Notion Is Shutting Down Its Email App Because AI Took Over

Notion is shutting down Notion Mail, its email app that used technology from the Skiff acquisition. About half of its users never opened it. Those who did mostly let AI agents handle their inboxes instead of using the app themselves.

What Happened

Notion Mail started as a standalone email client after Notion acquired Skiff, a privacy-focused document and collaboration startup, in early 2024. The goal was to integrate email management into the Notion ecosystem, allowing users to manage notes, projects, and their inbox all in one place.

However, the experiment is coming to an end. In a company announcement, Notion stated it is “going all in on using agents to run your inbox.” This means AI programs will read, sort, and respond to emails for you, rather than keeping a traditional email app that you interact with directly.

The statistics reveal the challenge: around 50% of Notion Mail users never engaged with the app meaningfully. That’s a tough number for any product to overcome.

The Skiff Connection

Skiff was recognized for its end-to-end encryption, which ensures only you can access your own data, not even the company that stores it. When Notion acquired Skiff, many privacy-conscious users felt disappointed, and Skiff’s standalone products were discontinued. Notion Mail was meant to be the successor to Skiff Mail — and now it’s disappearing too.

For former Skiff users who transitioned to Notion Mail in hopes of a similar experience, this marks a second disruption in about two years.

Why AI Agents Are Replacing the App

Think of an AI agent as a highly capable assistant that monitors your inbox around the clock. Instead of you logging into an email app, reading messages, deciding what to act on, and writing replies, the agent takes care of those tasks and only highlights what truly needs your attention.

Notion believes this model is more beneficial than a traditional email client. Since users primarily engaged with Notion Mail through its AI features rather than the app itself, it shows where the real value lies. Maintaining a full email app just to support AI automation is an expensive approach.

This reflects a broader trend in productivity software: companies are reducing the focus on interfaces and increasing reliance on automation. The app itself becomes less critical when an agent can manage things for you.

Community Reactions

“Notion bought Skiff, killed Skiff, built Skiff Mail into Notion Mail, now killing Notion Mail. If you were a Skiff user, you’ve been moved twice and now have nothing to show for it.”

“Honestly not surprised. I signed up for Notion Mail and used it for like two weeks. The AI inbox summary was the only part I actually cared about. Just give me that in the main Notion app.”

What This Means

If you currently rely on Notion Mail as your main email client, you’ll need to switch to another app. Gmail, Outlook, and Apple Mail are the obvious alternatives. Tools like Mimestream or Superhuman offer a cleaner, more focused email experience.

For everyday Notion users who never interacted with Notion Mail, there won’t be any changes — your notes, databases, and project pages will stay the same.

The bigger picture shows where Notion is headed. Instead of creating more apps and surfaces to manage, the company is focusing on AI that operates in the background and takes care of routine tasks automatically. Whether this is more convenient or just less transparent depends on how much you trust software to make decisions for you.

This also raises questions for anyone considering Notion as an all-in-one workspace. The promise has always been about consolidation — one tool for everything. However, shutting down a major feature like email indicates that the “everything” aspect has limits, and those limits change based on user adoption.

What To Watch

• Migration deadline: Notion hasn’t announced a specific shutdown date for Notion Mail yet. Users should keep an eye out for official communication regarding data export options and how long the service will stay active.
• AI agent rollout: Notion has indicated a broader shift towards agent-based features within its core product. Look for announcements about inbox automation in the main Notion app in the coming months.
• Skiff community response: Former Skiff users have already experienced one forced migration. How Notion manages this second disruption will impact trust among privacy-focused users who are already wary.
• Competitor response: AI startups focused on email, such as Shortwave and Superhuman, could become appealing options for displaced Notion Mail users and may try to attract them with targeted offers.
