The service, launched in April 2025 and built by former Skiff employees, will be discontinued as Notion focuses on AI agents for email workflows. User data will remain in Gmail.", "body_md": "In February 2024, [Notion bought Skiff](https://arstechnica.com/gadgets/2024/02/encrypted-email-service-skiff-gets-acquired-will-shut-down-in-six-months/), an encrypted email and productivity software startup. Within a year, Notion shut down Skiff’s email service (taking @skiff.com email addresses with it). And in April 2025, the San Francisco-based company released Notion Mail, a Gmail client primarily built by people who joined Notion through the Skiff acquisition. Today, Notion announced that it’s shutting down Notion Mail, effectively killing what little remained of Skiff email.\n\nIn an [X post (](https://x.com/NotionMail/status/2070177267074977991?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E2070177267074977991%7Ctwgr%5Efe47482444044d33c72a3a07a70a065ab8d2fb45%7Ctwcon%5Es1_c10&ref_url=https%3A%2F%2F9to5mac.com%2F2026%2F06%2F25%2Fnotion-shutting-down-its-ai-powered-email-client-including-mac-and-ios-apps%2F)first spotted by [9to5Mac](https://9to5mac.com/2026/06/25/notion-shutting-down-its-ai-powered-email-client-including-mac-and-ios-apps/)) today, Notion said that it will shutter the Notion Mail “inbox across web, desktop, and iOS on September 22.”\n\nThe post claimed that most Notion users don’t use email clients anyway and instead rely on AI agents to handle their electronic correspondence. It reads:\n\nWe launched Notion Mail with a belief that your inbox should think like you—more personal to how you work and over time, more capable with AI.\n\nAs Notion agents have gotten more capable, we’ve seen more users hand off email workflows to them. Today, more than half of Notion Mail users manage emails without ever opening their inbox. So, we’re going all in on using agents to run your inbox.\n\nNotion noted that most user data will stay in Gmail.
