What is Mailfence?
Mailfence is a privacy-focused email service developed in Belgium that provides end-to-end encrypted communication for individuals and businesses prioritizing digital security.

Frequently Asked Questions
Is Mailfence truly private?
Mailfence implements OpenPGP encryption where your private key never leaves your browser unencrypted. The company cannot read your encrypted emails. Operating under Belgian law, Mailfence can only comply with valid Belgian court orders and has published transparency reports documenting requests received.
Can I send encrypted emails to non-Mailfence users?
Yes, you can send encrypted emails to anyone using OpenPGP by importing their public key. For recipients without PGP, you can send password-protected messages that they access via a secure link, entering a password you share through another channel.
Does Mailfence support aliases?
Paid plans include email aliases allowing you to create additional addresses that forward to your main inbox. This helps organize incoming mail and protect your primary address from spam.
Can I use Mailfence with my own domain?
Yes, paid plans support custom domains. You configure DNS records to point your domain to Mailfence servers, allowing professional email addresses like you@yourdomain.com with full encryption capabilities.
What happens if I forget my encryption passphrase?
Your encryption passphrase protects your private key. If forgotten, previously encrypted emails cannot be recovered. Mailfence recommends securely storing your passphrase and keeping encrypted backups of your key pair.
Final Verdict
Mailfence delivers a comprehensive secure email solution that combines strong OpenPGP encryption with practical productivity tools. The inclusion of calendars, contacts, documents, and group collaboration features creates an integrated workspace that competitors like ProtonMail have only recently begun matching.

Operating from Belgium under strict EU privacy laws provides meaningful legal protection beyond what many competitors offer. While the interface may feel less polished than some alternatives, Mailfence compensates with functionality, competitive pricing, and a commitment to privacy that has remained consistent since the service launched. For users seeking secure email with genuine collaboration capabilities and standard protocol support, Mailfence represents an excellent value-focused choice in the encrypted email landscape.
