The Rationalists, a community focused on the risks of artificial intelligence, regularly gather with tech figures and other like-minded people in a complex that covers much of a city block.
When you’re the glue connecting executive vision with day-to-day operations, you can’t afford to let your inbox be a bottleneck.
The Superhuman team recently joined Phil Burns, founder and executive director of The Chief of Staff Roundtable, for an episode of “Tools of the Trade” — deep-dives into tools that Chiefs of Staff rely on to be more effective, productive, and decisive.

Phil spoke with Paul Teyssier, President at Superhuman, and Rosellen Schwartz and Amanda Marx from our Customer Success team. They covered:
Common problems with email and how they especially impact Chiefs of Staff
How Superhuman turns your inbox into a catalyst for speed, focus, and alignment
Inbox woes: overwhelm, slow response times, and hidden busy work
Too often, inboxes become bottlenecks. Professionals are overwhelmed with a flood of messages, competing priorities, and cascading back-and-forths, making it difficult to focus on what truly matters.
“Email is one of the biggest productivity problems hiding in plain sight,” noted Paul. The way most professionals use email hasn’t really changed in decades. And that means there’s unnecessary friction and overwhelm in one of the core modes of work.
For Chiefs of Staff, the impact of these challenges is even greater. Email isn’t just a communication tool — it’s a command deck for decision-making, alignment, and execution. Any drag in the inbox is drag on the critical business decisions Chiefs of Staff and leaders make constantly: Which requests get a response first? What needs escalation? What can wait?
This drag takes a toll in missed opportunities, ignored risks, and unsatisfied partners and customers.
“It can become an absolute hurricane of chaos, trying to keep everything straight,” says Phil, noting the special challenge for Chiefs of Staff in managing leaders’ inboxes as well as their own.
Paul highlighted three email problems that particularly affect Chiefs of Staff:
Volume overload: The sheer number of incoming messages can create decision fatigue and make it hard to keep track of what’s important and urgent. This is especially true when managing leaders’ inboxes and coordinating with EAs as well.
Slow response times: Being responsive to what matters most is crucial for succeeding in this role. You need to feel confident that you can reliably surface the key opportunities and risks from incoming emails, and drive momentum with followups without dropping the ball.
Hidden work: With email volume comes the tedious inbox overhead of sorting, filing, tracking tasks, and piecing together threads. It can quickly feel like an extra job to keep your inbox organized and under control.
“These challenges tend to be 10 times bigger for Chiefs of Staff than in most other roles. Your ability to stay on top of things and unblock things, before other people even know they’re blocked, is a really critical element.”
— Paul Teyssier, President at Superhuman
Superhuman: a catalyst for focus, speed, and alignment
Paul noted that Chief of Staff is one of the most common job titles among Superhuman customers. Many have recognized the opportunity to become far more productive in their inbox, often driving change for others in their organizations.

Superhuman transforms your inbox from a bottleneck into a catalyst for speed, focus, and alignment — helping Chiefs of Staff and senior leaders work seamlessly together, prioritize the right messages, and clear email faster.
Phil gets it. After using Superhuman for 5 weeks, he’s at 1,500 unread emails, down from 4,000 — steadily improving his productivity with the Inbox Zero method.
“Superhuman is in a league of its own. It has absolutely revolutionized my inbox with little to no effort.”
— Phil Burns, Founder and Executive Director of The Chief of Staff Roundtable
Here are three powerful ways Chiefs of Staff use Superhuman.
Focus on what matters
Better inbox triage and priority management means better, faster decision-making.
With Split Inbox, you can organize emails into distinct workstreams or areas of focus. This transforms the overwhelming single inbox experience into categorized sections — dramatically reducing context switching and decision fatigue, enabling users to stay in flow while focusing on what matters most.
With Reminders and Split Inbox, your inbox becomes your to-do list. Amanda demonstrated how to rapidly triage email with the decision framework: Is it for today, for another day, or done? This makes each inbox split a prioritized and actionable overview of work, with everything else out of sight and off your mind.
Auto Summarize shows a 1-line summary above every conversation. You can simply tap a key to see an expanded summary. This gives you vital information at a glance, so you can fly through your inbox.
Respond faster, effortlessly
Superhuman helps you respond faster to what matters most.
Recent Opens is a live feed of who is opening your emails. You can effortlessly keep the pulse of high-stakes conversations — and follow up with perfect timing.
Superhuman AI can draft entire emails based on simple prompts, refine existing drafts, and fix grammar and formatting. It’s a fast, skillful writing assistant that adopts your own voice and tone, and even learns to adapt how it sounds based on each recipient.
Snippets are templates for common responses, easily shared across your team so your best messaging stays consistent and on brand. You can even see analytics on Snippet usage, helping teams track which messaging is most effective.
Instant Reply offers rapid, pre-drafted responses. Perfect for those emails that just need a quick acknowledgment to keep things moving.
The latest evolution of Superhuman AI means you’ll never miss a followup again. With Auto Reminders & Auto Drafts, you’ll get a timely reminder to respond and even a pre-drafted reply — ready to simply skim and send.
These features directly address what Paul identified as a key pain point for Chiefs of Staff: “Slow response time to customers, slow response time to peers, slow response time to the different leaders you’re supporting… which can eventually put your business at a disadvantage.”
Collaborate more effectively
With Superhuman, you can collaborate right from your inbox — without the need to forward, bcc, or jump between apps. You can align faster with your team and delegate seamlessly.
Shared Conversations & Team Comments allow for internal collaboration on external conversations without creating separate email threads. All the context stays in one place while keeping a clear distinction between internal and external discussion, preventing accidental sharing.

Shared Conversations eliminate a common source of friction for Chiefs of Staff — trying to get rapid alignment with busy leaders on something that has both internal and external context. Instead of a snowball of open tabs and loops — e.g. when there’s an email from a customer that’s then forwarded internally to the CEO, that the EA then replies to and the Chief of Staff then manages, creating an extra thread that is disconnected but can collide with the main conversation with the customer, and even more open loops to close… ugh! — with Superhuman, there’s one single, always up-to-date view.
Share Availability makes scheduling effortless. No more endless back-and-forth to book a meeting — simply pick your ideal times and share, with far more control than add-ons like Calendly.
Extra speed, focus, and alignment in your inbox pay off. One of the largest strategy consulting firms now responds to emails 3.6 hours faster on average and sends 60 percent more emails after implementing Superhuman.
“Anecdotally, they’ve told us that with Superhuman, they’re never dropping the ball, and they have more time and more energy to spend resolving customers’ issues and engaging with new customers,” Paul shared.
Chiefs of Staff rely on Superhuman to make faster decisions, keep leadership informed with minimal friction, and focus on what matters most.

I am beyond thrilled to announce our next chapter: Superhuman is being acquired by Grammarly. Together, we will build the AI-native productivity suite of choice!
We will now accelerate our entire roadmap. We will invest even more deeply in AI and email, build new experiences that transform how we collaborate and communicate, and create AI agents that unlock a whole new way of working. More below…
Superhuman & Grammarly 💜
I met Shishir Mehrotra — co-founder of Coda, and now the CEO of Grammarly — back in 2017.
I had just onboarded him onto Superhuman. As he closed Gmail, another tab caught my eye: an app called Krypton. I asked what it was. Shishir then gave me the best product demo I had seen in years!
Krypton became Coda, and Coda became the collaborative document of choice for tens of thousands of teams and millions of users. In late 2024, Grammarly acquired Coda, and Shishir became the new CEO.
In their acquisition announcement, Shishir wrote: “As I watched the foundational capabilities of AI change how just about every tool and surface operates, I started drafting my 2025 planning memo for the team. I titled it: the AI-native productivity suite.”
At Superhuman, our vision has always been to build the AI-native productivity suite of choice. Email is a critical part of this suite, and a much bigger problem than most people realize: there are roughly 1 billion professionals in the world, and on average we spend 3 hours a day in email. That’s 3 billion hours every single day, or more than 1 trillion hours every year. In fact, we spend more time in email than any other work app.
When I read Shishir’s post, I knew we should catch up.
The AI superhighway ✨
For professionals, email turns out to be the number one Grammarly use case: the assistant helps write over 50 million emails every week. Grammarly itself is extraordinarily popular: it is used by over 40 million people and 50,000 organizations. We used the phrase “hand in glove” more than a few times!
Grammarly also has incredible potential. At first glance, it is an AI writing assistant. But unlike every other AI assistant, Grammarly works in every app. To pull this off, the team has built integrations with 500,000+ apps and websites — an impressive feat of engineering they call the “AI superhighway.” So far, that AI superhighway has delivered an AI writing assistant. Grammarly is now working on hundreds of task-specific agents, and will use this superhighway to bring these agents to users wherever they work, including — of course — email.
The agentic future of work 🧠
With greater resources, we will now accelerate everything we do. We will invest even more in AI and our core email experience. We will build calendar and tasks, connecting them beautifully together. We will reimagine chat and redefine collaboration. And we will create a new way of working with AI agents.
Email turns out to be the perfect place to work with agents. Imagine an agent triaging your inbox before you wake up; another agent drafting responses in your own voice and tone, incorporating detailed context about you and your work; while another agent surfaces insights, schedules meetings, and interacts with other agents and your systems of record.
We could not be more excited to build the future of work — an AI-native productivity suite, with agentic workflows that are deeply integrated into every part of your day!

Imagine how productive you could be with constant help to organize, prioritize, and take care of your email.
In a recent virtual event, we showcased the next evolution of Superhuman AI. Matt Waters, Senior Manager of Customer Enablement, and Lorilyn McCue, Principal Product Manager demoed the groundbreaking AI-native features that help teams get twice as much done in their inbox.
The majority of knowledge professionals suffer from email overload. High email volume plus poor organization takes a big toll on productivity and blurs priorities.
With Auto Labels, Superhuman automatically classifies incoming messages — so you can focus on what matters most.
We talked to hundreds of executive assistants and executives to better understand how they do their best work. Auto Labels are inspired by how the most productive EAs use inbox labels to help their executives get more done.
Every Superhuman customer can use our built-in Auto Labels: Marketing, Pitch, Social, and News — common lower priority emails that often create inbox noise.
Custom Auto Labels
Custom Auto Labels let you categorize emails with your own AI prompts. (Available for our Business and Enterprise customers.)
Custom Auto Labels offer unmatched flexibility to organize and simplify your inbox. Use natural language prompts like:
“Messages applying for or asking about open job positions”
“Messages related to Project Acme”
“Any email with an invoice, receipt, or bill”
“Review requests from my team”
Auto Labels use Superhuman AI to categorize conversations based on their content, subject, sender, and recipients.
Matt demonstrated how to get the best results from your prompts, and how Auto Labels can power other features like Split Inbox and Auto Archive.
Split Inbox
Auto Labels work with Superhuman’s Split Inbox — constantly helping to categorize emails you can batch process them at the optimal time.
Matt finds the most helpful custom splits are for:
Low-urgency information that you might read and respond to more slowly than email in your primary splits — like automated updates and newsletters.
High-priority emails that benefit from being processed in a batch, maintaining focus — like review requests and project-based emails.
Auto Archive
We all receive emails we don’t want to process immediately — and others we don’t want to process at all.
With Auto Archive, emails skip your inbox altogether. (You can still find them later if you want to, via search or the Auto Archived folder.)
Auto Archive keeps your inbox clutter-free and reduces distractions.
Auto Archive will not skip messages from people that you’ve emailed before or from people on your domain, so you’ll never miss an important message.
Auto Reminders & Auto Drafts
The most effective emailers are excellent at following up on their own sent messages.
Following up demands consistent effort and discipline — yet follow-ups still slip through the cracks. Every slip costs you stalled work or a missed opportunity.
Auto Reminders automatically resurface emails that haven’t received a reply, so you’ll never miss a follow-up again.
With Auto Drafts, your reminder even comes with a follow-up draft written by AI in your voice — so you just have to review and send. (Available to Business and Enterprise customers.)
The Next Next Evolution of Superhuman AI
Lorilyn mentioned the exciting work the Superhuman AI product team is developing, including the expansion of Auto Draft capabilities, Auto Label Libraries to help teams collaborate more effectively, and calendar power-ups.
