Notion Kills Skiff-Influenced Email App as Most Users Switch to AI Agents
Notion announced the shutdown of its email client Notion Mail, built on technology from the acquired startup Skiff, citing that most users now prefer AI agents for email management.
Notion has announced it is shutting down its email client Notion Mail, which was developed using the infrastructure and expertise of the acquired startup Skiff. Skiff had served 2 million users and was a strong competitor to services like Proton Mail before its acquisition. Notion Mail, a Gmail client without end-to-end encryption, focused on AI-driven features rather than the privacy that defined Skiff's original offering.
The company urges users to export their drafts and scheduled emails by September 21, as these will not automatically transfer to another app. However, users can save their Notion Mail configurations, including snippets and auto-label instructions. According to a post on X, users with auto-label rules can recreate them using a Custom Agent, and existing Notion agents managing email will continue to function. The email connection within Notion remains intact.
Organizations relying on Notion Mail in regulated environments, such as those requiring HIPAA compliance, must transition by June 30, 2026. Although Notion is discontinuing the Skiff-influenced email app, it may continue leveraging the human resources and productivity concepts—such as calendar and storage features—gained from the Skiff acquisition to compete with rivals like Google Workspace. However, Notion has not released direct successors to Skiff's original product lineup.
