Notion has announced the shutdown of Notion Mail, its email app launched in April 2025, effective September 22, 2026. The decision, shared via an X post, ends the project born from the acquisition of Skiff, an encrypted email and productivity startup purchased by Notion in February 2024. The primary reason, according to the company, is that most users no longer rely on traditional email clients, instead delegating correspondence to AI agents.
From Skiff acquisition to Notion Mail launch
In February 2024, Notion acquired Skiff, which offered encrypted email and productivity tools. Within a year, Notion shut down Skiff's email service, removing @skiff.com addresses. In April 2025, the San Francisco-based company launched Notion Mail, a Gmail client built largely by the former Skiff team. The app aimed to integrate email into the Notion ecosystem with features like snoozing and auto-categorization.

The rise of AI agents as an alternative to email clients
Notion's post stated that the shutdown stems from changing user behavior: more people rely on AI agents to filter, reply, and organize messages autonomously. This trend, already visible across the industry, has led Notion to focus on AI-powered solutions. The company declared it is "going all in on using agents to run your inbox," echoing the growing trust in AI for complex tasks, as seen in SpaceX's acquisition of Cursor, which highlights the challenge of trust in AI code generation.
Timeline and user impact
The shutdown is set for September 22, 2026, after which the app will no longer be accessible on web, desktop, and iOS. Current users will have a transition period to export data. The announcement has drawn mixed reactions: some users must find alternatives, while others see it as a step toward deeper AI integration in productivity. The heatwaves straining European power grids remind us of the importance of reliable digital services, which Notion aims to ensure with its agent-based systems.
