What is Superhuman?
Superhuman is a premium email client designed from the ground up to be, in its own words, "the fastest email experience ever made." It is not a new email service provider but a desktop and mobile application that connects to your existing Gmail or Google Workspace account. The entire product philosophy revolves around eliminating friction and latency, using a combination of a meticulously optimised interface, extensive keyboard shortcuts, and AI-assisted triage to help users process their inbox with unprecedented speed. The goal is to transform email from a daily source of stress into a tool that can be managed efficiently and cleared to zero.
The company behind Superhuman was founded in 2014 by Rahul Vohra, previously the founder of Rapportive (acquired by LinkedIn). Development was famously slow and deliberate, with a lengthy, invite-only beta period focused on obsessive refinement of performance and user experience. The company operates on a venture-backed, premium subscription model, positioning itself firmly in the high-end productivity software market. Its development continues to be heavily influenced by direct, intensive feedback from its user base, which has shaped features like the split inbox and the command-line inspired command palette.
Who is Superhuman best for?
Superhuman is a specialised tool built for a specific type of professional. It is not designed to be an email client for everyone. Its value proposition is almost entirely centred on saving time for those for whom email is a critical, high-volume part of their workflow. The substantial monthly fee is justified by the promise of reclaimed hours, making it a business expense rather than a casual purchase. In our view, it is a niche product that will feel like overkill to many but can be transformative for the right user.
- Executives, founders, and investors who receive hundreds of emails daily and need to triage, delegate, and respond with extreme efficiency.
- Sales professionals and business development reps for whom rapid email follow-up and relationship tracking are directly tied to revenue.
- High-powered assistants and operational roles who manage multiple inboxes or need to process large volumes of information quickly on behalf of others.
- Knowledge workers and consultants who treat their inbox as a central command centre and are comfortable investing time in learning a complex system to achieve long-term speed gains.
- Professionals who are already proficient with keyboard shortcuts and crave a completely keyboard-driven workflow for all their applications.
Key features
Speed and Performance Optimisation
This is the core feature. Every interaction in Superhuman is engineered for instant response. Emails open and close without perceptible lag, scrolling is buttery smooth, and searches happen in real-time. This is achieved through pre-loading emails, aggressive caching, and a codebase that prioritises performance above all else. The difference compared to standard webmail or even desktop clients like Apple Mail or Outlook is immediately noticeable and forms the foundation of the entire experience.
The Command Palette
Inspired by developer tools like VS Code, the Command Palette (activated by pressing 'G') is a universal search bar for every Superhuman action. Instead of navigating menus, you type commands like "Archive," "Schedule for tomorrow," or "Move to Project X." It learns your frequent actions and prioritises them, turning complex workflows into a few keystrokes. This centralises control and significantly reduces reliance on the mouse, which is a major speed bottleneck in traditional email.
Split Inbox and Triage Workflow
Superhuman encourages a specific methodology for clearing your inbox. The split inbox view divides your screen: your email list is on the left, and the currently selected email is on the right. This allows for rapid scanning and processing without losing context. Combined with shortcuts to archive, snooze, or delete, it facilitates a "Inbox Zero" triage process where you decide the fate of each email in seconds. Features like "Read Status" (which tracks if a recipient has opened your email) are integrated here to inform your next action.
Snooze and Scheduled Send
These are powerful deferral tools. Snooze removes an email from your inbox until a specific time or location (e.g., "when I get to the office"), when it reappears at the top. Scheduled Send allows you to compose an email and have it sent at an optimal future time. Both features help users batch their work and respect recipients' time zones, moving email from a reactive to a proactive task. They are deeply integrated and easily accessible via keyboard shortcuts or the Command Palette.
AI-Powered Triage and Composer
Superhuman incorporates AI to accelerate manual tasks. The "Summarise This" feature can condense long email threads into bullet points. More notably, the AI-assisted composer can generate full email drafts based on a brief prompt, rephrase existing text, or adjust tone. While not unique in the market, its integration is seamless and focused on shaving seconds off the composition process, aligning with the overall speed mandate. It functions as a co-pilot rather than a full autopilot.
Superhuman pricing
Superhuman operates on a single-tier subscription model priced at $30 USD per month, billed annually. There is no monthly billing option and no free tier. The only way to try the service is through a referral from an existing user, which grants a one-month free trial, or by joining a waitlist for a potential trial directly from the company. This pricing strategy is intentionally exclusive and positions Superhuman as a luxury professional tool.
In our view, assessing its value is straightforward but stark. For the average user checking personal email, $360 per year is extraordinarily poor value. However, for the target professional described earlier, the calculation changes. If the speed and workflow efficiencies of Superhuman save a high-earning individual just 30-60 minutes of productive time per month, the subscription pays for itself many times over. The value is not in feature checkboxes but in raw time savings and reduced cognitive load. When compared to other premium email clients (like Spark or Newton, which are a fraction of the price), Superhuman offers far fewer integrations and customisation options but a uniquely focused and faster core experience. You are paying for precision engineering, not breadth.
What we like
- The performance is genuinely exceptional, with a fluid, instantaneous feel that makes other clients seem sluggish.
- The keyboard-centric design, built around the Command Palette, creates a powerful and satisfyingly efficient workflow once mastered.
- The split inbox view and enforced triage methodology are highly effective for achieving and maintaining Inbox Zero.
- The onboarding process includes a mandatory, one-on-one video walkthrough with a member of their team, ensuring users understand the powerful shortcuts from day one.
- The AI features are usefully integrated into the composer and triage process, acting as practical accelerants rather than gimmicks.
What could be better
- The price is a prohibitive barrier for most individuals and is difficult to justify for anyone not using email as a primary, revenue-critical tool.
- It only supports Gmail and Google Workspace accounts, locking out users of Microsoft Outlook, iCloud, or other IMAP services entirely.
- The lack of a true calendar integration (beyond very basic viewing) is a notable omission for a premium professional tool, forcing a context switch to Google Calendar.
- Customisation options are limited; you work within Superhuman's opinionated design and workflow, with little ability to change its layout or behaviour to suit personal preferences.
Superhuman verdict
Superhuman is a masterpiece of focused software design that delivers unequivocally on its core promise of speed. It is not an email client; it is a high-performance email processing engine. Our testing suggests that for a user who receives a high volume of important email and is willing to fully commit to its keyboard-driven methodology, the productivity gains can be significant and tangible. The sensation of effortlessly clearing a packed inbox is powerful, and the quality of the engineering is apparent in every interaction.
However, this excellence comes within strict boundaries. We cannot recommend Superhuman to the vast majority of email users. If you are not a Gmail or Google Workspace user, it is immediately disqualified. If your email volume is low to moderate, or if you heavily rely on a mouse, its value evaporates. If you need deep integrations with other apps, a built-in calendar, or a flexible, customisable interface, you will find it frustratingly rigid.
Therefore, our clear recommendation is niche. Superhuman is an essential, justifiable tool for executives, investors, sales leaders, and any professional for whom email is the central, critical artery of their business and who measures time in high monetary value. For everyone else - including most knowledge workers, students, and casual users - the cost and constraints far outweigh the benefits. They should look to more affordable and flexible alternatives like Spark, Outlook, or even the steadily improving Gmail web interface itself.
