Addresses for everyone, members never counted as seats.
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.
End-to-end encrypted
OpenPGP keys made in your browser. Mail to an OpenEmail address with a published key is sealed before it leaves the tab, and we cannot read it.
readable where it lands
Wire transfer approved, details attached.

Multiple domains
Add as many as you own, subdomains too, and every address on them is real.

AI first
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.

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.
Ask your inbox
Plain language, in a sidebar that can act: open a thread, summarise it, label it, archive it, draft the reply and send it.
who is chasing me about the invoice?
Nina, twice this week. The second one is marked urgent.

She agreed to the renewal, asked to revisit seats in Q1.
MCP server
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.

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 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.
