The first AI-native email infrastructure
Emails that belong
to you, entirely.
Email infrastructure for businesses, AI, agents and personal email. Built for scale, privacy and control. Everything email should have had from day one.
Everything included
Everything email should have.
Nothing it shouldn't.
Search, rules, snoozes, templates, tracking, scheduling and an AI that has read every thread.
OpenPGP keys made in your browser. Mail between OpenEmail addresses is sealed before it leaves the tab, and we cannot read it.
Wire transfer approved, details attached.
Add as many as you own, subdomains too, and every address on them is real.
A chat that can act on your mail, drafts in your own voice, and agents over MCP.
I hope this email finds you well. I wanted to reach out regarding the proposal we discussed last week. Our approach is designed to be robust, scalable, and straightforward to adopt. Moreover, it is not just about the tooling, but about the outcomes it enables for your team. In conclusion, please do not hesitate to reach out if you have any questions.
Share an address with a teammate and it lands in their own inbox. Roles say who may do what.

Website builders, developer tools and APIs that run their email on OpenEmail today.
AI-first, agent-ready
Ask your inbox.
It already knows.
It answers from mail you already have and drafts in your voice. Your agent gets the same mailbox over MCP.
Plain language, in a sidebar that can act: open a thread, summarise it, label it, archive it, draft the reply and send it.
Point Claude, or any MCP client, at api.openemail.uk/mcp and it can read threads, search, label and send. The same mailbox has a REST API, a typed SDK and a command line, all live and documented.
A rolling profile built from your own sent mail: how long your sentences run, how you open, how you sign off. Every draft is written to match.
52 signals, learned from your sent mail
What your mailbox already knows, kept as facts rather than as a search: who owns what, what renews when, and which thread said so.
Triage, labelling, summaries and first-pass replies, done before you open the tab. Every action reversible, every drafted reply still a draft.
Write the note; OpenEmail writes the subject. Or hand it a line of intent and get the whole body back.
written from the body you already typed
Anything you can do in OpenEmail, an agent can do. Same account, same scope.
One platform
Cancel the stack.
Keep the mail.
A mailbox, a team plan, the fast client, aliases, forwarding, who opened it and your product's sending API. Seven invoices, seven logins, one job.

Instead
Who it is for
One mailbox.
Four ways in.
The same product underneath, described for the person reading it. Start wherever you recognise yourself.
What you stop paying
Compare the bill.
Move the slider.
The mailboxes multiply by headcount and the sending tools by volume. We sell four plans, so the tenth teammate costs what the second did.
most mailboxes bill per seat; two or more needs Starter
ours steps at 1, 50 and 500; Proton, HEY, Resend and Fastmail charge more
Resend and Mailchimp bill by volume; mailboxes cap it per seat
unlimited on every plan of ours; Proton and Fastmail tie them to seats
Forward EmailTeam
OpenEmailStarter
FastmailBusiness Standard
Google WorkspaceBusiness Starter
SuperhumanStarter + WorkspaceMost of these sell one piece of the job: a mailbox, a sending API, a campaign tool or an app that needs a mailbox from somebody else. The OpenEmail price is the whole job, with mailboxes on your own domains, sending and receiving, the full API and the AI assistant on every plan. So this is not even a fair comparison: every other bar buys one piece, and ours buys all of it.
