Notion, a productivity platform, has announced that it will be shutting down its email client, Notion Mail, on September 22. The decision comes as users increasingly rely on AI agents to manage their inboxes, making traditional email clients redundant. This shift marks a significant trend in the industry, with companies like Notion and others investing heavily in AI-powered tools.

What Happened

Notion Mail was launched in April 2025 as part of the company's broader push to become an all-in-one workspace, competing directly with Google Workspace and Microsoft 365. However, despite its relatively short lifespan, Notion Mail has already seen a significant shift in user behavior. According to Notion, more than half of its users manage their emails without ever opening their inbox, instead relying on AI agents to handle email workflows.

This trend is not unique to Notion Mail. The company's developer platform supports agents that can read, write, and act across Notion workspaces, handling the kind of cross-application coordination that email was originally designed to facilitate. This shift towards AI-powered tools has been accelerated by the rapid growth of agent capabilities in recent months, with companies like OpenAI and Google pushing the boundaries of what is possible.

Background and Context

The decision to shut down Notion Mail is not a surprise given the company's pivot towards AI agents as its core product direction. In May, Notion launched a developer platform that lets third parties build AI agents on top of Notion's workspace, with over one million agents already built on the platform. This move reflects a broader trend in the industry, where companies are investing heavily in AI-powered tools to automate tasks and streamline workflows.

Notion's acquisition of Skiff, an encrypted email and productivity software startup, in February 2024 also played a significant role in the development of Notion Mail. The team and technology from Skiff were brought into Notion, where they were used to build Notion Mail. However, despite its potential, Notion Mail ultimately failed to gain traction with users, who increasingly preferred to rely on AI agents to manage their email.

Why It Matters

The shutdown of Notion Mail marks a significant shift in the industry towards AI-powered tools and away from traditional email clients. This trend has implications for companies that provide email services, as well as those that offer productivity software. As users increasingly rely on AI agents to manage their inboxes, companies will need to adapt and invest in AI-powered tools to remain competitive.

The shift towards AI-powered tools also raises questions about the future of work and the role of humans in managing email. While AI agents can handle many tasks efficiently, they often lack the nuance and context that human judgment provides. As users increasingly rely on AI agents to manage their email, companies will need to balance the benefits of automation with the potential risks of losing human touch.

What Comes Next

The shutdown of Notion Mail marks a significant turning point for the company, which is now doubling down on its AI agent offering. The company's developer platform supports agents that can read, write, and act across Notion workspaces, handling the kind of cross-application coordination that email was originally designed to facilitate.
