Notion
Notion Mail, the AI email client Notion launched in April 2025 on the technology from its Skiff acquisition, is being retired; the inbox closes across web, desktop, and iOS and Notion-Mail-only data is deleted unless exported first
left 22 Sept 2026
Quick answers
- Is it true that Notion Mail is shutting down — the email client closes 22 September 2026 across web, desktop, and iOS?
- Yes — and the date has already passed (22 Sept 2026). This affects anyone who used Notion Mail as their day-to-day email client on web, desktop, or iOS.
- When did it take effect?
- 22 Sept 2026 (already passed). Verified against the vendor's own announcement.
- What should I use instead?
- Your mail itself needs no migration: because Notion Mail was a front-end over a synced Gmail account, every message remains in Gmail and you can keep working in Gmail's own web/mobile apps or point any standard IMAP/Gmail client at the same account.
What this means for you
This affects anyone who used Notion Mail as their day-to-day email client on web, desktop, or iOS. Notion announced on 25 June 2026 that it would shut the client down on 22 September 2026 and focus instead on agent-driven email, saying more than half of Notion Mail users had stopped opening the inbox and were letting AI agents read, triage, and reply for them. Because Notion Mail synced bidirectionally with Gmail, the actual email history is safe — it lives in the connected Google account and is reachable through Gmail or any other client. What is lost is anything that existed only inside Notion Mail: drafts, scheduled emails, saved snippets, and auto-label rules. Notion set 21 September 2026 as the last day to export those, and warned that anything not saved by then is permanently deleted when the inbox closes the next day. There is no in-place successor client to move to — Notion is redirecting the effort into its AI agents rather than shipping a replacement inbox.
Where to go
Your mail itself needs no migration: because Notion Mail was a front-end over a synced Gmail account, every message remains in Gmail and you can keep working in Gmail's own web/mobile apps or point any standard IMAP/Gmail client at the same account. What did need action before 21 September 2026 was exporting the Notion-Mail-only artifacts — drafts, scheduled sends, snippets, and auto-label instructions — which Notion said would be permanently deleted at shutdown; if you missed that window, those are gone. Choose any mainstream mail client to replace the interface (Gmail's own apps, Apple Mail, Thunderbird, or another provider) — this is a client retirement, not a loss of the underlying mailbox.
- Gmail's own web and mobile apps, or Apple Mail — the mailbox Notion Mail synced with is unaffected
- Any standard email client (Thunderbird, or another IMAP/Gmail-compatible app) pointed at the same account
Notion is retiring Notion Mail, the email client it launched in April 2025 on the technology it picked up when it acquired the encrypted-productivity startup Skiff. On its official help page, “Notion Mail inbox is going away: what to do next”, the company set the shutdown for 22 September 2026, closing the inbox across web, desktop, and iOS. Notion announced the plan on 25 June 2026, saying that more than half of Notion Mail’s users had stopped opening the inbox at all — they had handed it to AI agents to read, triage, draft, and reply on their behalf — and that the company would “go all in” on agent-run email rather than keep maintaining a standalone client.
For most users this is a client retirement, not a loss of their mail. Notion Mail was a front-end over a Gmail account it synced with bidirectionally, so the email history itself stays in Google’s servers and remains reachable from Gmail or any other client pointed at the same account. What disappears is anything that lived only inside Notion Mail: drafts, scheduled emails, saved snippets, and auto-label rules. Notion set 21 September 2026 as the last day to export those and warned that anything left unsaved is permanently deleted when the inbox closes the following day.
There is no drop-in replacement inbox to move to — Notion is folding the effort into its AI agents instead of shipping a successor client. The migration is therefore back to a mainstream mail app: keep the same mailbox in Gmail’s own web and mobile apps, in Apple Mail, or in any standard IMAP/Gmail-compatible client such as Thunderbird. The one irreversible piece was the export deadline; if the Notion-Mail-only drafts, scheduled sends, snippets, and label rules were not saved by 21 September 2026, they did not survive the shutdown.
A note on how we sourced this: Notion’s help center renders its articles in the browser with JavaScript, so our automated fetcher sees only the page shell rather than the article text. The dates and details above come from the official article’s own indexed content and are corroborated by contemporaneous independent reporting. If any of them is later restated differently by Notion, this entry will be corrected and the change logged here.
Entry changelog
- — last reviewed.
- — Entry created from Notion's official help article "Notion Mail inbox is going away: what to do next". The shutdown date (22 September 2026), the 25 June 2026 announcement, the 21 September 2026 export deadline, the affected platforms (web, desktop, iOS), the Gmail-sync data-retention behaviour, and the permanently-deleted Notion-Mail-only data (drafts, scheduled emails, snippets, auto-label rules) are all drawn from that page. Note on sourcing: the Notion help center is a JavaScript-rendered single-page app, so our automated fetcher receives only the page shell; the facts above were confirmed against the official article's own indexed content and corroborated by independent contemporaneous reporting (9to5Mac, Engadget). Status recorded as passed — the shutdown date is already behind us. No detect: fingerprint: this is a hosted email client, with nothing a codebase would contain.
