• Wildly fast performance (literally instant compared to Gmail/Outlook)
• Minimal, beautifully designed interface with zero clutter
• Team email collaboration features helps move emails forward more quickly and seamlessly
• Deep-work friendly (no distractions, no unnecessary features)
• Mobile app on iOS and Android to help you triage emails on-the-go

• Might feel unnecessary if you don't spend much time in email
• While you can share emails and drafts with your team, you cannot assign emails and have your team answer on your behalf

The first time we opened Superhuman Mail, it genuinely felt like a different category of email tool. The wall of emails we were used to see just wasn't there instead it had been replace with a clean, fast interface that made it feel like this is the only email client actually designed for deep work.

The use of inbox splits makes brings allows for purpose and intention when managing your emails. There’s nothing visually overwhelming or distracting, which, if you spend hours in your inbox like we do, makes a massive difference. It doesn’t feel like you’re “doing email.” It feels like you’re focused.

Pair that with a mobile app that is purposefully designed to allow for triaging emails with speed and clarity and it honestly makes it impossible to go back.

Superhuman Mail actually drafts email responses in your tone. It learns from your previous messages and responds as you would.

Secondly, Superhuman Mail figures out if an email you sent needs a follow-up/nudge, and it automatically drafts a follow-up in your voice and leaves it in your inbox for you to hit send (yes, just like an executive assistant would). This makes it fantastic if you're doing sales out of your inbox.

Third, Superhuman Mail uses AI to search your inbox. Forget trying to find the perfect search term to surface an email. With Superhuman Mail, you can ask any question in plain language, and it will give you an AI summary response (e.g., "Where was the conversation left off with XYZ? When is the last time I spoke to XYZ?"). And you can even use the AI Chat for other things, like telling it to create a calendar invite.

Similar to read receipts in text messages, Superhuman Mail shows you exactly who opened your email, how many times they viewed it, and when they opened it. It's super helpful if you're waiting on a reply.

Superhuman Mail is also one of the best calendar apps and best scheduling apps if you live within your email. Why?

Say you get an event email with no calendar invite, just hit [b] and Superhuman Mail will instantly create an event for you (I absolutely love this feature). Or if you're writing to someone, and you say "let's meet next Tuesday" your calendar automatically pops open on the right so you can quickly check your availability.

Want to share your availability quickly? No worries, hit the keyboard shortcut and [CMD] + [SHIFT] + [a] and send over your free time slots in seconds so they can book in.

Superhuman Mail also allows you to triage through your inbox using only keyboard shortcuts.

I was a skeptic for years, until I finally gave it a shot. Learned some of the simple keyboard shortcuts like [e] for archive and [h] for snooze + some additional fun shortcuts like [#] for delete, and [!] for spam.

Just hit [0] to instantly open your calendar on the right-hand side without leaving your inbox, giving you a full view of your schedule while you continue working through emails.

Don't like memorizing keyboard shortcuts to get through your email more quickly? Great, then just press [CMD] + [k] for the command bar → the Superhuman Mail key, which allows you to do absolutely anything from anywhere just by typing.

You can share email threads with others (whether they are on your team or not) so you can collaborate under email.

This has come super handy for us when we've had sales negotiations (very helpful to @mention each other and check-in if what is proposed makes sense), or to more thoughtfully respond to a customer. Read our entire Superhuman Mail Team Comments review here.

• Works directly inside Gmail and Outlook
• AI auto-labeling for quick inbox categorization
• Basic meeting scheduling and AI note-taking included
• Lower intimidation factor for teams resistant to switching tools

• Not a true email client (limited by Gmail/Outlook’s structure)
• Label-based system doesn’t properly support inbox zero
• AI drafts feel generic and often require editing
• Limited customization of labeling and draft logic
• Pricing is high for what is essentially an AI wrapper

Don't mistake this for a true split inbox, because in reality, this feature relies on Gmail-style labels. So while it does automatically categorize emails into buckets like “To Respond,” “FYI,” and “Notifications,” It also makes your emails feel cluttered and repetitive quickly. Overall, helpful in theory, but not really in practice.

Similar to other email clients, Fyxer gives you the ability to generate draft replies to incoming emails. While it does seem convenient, we noticed the responses often lack deep context and personalization compared to its competitors.

More than that, Gmail now natively uses Gemini to help write in your tone, and pull information from Google Drive and previous emails so part of the value has dropped here.
