Notion is pulling the plug on Notion Mail, the AI-enhanced email client it launched just over a year ago. The service will go dark across web, desktop, and iOS on September 22, marking the final chapter in a product lineage that traces back to the company’s acquisition of encrypted email startup Skiff.
The reason is striking: more than 50% of Notion Mail users now manage their email without ever opening their inbox. They’re using AI agents to handle workflows instead.
From Skiff to Notion Mail to nothing
Notion acquired Skiff, a privacy-focused email and productivity startup, on February 9, 2024. Skiff had built a small but devoted user base around encrypted email, with @skiff.com addresses and some limited crypto-adjacent features baked into the platform.
Within a year of the acquisition, Notion shut down Skiff’s standalone email services. Users got forwarding capabilities through February 2025, then the lights went off.
