Notion Mail alternative: where to go next

Notion Mail shut down on 22 September 2026. Your email is fine: it lives in Gmail and always did. What you lost was a window and a setup, so what you need is a Notion Mail alternative, not a rescue plan. Shortwave for the AI, Superhuman for the speed, Gmail itself if you want free, Conduit Mail if you want a familiar window and plain-English rules.

Disclosure before anything else: we make Conduit Mail, one of the clients listed below, and it is in early access. That is a reason to read the last section with a raised eyebrow, not the first six. If Shortwave, Superhuman or plain Gmail fits you better, this post says so.

What happened to Notion Mail?

Notion Mail is discontinued. Notion’s own help page is the primary source: Notion Mail inbox is going away. It said “The Notion Mail app for iOS, desktop, and web is going away for everyone,” and “All Notion plans are affected.” The app shut down on 22 September 2026, across web, desktop and iOS, on every plan.

The export deadline was 21 September, the day before. If you pulled out your drafts, scheduled emails, snippets and auto label instructions before it closed, you have them. If you didn’t, Notion said unsaved drafts and scheduled emails would be permanently deleted, so there is nothing left to rush and nothing left to save.

Your mail itself was never in play. Notion’s page put it plainly: Notion Mail “always synced two ways with Gmail, so every email you received or sent in Notion Mail also exists in your Gmail inbox.”

Every competitor price below was checked against that vendor’s own page on 8 September 2026. Prices move; check the links before you spend anything.

What you actually lost when a mail client shut down

A mail client is a window. The account behind it belongs to your provider, and in Notion Mail’s case that provider was Google. That split decides what survives.

Safe, because it lives on Gmail’s servers:

• Every message, thread and attachment you ever sent or received
• Your labels, including anything Notion Mail applied through auto labels
• Your address, your contacts, your signature-on-file, your filters if you ever made them in Gmail itself

Gone, because it lived inside the app:

• Snippets and templates you never exported
• Auto label instructions, which were Notion Mail’s rules
• The keyboard muscle memory, which nobody thinks to count until the first morning without it

The second list is the one you spent months building and the only one with no backup. It is also the shorter list, which is the good news.

Rebuild these three things first

Don’t try to reconstruct your old client. Reconstruct the three things you used every day.

1. The sort. Write down the piles you actually looked at. Yours might be three or four: people who expect an answer, things with a deadline, receipts, and everything else. Whatever your new client calls them, that list is your setup, and it takes five minutes to write down.

2. The rules. The auto label instructions are the highest-value thing you lost, because they were doing work while you slept. Rewrite the five or six that mattered. Skip the long tail; you will not miss it.

If you are rebuilding one rule per sender, one per newsletter and one per retailer, count them before you pick a plan. In Conduit, the Free plan allows five automation rules and unlimited rules are a paid plan. Five goes fast.

3. The two or three habits. Archiving with one key, snoozing to tomorrow morning, whatever your version was. If a candidate client can’t do those in one keystroke, you will feel it on day two.

One thing to expect from any client’s rules, including ours: rules run forward. They fire on mail as it arrives and do nothing to the mail already sitting there. For the backlog, do it in Gmail: search for the sender or the term, select all, then apply the label or archive in bulk. We wrote up the limit and the workaround in what rules don’t do yet.

The Notion Mail alternatives worth switching to

Pick on what you actually liked about Notion Mail, not on whose feature list is longest. Four destinations cover most people, and the first three are not ours.

If you liked the AI: Shortwave or Gemini

Notion Mail’s pitch was AI doing the sorting and the drafting. Three clients still do that job, and the gap between the cheapest and the dearest is about a hundred dollars a month per seat.

Shortwave is the closest thing to a direct swap: AI search and AI drafting are the center of the product, not an add-on. Its pricing page lists three paid seats: Business at “$30 per seat / month,” Premier at “$45 per seat / month,” and Max at “$120 per seat / month,” with a 14-day trial and no free tier (checked 8 September 2026). If AI search across years of mail is the feature you cannot give up, this is where to look first.

Gemini in Gmail is the cheapest way to find out whether you want AI in email at all, because you are already in Gmail. Google’s help page on Gemini features in Gmail says personal-account users in the US can use a set of Gemini features in Gmail at no charge, while asking your inbox questions through AI Overviews is for Google AI Pro and Ultra subscribers. No migration, no new window, no new keyboard shortcuts.

Conduit Mail is ours, and it gets its own section below rather than a paragraph here where the comparison is rigged.

If you liked the speed: Superhuman

If what you actually liked was moving through mail quickly with your hands on the keyboard, the AI conversation is a detour. Superhuman is the keyboard-first client most people mean when they say keyboard-first.

The speed is the keyboard: a command palette, a shortcut for nearly every action, and a split inbox that separates mail which needs you from mail that doesn’t. AI drafting arrived later and sits on top of that rather than being the center of the product. Confirm the current feature list on the vendor’s page before you commit.

Superhuman Mail lists Starter at $30 per month, or $25 per member per month billed annually, and Business at $40 per month, or $33 annually. Enterprise is priced by sales (checked 8 September 2026). Business is the tier where the AI features and the MCP server live.

If you want a free tier: Spark

Spark by Readdle is the option with a real free plan, which matters if Notion Mail was bundled into something you were already paying for and you don’t want a new line item. Its pricing page lists Free at “$0,” Plus at “$10 / month per user,” and Pro at “$20 / month per user,” with roughly 17% off annually (checked 8 September 2026).

If you want a familiar window and plain-English rules: Conduit Mail

Conduit Mail is what we build, and it is in early access, so read this section knowing that. It is a three-panel window that works the way email clients have always worked, with the AI in a side panel rather than in front of the mail.

What is relevant to someone coming off Notion Mail:

• Rules you describe in a sentence. Type what you want and you get a real automation back: a trigger, conditions and an ordered list of actions you can open and edit. That is the closest Notion Mail replacement for auto label instructions. More on how it works in email rules in plain English.
• New mail gets sorted into six categories (People, Notifications, Social, Newsletters, Promotions, Transactions). Honest caveat: it still miscalls the edges. Use it as a starting arrangement and lean on rules for anything you actually need filed correctly.
• An AI panel you invoke with ⌘K for summaries, drafts, replies and search, showing each tool call as it runs, and asking you to confirm before it acts on your behalf.
• Natural-language search. Type a sentence and Conduit turns it into filter chips you can edit. The sentence is interpreted by Claude; the filters then run against mail already on your device. Nothing is indexed on our servers.
• Conduit’s hosted MCP server (Plus and up) at connect.conduitmail.app/mcp, if you want an agent — Claude, Codex, ChatGPT, or any other MCP client — reading and drafting against your mail.

Where we are honest about the gaps: this is early access, Gmail is the provider everything is built around first, there is no published desktop release and no native iOS or Android app. Mobile today is the installable web app. The current status of all of that lives on /download, which we keep up to date, rather than in a blog post that ages.

On privacy, the short version: mail passes through our servers on its way to you, it isn’t stored there, and our database has no table for your email.

What we do store:

• Account identity, plus encrypted OAuth tokens and mail credentials
• Your rules, notes and settings
• Short writing samples from sent mail, so drafts sound like you on every device

All of it is visible in Settings and yours to turn off or delete. Your email is never used to train AI models. Not by us, not by Anthropic — their commercial API terms forbid it, and Google’s restricted-scope rules bind us to it in writing.

One thing runs without you asking: the category sorter. On the Free plan it stays entirely on your device and sends nothing. On paid plans, the messages the local classifier is unsure about get a second look, and the sender, subject, a short preview, a few mailing-list headers and a category hint go to Anthropic, never the body.

Pricing, for planning purposes only, since billing is not open during early access: Free is $0 with five rules, Plus will be $9/month with unlimited rules and MCP access, Pro will be $27/month adding scheduled-rule creation. Be clear-eyed about that last one: you can build a scheduled rule on Pro, but the execution side is not wired up yet, so a saved schedule acts on nothing today. Every plan includes the whole mail client and unlimited email accounts. The details are on /pricing.

How to switch in an afternoon

1. Write down your three lists before you install anything: the piles you looked at, the rules you had, the two or three habits.
2. Check Gmail first. Your labels are already there. Whatever a new client shows you starts from them, so tidy the labels once and every candidate looks better.
3. Pick one client and give it a week. Two clients in parallel means you rebuild nothing properly and blame the wrong one.
4. Rebuild rules on day one, not day five. They are the only part that compounds. Everything else you can learn as you go.
5. Clear the backlog separately. Bulk-select in Gmail search, then let the new rules handle everything from that day forward.

If plain-English rules are the part you want back first, request early access at conduitmail.app.

Still deciding? /pricing has the plan limits, and what the AI actually touches inside Gmail has the feature-by-feature version.
