Notion ends Notion Mail, shutters Skiff-influenced email Sept 22

Notion will shut Notion Mail across web, desktop, and iOS on September 22, the company announced, effectively ending the last remaining piece of the Skiff email product that Notion acquired. Notion said most users have stopped opening the inbox and instead let Notion agents handle their email workflows, and it urged users to export drafts and scheduled messages by September 21.

What exactly is being shut and when?

Notion is closing the Notion Mail inbox on September 22 across web, desktop, and iOS, and it warned users to export drafts and scheduled emails by September 21 because those items will not automatically carry over. The company also said most user data will remain in Gmail: "When the Notion Mail inbox shuts down, your email history will stay exactly where it is in Gmail," the support page reads. Organizations relying on regulated workflows should note a separate timeline: if you rely on HIPAA coverage, Notion asks you to plan to transition off Notion Mail by June 30, 2026.

Why is Notion killing Notion Mail?

Notion says user behavior changed as its AI agents became more capable: "more than half of Notion Mail users manage emails without ever opening their inbox," the company wrote, and it observed that many users hand off email workflows to agents. Notion launched Notion Mail in April 2025 as a Gmail client built largely by staff who joined via the Skiff acquisition, but the product did not carry Skiff's original end-to-end encryption focus. Notion framed the shutdown as a pivot toward running inboxes via agents rather than conventional email clients.

What should affected users do now?

Export drafts and scheduled emails by September 21, since those items will not port automatically to other apps. Notion also offers ways to preserve automation and labels: users can save Notion Mail setups, export snippets and auto label instructions, and create a Custom Agent to bring existing rules over. Notion said that if users already run Notion agents to manage email, those agents will continue running and the email connection in Notion will remain in place. The company warned that regulated organizations may need to finish their transition earlier and provided the June 30, 2026 date for HIPAA.

What’s the history here?

Notion bought Skiff in February 2024. Within a year of that acquisition, Notion shut down Skiff's original email service and took @skiff.com addresses with it. In April 2025 Notion released Notion Mail, a Gmail client primarily built by former Skiff staff and on Skiff infrastructure. Skiff had reportedly served 2 million users before the acquisition, and the Notion Mail product lacked the end-to-end encryption emphasis that had been central to Skiff's offering.

Why it matters

The shutdown signals a shift from offering a standalone email client toward treating email as an agent-managed workflow. That change affects individual users who relied on a conventional inbox and organizations with compliance needs. It also closes a chapter on Skiff as an email provider inside Notion: the product built on Skiff infrastructure and by former Skiff executives will cease to operate on September 22, leaving only Notion's agent strategy and whatever productivity integrations Notion continues to develop.

What to watch

Watch whether Notion completes migration tools that preserve users' automation and labels, and whether enterprise customers meet the June 30, 2026 HIPAA transition guidance. Also track whether Notion repurposes Skiff staff and infrastructure into calendar, storage, or agent features rather than rebuilding a privacy-focused email offering.
