Editions & pricing

Free below five users. Four editions above. One licence throughout.

OxiMail is not sold as a subscription to a service we operate — there is no service we operate. You license software that runs on your own machine. Below five users, in an organisation running it for itself, that licence is free. Above, you choose an edition. We are in the middle of rebuilding the price list around this model, so this page describes the shape honestly and the figures come when they are firm rather than as a placeholder we would revise.

The editions

Suite · Most common

Server + Workspace + Sync

Organisations giving people a finished product

What most deployments actually buy.

  • Everything in Essential
  • Workspace web client
  • Chat and video calls up to three
  • Sync desktop agent
  • White-label branding
  • Several domains per instance
Suite + Drive

And the file server

Organisations retiring a NAS or a Samba box

The file server folded into the same machine.

  • Everything in Suite
  • SMB network drive on the office LAN
  • The same files in the browser and in Sync
  • Version history, trash, revocable share links
  • LDAP-synced permissions

Two things sit outside the editions. Modules are bought à la carte on top of any paid edition: the AI assistant and Meet are available, Booking and Notify are in development, Comms and Shield are on the roadmap. And the scaling layer — PostgreSQL, object storage, clustering — exists for deployments past a few thousand accounts and is built as customers fund it; below that, one SQLite-backed binary has been validated to about 2000 accounts and is the right answer.

Operators and partners

Wholesale per mailbox, and no entry fee.

If you operate OxiMail for other people — a hosting company, a managed-services provider, an integrator — you are licensed from the first mailbox, and you buy your mailboxes at a wholesale price. What you charge your own customers is your business, and we do not want to know your client list.

No entry ticket

You do not buy your way into a partner programme. You start at the public price on your first mailbox, with no annual fee to clear first.

Automatic graduation

Your discount follows the total number of mailboxes you run, across all your customers. It moves by itself as you grow — the portal shows you the next step. It is never a negotiation.

Your brand, not ours

White-label the interface. Your customers see your company. An internal instance for your own team comes with being an active partner.

A deliverability kit on day one

The objection that has always killed self-hosted mail: does it land in the inbox. Outbound relay, backup MX, automatic DKIM and DMARC, monitoring, and data-processing paperwork ready to chain from us to you to your customer.

Support

Three support bundles.

Optional — a safety net if you want one, never a dependency you cannot leave.

  • Business-hours coverage
  • Ticket system
  • Priority bug triage

Implementation

One-off, on quote
  • Migration planning and execution

  • Post-cutover stabilisation
FAQ

Common questions.

Why are there no prices on this page?

Because we changed the licensing model and the old figures no longer describe what we sell. Publishing numbers we already know we will revise would waste your time. Ask us and you get a firm figure for your situation within a few business days; the public list follows once it is settled.

What counts as a user?

Someone who can sign in with their own mailbox. Aliases, distribution lists and shared mailboxes without their own login do not count, and there is no limit on them. Anything outside production — testing, evaluation, teaching, research — does not count either.

What happens if we go past five users?

The server tells you. You get an admin banner and a compliance report, and thirty days to sort out a licence. It does not stop delivering mail, it does not disable features, and it does not ask a server of ours for permission to keep running. Enforcement is a contract, never a switch we hold.

What does “fair source” mean, and is it open source?

No, and we will not call it that: open source has a definition and this licence does not meet it. The server source is published and auditable, free below the threshold, and each release converts to AGPL-3.0-or-later four years after it ships. You get the auditability and a contractual ceiling on our pricing power. What you do not get is the right to run it commercially for free.

Do you run a SaaS on oximail.ch?

No — channel-only. We do not operate hosted mailboxes ourselves. OxiMail reaches users through hosters, institutions and partners. For a managed OxiMail, a partner in your region operates it for you.

Can we start small and move up later?

Yes. Moving between editions is a licensing change — the binary and your data stay put. Start free or with Essential and grow into the rest; we arrange a pro-rated transition.
