Your data is yours. Here is how we prove it.

Your email, files and calendars at email.eu live in open, standard formats you already own — reachable over the same protocols the whole internet runs on. Here is what that means in practice, and why portability is one of the features we are proudest of.

When you put your company's email, files and calendars somewhere, you're trusting that they'll still be yours — not just to read, but to pick up and take with you, in one piece, whenever you like. That sounds obvious. It often isn't. A lot of software keeps your data in a shape only that software can open, so while you can see everything, getting it back out whole is somewhere between a chore and a project.

We built email.eu the other way around. Everything you put in is held in open, standard formats and reachable over open, standard protocols — the same ones the whole internet runs on. Your data isn't visiting our database; it's sitting in your account in a form any tool can read. Here's what that means in practice, and why we think it's one of the most important things about the product.

Your data, in formats you already own

Not "exportable in principle" — already standard, right now, while you're using it.

WhatThe standard it's in
MailIMAP. Open it in any mail client — Apple Mail, Outlook, Thunderbird — and it's all there, every message and folder.
CalendarsCalDAV. Connect any client and your calendars sync straight in.
ContactsCardDAV. Same — any client, your whole address book.
FilesOrdinary files. Use them in the browser, and download them, folders and all, whenever you like.
Documents.docx, .xlsx, .pptx — the real files, stored as standard files from the moment you create them.
Your domainYours, at your registrar. We host your mail; we never hold your name.

The documents row is the quiet star of that table. A Google Doc isn't really a document — it's a row in Google's database that only google.com can open, and you find that out the day you try to take it elsewhere. Our office suite works in .docx, .xlsx and .pptx natively, so the file on disk is the standard file today, while you're a happy customer. Nothing proprietary goes in, so nothing has to be untangled later.

The same openness is what makes coming in easy, too: because your old provider speaks these protocols, our weekend migration just reads your mail over IMAP and copies it across. Open standards are the on-ramp and the off-ramp at once.

(One honest note, since we'd rather you hear it from us: there's no single "download everything" button yet. You take each part the standard way — mail over IMAP, calendars and contacts over Cal/CardDAV, files through the web — and the file copy is hands-on. Each step is well-trodden; we'd just like to make it one click, and we're working toward it.)

Why we made portability a feature, not a footnote

Most companies treat the exit as something to make quietly difficult — the longer you stay, the more it would cost to move, until one day they don't really have to keep earning your business. We decided that's the wrong thing to build, for two reasons that both point the same way.

The first is that you can't honestly promise people sovereignty and then be the one company they can't get their data back from. Our whole pitch is your data, in the EU, under your control — and "your control" has to include the freedom to take it elsewhere, or the headline doesn't mean anything. Portability isn't a concession to that promise; it's the proof of it.

The second is about what it does to us. If your data is always yours to move, then the only thing keeping you here is that email.eu is genuinely good — fast mail, a clean migration, support that actually answers. That's a much better thing to be kept by, and it points every incentive we have at the work instead of at the lock. We'd rather win on the product each month than on the cost of leaving.

So when we say your data is yours, we mean it the strong way: yours to use, yours to keep, and yours to take. The open standards above are how you can check that for yourself, the same way the subprocessor list lets you check who can touch your data while it's here. Claims you can verify are the only kind worth making — and this is one of the ones we're proudest of.
