Notion is shutting down its email client built on Skiff's infrastructure. Users must export drafts and scheduled messages by September 21, but can migrate snippets and auto‑label rules to a custom agent. Existing agents keep running and the email connection stays active.

Regulated customers face a hard deadline; the support page advises anyone relying on HIPAA coverage to transition off Notion Mail by June 30, 2026. Skiff once served two million users and rivaled Proton Mail, yet Notion’s AI‑first email never offered end‑to‑end encryption, leaving privacy concerns.

The service’s demise doesn’t erase the talent and ideas Notion acquired. Former Skiff staff will likely influence calendar and storage features as Notion pushes against Google Workspace. The shutdown marks a clear retreat from direct email products while the company continues to harvest productivity assets.
