Mailbox.org
Mailbox.org is a secure, ad-free German email hosting service with GDPR-compliant infrastructure in Berlin, offering email, calendar, contacts, cloud storage, and video conferencing from EUR1/month.
Our take
Mailbox.org is the strongest European alternative to Proton Mail for users who prioritize GDPR compliance, German data center infrastructure, and price. At EUR3/month for the Standard plan, you get email, calendar, contacts, 5 GB cloud storage, video conferencing, and collaborative document editing — a mini-Google Workspace equivalent at a fraction of the price, stored entirely in Berlin under strict German data protection law.
The positioning relative to Proton: Mailbox.org is not zero-access encrypted by default. Messages can be encrypted with PGP in the webmail interface, but the service has the technical ability to access stored email in a way Proton does not. The trade-off is practicality: Mailbox.org supports full IMAP/ActiveSync with any email client, has a usable webmail, and includes far more services in the base price.
What stands out
GDPR-compliant German infrastructure. Mailbox.org operates exclusively out of Berlin data centers subject to the strictest EU data protection framework. For European businesses and individuals with regulatory considerations, this is a meaningful legal guarantee.
EUR3/month Standard plan breadth. For three euros per month, you get email, cloud storage, video conferencing, and collaborative office tools. This is a compelling alternative to paying Google Workspace prices for a 1-5 person operation.
Anonymous sign-up. The Light plan does not require a name or physical address. Payment can be made anonymously. For users with strong privacy requirements, this is a rare feature from a legitimate commercial service.
Where it falls short
There are no native mobile apps — you use any IMAP or ActiveSync client on iOS and Android. The webmail (Open-Xchange) works but has dated UX compared to Gmail or Proton’s web interface. Light plan storage (2 GB) is tight.
Who should pick Mailbox.org
Pick Mailbox.org if you are a European user who needs GDPR-compliant email hosting, wants the full IMAP/CalDAV/CardDAV compatibility for any client, and values the German data center guarantee. It is especially strong for small EU businesses needing a privacy-respecting Google Workspace alternative at low cost.
