Six real options, compared honestly, including the ways our competitors beat us. This guide is published by Email.eu; the bias is disclosed, the facts are dated.
In June 2026 the European Commission adopted a digital-sovereignty package, the European Parliament replaced Google as its default search engine, and Microsoft announced another price increase for July. Meanwhile the US CLOUD Act still applies to American providers wherever your data physically sits, an EU region changes the latency, not the law. Moving off the American stack has gone from a values decision to an ordinary procurement one.
Four questions separate the options below: Is the operator under EU jurisdiction, or just hosting in an EU region? Is it a complete workspace or mail with extras? Can you leave, open protocols, open formats? And who does the work of migrating you?
The full workspace, mail, calendar, drive, docs, sheets, slides, wiki, meetings and chat, operated as one product by one Dutch company (Remails B.V.), hosted on OVHcloud in Paris with an EU-only supplier chain down to payment processing. Built on European open source (Stalwart, Bulwark, La Suite Meet, Authentik), with open protocols (IMAP, JMAP, CalDAV, CardDAV) so any client works and leaving is always possible.
The honest caveats, since this is our own guide: we are the youngest product on this list, our certifications are a published roadmap rather than framed certificates (ISO 27001 targeted 2026), and our editors are web-based, no desktop Office apps. What we do that nobody else here does: migration performed with you by hand, with a mail engine that mirrors Google Workspace, Microsoft 365 or any IMAP server over a weekend.
Best for: SMBs that want Google Workspace replaced with a finished product, not a project, and a human on the phone during the switch.
Watch out for: Young product; compliance certifications still on the roadmap. We publish exactly where each one stands.
The strongest end-to-end encryption in this list, by design and by default, Proton’s zero-access architecture means even Proton cannot read your mail or files. Since March 2026, Proton Workspace bundles mail, calendar, drive, docs, sheets and video meetings into a real suite.
Read the tiers carefully: the widely quoted $6.99 is Mail Essentials, which is mail and calendar with 15 GB. The full suite, with Drive, Docs, Meet and 1 TB, is Workspace Standard at $12.99. The encryption also has structural costs: IMAP works only through their Bridge app on every machine, and there is no CalDAV. Switzerland is a third country under GDPR, strong privacy law, but not EU jurisdiction, which matters for some procurement.
Best for: Teams whose threat model puts maximum encryption above everything else.
Watch out for: Bridge-only IMAP, no CalDAV, Swiss (not EU) jurisdiction. · Detailed comparison →
A mature Swiss hoster with a genuinely complete suite, mail, kDrive storage (generous, multi-terabyte tiers), docs and video, at aggressive prices. kSuite Standard is €1.58 per user per month for 50 GB, Business €6.58 and Enterprise €12.41, and the first year is half price. Twenty-plus years of operating history and its own data centres make it one of the most established independents in Europe.
Like Proton, it is Swiss rather than EU, fine for most companies, a tender-blocker for some public-sector buyers. The product is self-serve: good documentation, but nobody migrates you by hand.
Best for: Price-conscious teams that want lots of storage from an established operator and are comfortable with Swiss jurisdiction.
Watch out for: Swiss (not EU) jurisdiction; self-serve onboarding.
Berlin-based, standards-respecting mail with an Open-Xchange office suite and video meetings, running exclusively in German data centres, with ISO 27001 and BSI C5 certifications already in hand, which is more than most of this list (including us) can say today.
It is mail-first: the business plans ship modest storage (10 GB mail + 5 GB drive on the €3 Standard tier), and the collaboration suite is functional rather than polished. For a small team that mostly needs trustworthy email, that can be exactly right.
Best for: Small teams and associations that want certified, affordable German email above all.
Watch out for: Small storage quotas; collaboration tools are the supporting act, not the headline.
The community answer: Euro-Office (generally available June 2026, backed by IONOS, Nextcloud, Open-Xchange and others) is an open-source web office that plugs into Nextcloud. Combined with Nextcloud Files and Talk plus a separate mail server, you can assemble a fully open-source, fully self-controlled workspace, yourself or through a hoster.
Note what it is: a stack, not a product. You (or your hoster) own integration, identity, mail, backups and the question of who is accountable when one layer breaks. For organisations with real IT capacity, that control is the point.
Best for: Organisations with in-house IT that want 100% open source and no per-seat licence.
Watch out for: You are the integrator, mail, meetings and identity are separate moving parts. · Detailed comparison →
The other Dutch entrant, launched from The Hague in March 2026 with the same pitch as ours: a fully European, open-source-based alternative to Microsoft 365 and Google Workspace. As of this writing it is in an invitation-only pilot, with general availability and pricing announced for later in 2026.
We are genuinely glad it exists: every credible European entrant makes switching less of a leap of faith. Until it opens its doors and publishes pricing, there is simply not much a buyer can verify yet, we will update this entry when that changes.
Best for: Keeping an eye on, worth re-checking once it exits early access.
Watch out for: Early access, invitation-only; pricing and feature set not yet public (as of July 2026). · Detailed comparison →
Prices are the providers' published entry rates as of July 2026 (Proton in USD, annual billing, Workspace Standard is the full suite while the cheaper Mail Essentials is mail and calendar only; mailbox.org Light tier, which sits on top of a service package from €25 / month; Infomaniak list prices, before their 50% first-year discount), check each provider for current figures.

On OVHcloud infrastructure in Paris, France, operated by a Dutch company (Remails B.V.) with an EU-only supplier chain down to payment processing. An EU region under an EU operator, not a US provider’s EU zone.
Our migration engine connects directly to Google Workspace and Microsoft 365, and also imports from any IMAP server or MBOX file. Mail, calendars and contacts move with you, hands-on with our team, and most cutovers complete over a weekend.
The product itself isn’t open source, but it’s assembled from proven open-source software we self-host in the EU: Stalwart for mail, Bulwark for webmail, ONLYOFFICE for documents, La Suite Docs for the wiki, La Suite Drive for files, La Suite Meet for meetings, Zulip for chat and Authentik for identity. Our orchestration layer is proprietary; the protocols and formats stay open, so you’re never locked in.
Yes. Everything stays reachable over open protocols, IMAP for mail, CalDAV and CardDAV for calendars and contacts, with full mailbox export to MBOX and no egress fees. Open formats throughout, so leaving is always possible.
Hand-onboarded by our team in Groningen. Migration tooling included, cancel anytime.
