Notion killing Skiff-influenced email app since most users use AI agents instead

Notion announced plans to discontinue its Notion Mail service, marking another chapter in the ongoing transition following the company’s acquisition of encrypted email startup Skiff in February 2024. The San Francisco-based productivity platform stated that the email client’s inbox will be removed across web, desktop, and iOS platforms on September 22.

The decision reflects a strategic pivot toward artificial intelligence-driven email management. In a statement posted to X, Notion indicated that as its agent technology has advanced, user behavior has shifted accordingly. The company reported that more than half of Notion Mail users now manage their emails through automated agents without opening their inbox directly. Notion characterized this trend as validation of its belief that email systems should operate with increasing levels of artificial intelligence capability.

Users will retain access to their email history through Gmail, where messages will remain stored following the shutdown. However, Notion directed users to export drafts and scheduled emails by September 21, as these items will not automatically transfer to other applications. The company provided guidance for preserving email configurations, noting that users can export snippets and auto-labeling instructions for use elsewhere. Existing custom agents managing email will continue to function, and Notion stated that email connections within Notion will remain operational.

Notion also flagged requirements for organizations operating in regulated environments. Those relying on HIPAA-compliant coverage should transition away from Notion Mail by June 30. The shutdown represents the latest reduction in services descended from the Skiff acquisition, which brought the encrypted email provider’s 2 million users and technical infrastructure into Notion’s portfolio. Though Notion Mail operated as a Gmail client without end-to-end encryption, it maintained connections to Skiff’s founding team and infrastructure. Despite discontinuing this email product, Notion indicated it may continue applying other productivity concepts and resources gained through the Skiff acquisition to compete against rivals such as Google Workspace.
