However, Notion urged users to export drafts and scheduled emails by September 21, since those won’t automatically carry over to an alternative app. Notion noted that users can also save their Notion Mail setups and “export your snippets and auto label instructions to use elsewhere.”

“If you have auto label set up in Notion Mail, you won’t have to rebuild it. Create a Custom Agent in a few clicks, and we’ll bring your existing rules over for you,” the X post explained. “And if you’re already running Notion agents to manage email, they’ll continue running. Your email connection in Notion stays in place.”

Organizations that relied on Notion Mail in a regulated environment might have to transition from Notion Mail earlier.

“If you rely on HIPAA coverage, you should plan to transition off Notion Mail by June 30, 2026,” Notion’s support page reads.

Skiff reportedly served 2 million users, giving rivals like Proton Mail a run for their money before the Notion acquisition. As a Gmail client that didn’t support end-to-end encryption, Notion’s AI-centric approach to email lacked the privacy focus that Skiff carried as an email provider. Still, Notion Mail was built with Skiff’s infrastructure and by former Skiff executives, making its impending demise feel like a sort of swan song for Skiff.

Although Notion is killing its Skiff-influenced email client, it may continue leveraging the human resources and other productivity ideas (around calendars and storage, for instance) gained through its Skiff acquisition as it tries to compete more strongly against rivals like Google Workspace. Notion, however, has strayed from releasing direct follow-up products to Skiff’s portfolio.
