Notion has announced it is shutting down Notion Mail, its email app, and the company’s reasoning is pretty straightforward: most users have already moved on to AI agents to manage their inboxes.
The decision is a bit surprising, but it makes sense once you understand the context.
Notion Mail was born out of a strategic acquisition — Skiff, a platform that had amassed 2 million users before being purchased by Notion.
With all that technological heritage, the email app launched in April 2025 with a heavy focus on artificial intelligence, but it didn’t last long.
Now, the company is laying out the timelines for data export, exceptions for regulated environments, and what happens for those who were already using AI agents to manage their messages.

From Skiff to Notion Mail: a short but intense story
When Notion acquired Skiff, a lot of people were curious about what was coming next. Skiff was a productivity platform with a strong privacy focus, offering a document editor, cloud storage, and of course, an email client with end-to-end encryption. With 2 million active users, the base was solid enough to give competitors like Proton Mail a run for their money. Notion saw a clear opportunity to expand its ecosystem, leveraging both the technical infrastructure and the talent behind the platform.
One important detail is that Notion Mail wasn’t built from scratch. It was developed on top of Skiff’s own infrastructure and by former executives from the company who joined Notion after the acquisition. In other words, there was a lot of Skiff DNA inside that product, which makes its shutdown something of a swan song for everything Skiff represented. It’s almost like watching the final chapter of a story that began with a lot of ambition in the world of digital privacy.
In April 2025, Notion Mail officially launched. Featuring a clean interface and direct integration with the Notion workspace, the app arrived with a clear differentiator: the heavy use of AI (artificial intelligence) to organize, prioritize, and even respond to emails automatically. It’s worth noting, however, that Notion Mail essentially functioned as a client for Gmail and did not offer end-to-end encryption. That means it abandoned the very privacy focus that was Skiff’s calling card, swapping it out for an approach centered on productivity and automation. On paper, it was exactly the kind of tool Notion users would love. In practice, the market was already heading somewhere else.
Why Notion decided to shut down the email app now
Notion’s official explanation is straight to the point: most users had already migrated to AI agents to handle their inboxes. Instead of opening a dedicated email app, these people started delegating the sorting, reading, and even replying to messages to artificial intelligence tools that work more seamlessly within already-automated workflows. Notion Mail, as well-built as it was, found itself competing with a trend it had helped create in the first place.
This scenario raises an interesting question about the product’s timing. Notion Mail launched at a moment when AI agents were already gaining momentum fast in the productivity space. Tools showing that the future of email wasn’t necessarily a separate app, but rather an intelligent layer on top of what already existed, were becoming increasingly popular. Keeping Notion Mail alive would have required ongoing investment in development, support, and infrastructure for a product that, according to the company’s own internal data, was losing relevance in users’ daily routines.
From a strategic standpoint, it makes a lot of sense for Notion to focus its resources on areas where AI can add more value within its core product. The company already has a massive user base that relies on the platform for project management, documents, wikis, and knowledge bases. Expanding AI agents within those areas, rather than maintaining a separate email app competing against giants like Google Workspace, seems like a much more coherent bet for the company’s long-term positioning.
What happens to the data and who gets an exception
For those who were using Notion Mail, the company is already communicating the timelines and processes for data export. Notion has directed users to export drafts and scheduled emails by September 21, since those items won’t be automatically transferred to an alternative app. The good news is that you can save your Notion Mail settings, including exporting snippets and auto-labeling instructions to use elsewhere. That level of care makes a real difference, especially given the history of transitions that haven’t always gone smoothly.
For those who were using the auto-label feature inside Notion Mail, the company also brought a practical solution to the table. You won’t need to rebuild everything from scratch — just create a Custom Agent in a few clicks, and Notion takes care of bringing over your existing rules automatically. And there’s more — anyone already running Notion agents to manage email doesn’t need to worry, because those agents will keep working as usual. The email connection within Notion stays active, ensuring continuity for anyone who had already adopted that workflow.
There is, however, one important exception: regulated environments. Organizations that relied on Notion Mail in contexts with compliance requirements may need to make the transition sooner. In the specific case of those who depend on HIPAA coverage (the U.S. law protecting health data), Notion recommends planning your exit from Notion Mail by June 30, 2026. Sectors like healthcare, finance, and legal often have specific requirements around email communication storage and management, which is why they’re getting special treatment during this transition.
What this reveals about the future of Notion and AI
The shutdown of Notion Mail isn’t a sign of weakness. It’s actually a pretty honest reading of where the productivity market is headed. Companies building work tools are realizing that the model of separate apps for each function — email over here, documents over there, tasks somewhere else — is giving way to integrated environments where AI connects everything. Notion is betting that its differentiator isn’t having its own email client, but rather being the central hub where work happens, with intelligent agents operating in the background.
Even while discontinuing the Skiff-influenced email client, Notion will likely continue leveraging a lot of what it gained from that acquisition. We’re talking about the talent that came on board and productivity ideas related to calendars and storage, for example. All of that helps Notion compete more robustly against rivals like Google Workspace. Interestingly, though, the company has avoided launching products that are direct continuations of the portfolio Skiff once offered, preferring to absorb the learnings rather than replicate the same products.
This shift in mindset is important for understanding the company’s next moves. In recent months, Notion has been investing heavily in expanding its AI capabilities, including content generation features, automations, and more recently, agents that can execute complex tasks within the workspace. Shutting down the email app frees up human and financial resources that can be redirected toward these initiatives, accelerating the development of features that have a much bigger impact on users’ daily lives.
For the market as a whole, the Notion Mail story is a clear example of how artificial intelligence is reshaping the priorities of tech companies. Products that made perfect sense two or three years ago can quickly become redundant when AI agents start taking over the tasks those products were built to solve. Email has always been a productivity problem — full of interruptions, hard to organize, and a huge time sink. AI didn’t solve it by building a better app; it simply started managing the problem on its own, and Notion was honest enough to recognize that. 🤖
