Email and calendars for Swiss companies, at your own domain.
Every person gets a mailbox with a calendar, the team gets shared mailboxes such as info@, where several people write one reply at the same time. All of it works in the browser, in Outlook, in Apple Mail and on the phone. The messages are stored encrypted in Geneva.
EMX is in beta. Mailboxes, shared mailboxes, calendars, contacts, the web client, every mail app over IMAP and SMTP, calendar and contacts apps over CalDAV and CardDAV, the API and the webhooks work today; more features are being added.What is not included yet

What you get every day
Mailboxes at your domain
An address for every person, plus groups and aliases without a mailbox of their own. Your current addresses stay as they are.
Calendars and contacts that belong to the mail
Events in the browser, invitations answered right in the message, address books with your company's directory, and CalDAV and CardDAV for Apple Calendar and Contacts, Thunderbird and the phone.
A fast web client
Conversations, search on the server and a key for everything. Ten themes in light and dark, one that follows the system, and the interface in English, German, French and Italian.
Every mail app
Outlook, Apple Mail, Thunderbird and the phone's mail app over IMAP and SMTP, with an app password per device. The web client also installs as an app, with notifications.
Quiet from strangers
The screener sets aside mail from senders you have never written to, until you let them in once. A spam filter works on incoming and outgoing mail.
Administration in one place
People, domains, shared mailboxes and the subscription, with a record of every change. When someone leaves, the mailbox becomes a shared mailbox or goes to a colleague.
For teams: one mailbox, several hands
Shared mailboxes such as info@ or office@ cost nothing extra. Whoever works in one sees what the others are doing.
One reply, written together
Several people write a draft of a shared mailbox at the same time. Each sees the others' carets with their names and who is typing; recipients and subject stay the same for everyone. What is typed while offline is not lost.
Rights per person
Read, write, delete, send as and manage, given one by one. Shared mailboxes also appear in Outlook and Apple Mail.
Snippets for the team
Type ;; or / at the start of a line to insert your own snippets or the shared mailbox's, with the recipient's name already filled in.
A calendar that works with the mail
Every person and every shared mailbox has calendars. They are part of the plan and need no second sign-in.
Events in the browser
Day, three days, week, month and agenda. Drag over free time to make an event, drag to move or lengthen it; for a series, choose this one, the following ones or all.
Invitations in the mail
An invitation shows its time in your time zone and what else you have then, with Accept, Maybe and Decline right in the message. Answers update the organiser's event.
Free and busy
While inviting, you see when colleagues are busy, without seeing their events.
In every calendar app
Apple Calendar, Thunderbird and other calendar apps sync over CalDAV, and the contacts over CardDAV. The Apple profile sets up mail, calendar and contacts in one step.
Nothing goes out by accident
Undo send
After Send, the message waits on the server for a few seconds, ten unless you set otherwise, up to thirty. Until then, Undo brings it back as a draft.
Send later
The message goes out at the time you choose, even if nobody is signed in then. Under Scheduled you see what is waiting and change it.
Reminders when nobody answers
If no reply comes within 1 to 14 days, your message is back on top of the inbox.
Forgot the attachment?
When your text mentions an attachment and no file is there, EMX asks before sending, in English, German, French and Italian.
Privacy and location
EMX runs on servers we rent from providers in Switzerland and the EU. What is where is named here.
| Messages and attachments | Geneva, Switzerland, stored encrypted |
|---|---|
| Database (mailboxes, folders, calendars, contacts, settings) | Frankfurt, Germany; copies in Nuremberg and Paris |
| Sealed mailboxes | Where your organisation allows it, encrypted to a key only the person's devices open; then we cannot read them either |
| Contract | Krauss Software, Oberägeri ZG, under Swiss law, with a data processing agreement |
Move without losing mail
Copy your old mail
The move fetches every folder from your current provider over IMAP, with dates and flags, nothing twice. A second run fetches only what arrived since.
DNS, checked live
EMX shows every record needed and checks it in DNS, what was found beside what is expected. An open domain checks itself every 45 seconds until everything is right.
With Cloudflare or Domain Connect
If your DNS is at Cloudflare, EMX makes the records with an API token after you have seen every change; the token is not kept. With supported DNS providers, Domain Connect does it.
Does EMX suit your company?
EMX suits you if
- you need email and calendars, not a whole suite.
- several people answer info@ or office@.
- your messages should be stored in Switzerland and the contract should follow Swiss law.
- your team wants to keep Outlook, Apple Mail or the phone.
Something else suits you better if
- you want documents, file storage and video calls from one place, as with Microsoft 365 or Google Workspace.
- you need Exchange ActiveSync.
- you require a legal archive or an ISO 27001 certification.

Frequently asked questions
Does Outlook work?
For mail, yes, over IMAP and SMTP, shared mailboxes included. Outlook does not speak CalDAV: use the calendar in the web client, or subscribe to it in Outlook, read only, through its secret feed address. EMX does not offer Exchange ActiveSync.
Can I keep my address?
Yes. EMX works with your own domain; the addresses stay as they are.
What do shared mailboxes cost?
Nothing extra. Team is paid per person.
Are there calendars and contacts?
Yes. Calendars in the web client, with invitations in the mail and over CalDAV in calendar apps. Contacts in the web client, with your company's directory, and over CardDAV in Apple Contacts, Thunderbird and on the phone.
How do I leave again?
At any time: an export as a file per folder, the calendars as .ics files, the contacts as .vcf files, or over IMAP. After cancelling, 30 days to export follow.
