Notion Kills Its Skiff-Derived Email App, Going 'All In' on Agents Running the Inbox

Ars Technica·medium signal

Notion is shutting down the email app it built on its Skiff acquisition, saying most users now rely on AI agents instead of a manual client and that it is 'going all in on using agents to run your inbox.' It's an early, concrete example of an acquired product being retired because agentic workflows ate the use case. The signal for builders: inbox/triage is consolidating into agent surfaces, not standalone email UIs.
