AI email client

An AI email client that isn't only for Gmail.

Most of them are built on the Gmail API and stop there. AI Emaily drafts your replies in the voice you set across Gmail, Outlook, iCloud, Fastmail, Proton and any IMAP account — on web, Mac, Windows and iPhone. One client, every mailbox, and the reply already written.

    Can you confirm the migration date before I take this to the board on Thursday?

“Thursday works. We're holding the migration for 14 November so the finance close isn't in the same week — happy to walk the board through the rollback plan if that helps.”

Approve & send Edit

undo · audited · nothing sent without you

For people with more than one email address — founders, agencies and client services, consultants, anyone whose work address and personal address aren't on the same provider. Not a bulk-email sender, not a helpdesk. The client you actually write in.

See it work

Two minutes of an inbox answering itself.

Connecting an account, the morning brief, a reply drafted and approved. No slides — the actual product.

01Why most of them disappoint

The AI is rarely the problem. The reach is.

Most AI email clients only speak Gmail.

They're built on the Gmail API, so that's where they end. If one of your addresses is Outlook, iCloud or an IMAP box on your own domain, the clever part simply doesn't reach it — and you keep a second app open forever.

“AI” usually means a summarise button.

A summary tells you what a thread said. You still have to write the answer. The work was never the reading — it was the two hundred words you owe someone by Friday.

The good ones are Mac-only, or web-only.

You work on a Windows machine at the office and a phone on the train. A client that exists in one of those places is a client you use in one of those places.

02Four levels of AI

Not all AI in an inbox is the same AI.

“AI email client” is claimed by products that do very different amounts of work. This is the ladder, and where each one actually stops.

Level 0

Search and sort

Gmail, Outlook, SaneBox

Smart filters, priority inboxes, semantic search. Useful, but no words get written.

Level 1

Summarise and suggest

Most “AI” inbox features

Thread summaries and three-word quick replies. Fine for “thanks, got it”, useless for the reply that matters.

Level 2

Drafts a full reply

Shortwave, Superhuman, AI Emaily

Writes the whole message from the thread and your instructions. You read it, adjust it, send it.

Level 3

Acts, within rules

AI Emaily

Tracks what's owed, stages follow-ups, and — where you allow it — sends without being asked each time. Undo and audit on everything.

03How it works

Three steps, and the third one is the point.

01

Connect every mailbox — under two minutes

One-click OAuth for Gmail, Outlook and iCloud, plus presets for Fastmail, Proton and any IMAP host. They merge into one inbox with one search across all of them. Nothing is migrated; your mail stays where it lives.

02

Set your voice and your rules — once

A tone, a sample of how you actually write, and profiles for the clients and people who matter. That's what it drafts from. Then you decide what it may handle alone and what always waits for you.

03

Work an inbox that's already half-answered

A brief of what genuinely needs a human, with replies drafted underneath. Approve, edit, or ignore. Nothing sends without you until you say it can.

04Mac, Windows, web, phone

Wherever you actually work.

Same account, same inbox, same drafts. Approve on the phone and it's gone from the desktop queue.

Web

Any modern browser — nothing to install.

macOS

Native desktop app, Apple silicon and Intel.

Windows

Native desktop app for Windows 10 and 11.

iOS

iPhone and iPad, with push.

Android

05What changes

The point isn't a smarter inbox. It's a shorter one.

One client instead of three.

Gmail for work, Outlook for the client, iCloud on the phone — in one window, with one set of rules and one search.

The reply is already written.

Not a summary and not a suggestion. The actual message, in the voice you set, waiting for one click.

Nothing quietly dies in the thread.

It tracks what's still owed a reply and stages the nudge you'd have forgotten by Thursday.

The same inbox everywhere.

Web, Mac, Windows and iPhone stay in step, so approving three drafts on the walk home actually clears them.

06Control

You stay at the helm.

A client that can write on your behalf has to earn it. More detail on the security page.

You approve every send

In Copilot mode nothing leaves your account without a click from you. Autopilot is opt-in and only ever acts inside the rules you write.

Undo and an audit trail

Every action the agent takes is reversible and recorded. You can always see what it did, when, and why.

Never trained on your mail

Zero-retention with the model providers, and your email is never used as training data. Bring your own key on the higher plans if you'd rather it never touch ours.

Your mail stays with your provider

We connect with minimum OAuth scopes. Nothing is migrated into a walled garden, so there's nothing to extract if you leave.

08Before you commit

Six questions worth asking any AI email client — including this one.

01

Which mailboxes does it actually support?

The question that decides everything else. A Gmail-only client solves a fraction of the problem the moment one of your addresses lives elsewhere — and most people's second address does.

02

Does it write, or does it summarise?

Ask the demo to produce a finished reply to a real thread, not a bullet summary. The gap between those two is the entire value.

03

Where does the voice come from?

If a tool claims to know your voice without you telling it anything, ask what it read to get there. Ours is what you set — tone, a writing sample, per-client profiles.

04

What can it do without asking?

Anything that can send on your behalf needs an explicit approval step, an undo, and a log. If a product can't show you exactly what it sent and when, that is the answer.

05

Which platforms are shipped — not planned?

“Coming soon” on the platform you live in is the same as no. Ours: web, macOS, Windows and iOS today; Android is still in build.

06

What happens to your mail if you leave?

A client that connects to your accounts leaves nothing stranded. A client that imports your mail into its own store is a migration you'll have to undo.

The things people ask first.

An email app where the AI is the point rather than a side panel — it reads the threads as they land, decides what matters, and writes the replies you'd otherwise type. The better ones also track what's still owed an answer and stage the follow-up.

The category splits sharply on two things: how far the AI goes (search → summarise → draft → act), and how many of your mailboxes it can reach. Most tools that market themselves this way are strong on the first and Gmail-only on the second.
