Superhuman Maik 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.

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 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.

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.

• Better UI/UX than Gmail
• Most actions can be done via keyboard (CMD+K)
• Allows for custom views, helping make email triage more streamlined
• Can easily reference Notion pages via AI to help draft your emails

• Some actions require mouse usage, breaking flow
• AI doesn’t write in your tone
• No Android app
• Not available for Outlook users

You can declutter your inbox by creating custom views using AI auto-labels or manual rules. Notion’s auto-labels have a great user interface to select the types of emails that "go together" (e.g. emails related to kids, health, etc).

However, in our testing, we found that if you decide to later update one of these customized views, you need to start from scratch as they aren't easily updated.

AI drafts tool lets you reference Notion pages or generate replies, but the writing lacks personality and runs out of credits quickly. We didn’t find the AI useful in day-to-day tasks.

If you thought Notion Mail would integrate with Notion pages or your database items, think again. That’s not available (yet anyway), leaving hardcore Notion users quite disappointed.

If you want to reference Notion pages in an email, you can tag the page and let AI generate a summary directly inside your draft.

• Incredible email and calendar foundation
• Extensive third-party integrations
• Reliable and widely supported
• Strong mobile app experience

• Visually cluttered interface (chat, meet, sidebars, colors, pop-ups)
• Slower load times compared to modern email clients
• Built for the masses, not optimized for deep work
• Labels and triage system clutter the sidebar

Since Gmail is a part of Google, it works seamlessly with their entire ecosystem. You can jump from an email into a Google Doc, attach files from Drive instantly, launch a Meet call, or collaborate in Sheets without leaving the platform.

For teams already using Google Workspace, this integration is extremely powerful.

Gmail now has Gemini fully embedded into helping you write emails. You can now use their "Help Me Write" feature, and it will analyze previous emails to draft a reply in your tone.

Gmail also uses Gemini to help you search your inbox. Instead of typing keywords and hoping you remember the exact phrase from an email, you can ask it a normal question like, "When did I last speak to Sarah about the proposal?" or "Did the client ever approve the contract?" It will scan your inbox, give you a direct answer, and show you the emails it pulled that information from. That part is genuinely helpful, especially if you handle a lot of conversations and forget details.

The Gmail mobile app has a significantly better experience than even the web app in many ways. It's easy to navigate, loads relatively quickly, and is an overall good experience. They let you set swipe actions (Archive/Snooze/Delete) and get quite granular on the notification settings as well.

Although you'll run into some limitations using the Gmail app that will slow down your workflow. For instance, you cannot create hyperlink when composing an email within the app.

• Built-in email screening
• Fresh @hey.com address with little to no spam history
• Opinionated, simplified inbox structure
• Custom domain support available

Hey is primarily geared toward personal users who are looking to leave Google or Microsoft behind and trying an entirely new email client.

However, that does come at a cost... If you're fully moving away from the broader Google or Microsoft ecosystems, this means giving up the integrations, APIs, and flexibility that most businesses rely on.

So, while Hey is generally not well-suited for business users who depend on tools like CRMs, automation platforms (e.g., Zapier), or advanced calendar integrations.

This is Hey's most differentiated feature. They have a built-in gatekeeper situation, so before a new sender can land in your inbox, you must approve them. If you don't approve them, they never get through.

Credit where credit is due, this feature dramatically cuts back on spam and gives you more control over who gets your attention.

Hey doesn’t use a traditional inbox. Instead, it separates emails into different buckets like "Imbox" (for conversations) and "The Feed" (for newsletters).

The intention is to make inbox zero feel achievable and reduce the constant overwhelm of a single endless stream of emails.

It is a very opinionated structure that you don’t customize or control, but instead, adopt. For some people, that simplicity is refreshing. For others, especially power users who are used to labels, filters, and custom workflows, it will feel limiting.
