Mailfence

Mailfence is a privacy-first email and collaboration suite. It was launched in response to increasing global concerns about email surveillance and data privacy.

Designed as a European alternative to Big Tech email platforms, Mailfence gives users end-to-end encryption, full data sovereignty, and robust tools — all hosted in Belgium under strict European privacy laws (GDPR).

It is ideal for individuals, professionals, journalists, NGOs, businesses, and anyone seeking secure digital communications.

Key features & strengths:

• End-to-end encrypted email — using OpenPGP standards

• Full interoperability — can send encrypted mail to users of any PGP-compatible service

• Secure calendar, contacts, and document storage

• No ads, no tracking, no third-party analytics

• Hosted entirely in Belgium — inside EU legislation

• Strong transparency — regular transparency reports published

• Support for custom domains and business accounts

• IMAP, SMTP, POP3, and mobile apps — full flexibility for usage

Unlike many privacy-oriented email services that rely on closed ecosystems, Mailfence offers interoperability — meaning users can communicate securely with anyone using standard OpenPGP encryption.
