About mailbox.org
mailbox.org delivers secure German email bundled with Drive, Meet, and an office suite, positioning itself as a full productivity replacement for Gmail and Microsoft 365. The Berlin-based provider encrypts mail in transit and at rest, supports OpenPGP and S/MIME natively in its webmail, and offers a guard-tower UI that keeps keys, aliases, and filters within reach.
Behind the scenes, accounts integrate contacts, calendars, cloud storage with redundant backup, video conferencing, and collaborative document editing, all hosted on a single domain. Custom-domain support is available from the Standard tier upward, and a generous alias system (50 to 250 per mailbox) lets users compartmentalise identities without juggling accounts.
Key features:
- PGP and S/MIME built directly into the browser, with managed keyrings.
- Encrypted mailbox storage shields inboxes even from mailbox.org staff.
- Integrated Drive, Office, and Meet for a GDPR-safe productivity stack.
- Custom domains and 50-plus aliases included from the Standard plan.
- Spam and malware filtering tuned for German business compliance needs.
All data is stored exclusively in certified German datacenters, placing the service under GDPR, the German Federal Data Protection Act, and BSI C5 Type 1 oversight. mailbox.org holds ISO 27001 certification and publishes an annual transparency report detailing every government request.
Ideal for European SMBs, freelancers, and public-sector teams that want Microsoft-style collaboration without exporting their data to US clouds.
Why choose mailbox.org over Zoho Mail?
The decisive argument is data jurisdiction. Zoho Mail is headquartered in India, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
mailbox.org removes that overhead. As a Germany-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
