One inbox
for your
domain

Every message to @company.com lands in the domain's inbox. Each person builds a view over it, and rules route the rest.

Let rules sort the domain's inbox

Teams stopped mailing files to each other once shared drives arrived, and forwarding rules go the same way once every message lands in one inbox. Write a rule once and it runs on every message after that.

Filter the inbox down to your work

A view filters the domain's inbox down to your part of it: support tickets, mentions, one customer or one country. The view belongs to you and the mail stays shared.

How views work

Send mail to a person, an agent or a webhook

A rule sends the message to a colleague, to an on-device AI agent that drafts the reply, or to a webhook that updates your CRM.

Run it on your own servers or in your cloud

Run the whole stack in your data centre or with an EU host. On sealed domains the client encrypts mail with keys you hold.

Pricing

Pay per organisation, not per seat

You pay when we run the mail server for your domain. Everything else costs nothing: the apps on every platform, and inbox2 over the Gmail, Microsoft 365 or IMAP accounts you already have.

Run your domain from one console

The console holds domains, DNS health, people, routing rules, billing and API keys. It shows what is broken before anyone forwards you a bounce.

DNS checks every 5 minutesWe check each domain's MX, SPF, DKIM and DMARC and give you the exact record to paste when one is missing.

Keys and devicesEach integration gets its own API key, and you can revoke any linked phone or desktop in one click.

Keep your mail under your own control

inbox2 runs on your servers and encrypts on the client. Send through your own servers, keep AI triage off or on the device, and your mail never reaches a US processor. Billing runs through Stripe and never sees your mail.

  • Hosted domains run on server-side MX, or the apps work client-side over your existing tenant
  • The client encrypts with libsodium, and your organisation holds the keys
  • Self-host, send through your own servers and keep AI on the device, and your mail stays with you
  • Your ops team deploys it from a single container image

The apps for macOS, Windows, Linux, iOS, Android, the browser and the terminal all run the same Rust core over a local file on your own disk. They work with the accounts you already have, whether or not your domain lives here. Every one of them is free.
