European alternatives to Gmail
Gmail is convenient, but analyzes usage data and processes data in the US. Anyone who wants more privacy will find several good email alternatives in Europe.
Why look for an alternative?
Common reasons include ad-free use, end-to-end encryption and European servers. For companies, the desire for a DPA and groupware features is added.
What to look for in an alternative
- Provider headquarters and servers in Europe
- Encryption or ad-free use
- Support for open standards (IMAP/SMTP/CalDAV)
- Groupware features for teams (calendar, contacts)
- DPA for business use

The top providers in detail
Proton offers an entire ecosystem around encrypted communication: Mail, Calendar, Drive, Pass (passwords) and VPN. Its headquarters in Switzerland, end-to-end encryption and own server hardware in Switzerland and Germany make Proton one of the best-known privacy alternatives to Google and Microsoft. All apps are open source; Proton is ISO/IEC 27001 certified and has a SOC 2 Type II report. Proton Mail Plus starts at €4.99 per month (€3.99 with annual billing), the Proton Unlimited bundle at €12.99 per month.
Strengths
- End-to-end encryption across the whole suite
- Own server hardware (Switzerland/Germany), no hyperscaler
- Open source, ISO 27001 and SOC 2 Type II
Weaknesses
- Headquartered in Switzerland (EFTA), not in the EU/EEA
- No self-hosting
- Encryption limits some convenience features
Tuta (formerly Tutanota) is a German email service with consistent end-to-end encryption for mailbox and calendar. According to the provider, the service is developed and operated 100% in Germany; the client code has been open source (GPLv3) since 2014. The focus is clearly on privacy, less on groupware features. Alongside a free plan, the cheapest paid plan (Revolutionary) starts at €3 per month.
Strengths
- End-to-end encrypted, headquarters and servers in Germany
- Open-source apps, ad-free
- Low-cost entry plans
Weaknesses
- No classic IMAP/SMTP access due to encryption
- Fewer groupware/business features
mailbox.org (Heinlein Group) offers ad-free email mailboxes with calendar, contacts, office and video conferencing based on the open-source OX App Suite (Open-Xchange). The servers are located exclusively in two redundant Berlin data centers; the service is ISO/IEC 27001 certified and attested according to BSI C5, and a TÜV-certified data protection officer monitors compliance. Unlike purely encrypted services, mailbox.org supports standard protocols (IMAP/SMTP/CalDAV) as well as PGP and S/MIME, making it a good Microsoft 365-like alternative. The Light plan starts at €1 per month, Standard at €3.
Strengths
- Standard protocols (IMAP/SMTP/CalDAV), PGP & S/MIME, groupware
- Servers exclusively in Germany, ISO 27001 + BSI C5
- Affordable from €1/month, ad-free
Weaknesses
- No continuous end-to-end encryption like Tuta/Proton
- Interface feels less modern
Migration effort

| mailbox.org | low | 80/100 |
| Posteo | low | 78/100 |
When switching pays off
For private users, Proton or Tuta are obvious choices; anyone who needs groupware and open standards is in good hands with mailbox.org.
When to stick with your current tool
If you depend heavily on Google Workspace integrations (Docs, Meet, Drive), plan the switch as a larger project and evaluate a combination of email and cloud alternatives.
