.
Privacy, data and ads
Superhuman's privacy policy says you decide whether your content trains its AI models through training controls in your account settings, and the Mail help center says neither Superhuman Mail nor any of its vendors train on your data. We found no description of a self-service data export; Superhuman says you can email it to have your data deleted. Whether Superhuman Mail shows ads is not verified. Ask AI and Auto Drafts read your email, and the Mail MCP server on Business lets other AI tools such as Claude and ChatGPT reach your mailbox, so connect only tools you trust.
Read the vendor's own page: Superhuman privacy and data controls. We make no legal or compliance claim.

- Turn project notes into a report that agrees with itself
- Implement a small specification
- Refactor code without changing what it does
- Make a picture that follows a detailed brief
- Put exact text into a graphic
- Change one thing in a picture and nothing else
- Make a short clip that follows a brief
- Make a song that sings your lyrics exactly
- Read a script with names, numbers and abbreviations
- Design a logo with an exact name
Getting started
- Decide whether you need the Mail app at all: if you want AI sorting and drafts inside your existing Gmail or Outlook, the suite's Pro plan includes Email Assistant without Superhuman Mail.
- For the Mail app, choose Starter ($30 a month or $300 a year) for drafting and inbox tools, or Business ($40 a month or $396 a year) if you want Ask AI, Auto Drafts or CRM integrations.
- Before buying Business, check at checkout that the plan includes Grammarly, Go and Docs, since Superhuman's pages describe two Business offers.
- Open your account settings and set the training controls the way you want before connecting your mail.
- Compare Superhuman with Grammarly, Gemini and other tools on our tools page, and read how we check vendor claims.
