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

Notion is shutting down its email app, built on the foundation of the encrypted email service Skiff, which it acquired in early 2024. According to Ars Technica, the decision stems from user data showing that the vast majority of Notion's customers now rely on AI agents to handle email tasks instead of a dedicated email client. The app never reached the adoption required to justify continued development, as users increasingly delegate email management to AI-driven workflows. For developers and solopreneurs building with AI, this move underscores a broader shift: users are moving away from traditional applications toward agentic systems that automate communication. Rather than building another email interface, Notion is refocusing on its core platform and AI features—a pragmatic pivot that reflects where the market is heading.
