Email Is Not Broken. Email Clients Are.

Isaac Hinman

Every few months, someone raises a round of funding to "fix email." They launch with AI-powered inbox sorting, smart categorization, natural language commands, and a pitch deck that says email is fundamentally broken and only machine learning can save us.

They're wrong. Email is not broken... email is one of the most successful communication protocols ever created. It's open, decentralized, and interoperable. You can send an email from any provider to any other provider on earth, and it just works. No vendor lock-in. No platform approval. No algorithm deciding who sees your message.

What's broken is what we've built on top of it.

Email clients are the problem

The modern email client has become a product in search of a problem. Instead of making email fast, reliable, and private, the industry has spent the last decade adding features that serve the client's business model, not the user's needs.

Gmail scans your emails to sell ads. That's not an email problem. That's a business model problem.

Superhuman charges $30/month for keyboard shortcuts and read receipts. That's not solving email. That's selling productivity theater.

Spark routes your messages through their servers to power "smart" features most people never asked for. That's not improving email. That's creating a privacy liability.

And now every email client is racing to add AI. Summarize this thread. Draft this reply. Categorize my inbox. As if the solution to having too much email is to have a machine read it for you instead of questioning why you're subscribed to 40 newsletters you never open.

The AI inbox is a solved problem looking for validation

Let's talk about AI in email specifically, because it's become the default feature that every new email client ships with.

AI email summaries save you the time of reading an email by giving you a worse version of what the email says. AI draft replies save you the time of writing a response by generating something you'll spend just as long editing. AI categorization saves you the time of organizing your inbox by organizing it in ways you wouldn't have chosen yourself.

These features look impressive in demos. They generate great screenshots for Product Hunt launches. But they solve surface-level symptoms while ignoring root causes.

If you're getting too many emails, the answer isn't an AI that summarizes them. The answer is unsubscribing, filtering, and being deliberate about what reaches your inbox.

If you're spending too long writing replies, the answer isn't an AI that writes generic responses. The answer is writing shorter emails, or picking up the phone / getting on a call.

If your inbox feels overwhelming, the answer isn't algorithmic sorting. The answer is a fast client that lets you process email quickly and get on with your day.

What email actually needs

Email needs three things from a client, and the industry has somehow managed to complicate all of them.

Speed: Email should be instant. Opening a message should take zero perceivable time. Search should return results before you finish typing. Switching between accounts should be seamless. This is a solved problem technically. Local storage and good indexing make email fast. But most clients don't invest in this because it's not a feature you can put on a landing page.

Privacy: Your emails are the most comprehensive record of your life that exists. They contain your financial information, your medical records, your legal documents, your personal conversations. An email client should treat this data with extreme care. It should not scan your messages for ad targeting. It should not use your data to train AI models. It should use IMAP, the open standard, not proprietary APIs that lock you into a specific provider. That's the architecture that respects your privacy.

Reliability: Email should work everywhere, all the time: on a plane, on a train, in a basement with no signal. Offline access isn't a premium feature, it's a baseline requirement for any serious email client. Your emails should be on your device, and you should be able to read, search, compose, and organize without an internet connection. When you reconnect, changes should sync automatically.

Speed. Privacy. Reliability. That's the entire product spec for a great email client. Everything else is noise.

The case against "reinventing" email

There's a persistent fantasy in tech that email can be "reinvented." That if we just add the right AI model, the right notification algorithm, the right social features, we'll transform email into something better.

But email doesn't need reinvention. Email is a protocol for sending messages between people. It's been doing this reliably for decades. The protocol works. The standard works. The interoperability works.

What needs to change is the layer we interact with. The client. And the change needed isn't addition. It's subtraction.

Remove the ad scanning. Remove the server-side processing. Remove the AI categorization. Remove the smart inboxes and priority sorting and social integrations. Strip email back to what it is: messages from people, delivered to your device, searchable and accessible at any time.

Marco's philosophy

Marco exists because we believe the best email client is one that disappears. You open it. You read your email. You reply. You close it. You get on with your life.

No AI summaries. No smart categorization. No server-side processing of your messages. No features designed to keep you inside the app longer.

Marco connects to your email provider via IMAP, the open standard. Your emails sync to your device. Search is local and instant. Everything works offline. We never scan, analyze, or monetize your data.

This is boring technology. IMAP is 40 years old. Local storage is not novel. Full-text search indexing is a solved problem. There is nothing cutting-edge about what Marco does.

And that's the point. Email doesn't need cutting-edge. Email needs fundamentals, executed well. Fast, private, reliable. That's it.

Build for humans, not for demos

The email client industry optimizes for demos, fundraising decks, and Product Hunt launches. "Look, AI wrote your reply!" "Look, smart sorting organized your inbox!" These are features that impress investors and generate buzz. They are not features that make your Tuesday morning better.

Marco optimizes for your Tuesday morning. For the moment you open your inbox, find what you need in seconds, respond to what matters, and close the app. No wizard behind the curtain reading your emails. No algorithm deciding what's important. Just your messages, on your device, ready when you are.

Email is not broken. Your email client is. And the fix isn't more features. It's fewer features, done right.
