Mailfence
Private email from Belgium with built-in OpenPGP encryption

What is Mailfence?
Mailfence is an email service from Brussels-based ContactOffice Group that pairs a mailbox with a calendar, document storage and contact groups. Its OpenPGP encryption runs in the browser, with a keystore for creating and importing keys, and messages can also be protected with a shared password or signed digitally. A free plan offers 1 GB, and paid plans, billed in euros, add storage, aliases, custom domains and access from other mail apps.
Mailfence has a free plan. Paid plans start at €2.50 per month, billed yearly (Base). See every plan
Good for
- People who want OpenPGP encryption without installing a plug-in
- PGP users who want to import and manage their own keys
- Trying a private mailbox on a free plan before paying
Worth knowing
- The free plan stops at 1 GB, and free accounts are suspended after 7 months of inactivity and deleted 5 months later.
- Custom domains and POP, IMAP, SMTP and ActiveSync access start at the Entry plan; the Base plan has neither.
- End-to-end encryption is applied message by message: you choose which emails to encrypt.
- Mailfence bills in euros, the dollar figures its pricing table can show are a conversion, and subscriptions are not refunded.
Key features
- OpenPGP end-to-end encryption
- Messages are encrypted in the browser with OpenPGP, so they work with any other OpenPGP service and need no plug-in or add-on. You choose which emails to encrypt.
- Integrated keystore
- Generate, import, publish and export OpenPGP keys inside the account, including several key pairs, and take your keys with you if you move to another service.
- Password-encrypted messages
- A password agreed with the recipient encrypts the message, so people who do not use PGP keys can still read it through a link to Mailfence's servers.
- Digital signatures
- Emails can be signed digitally so the recipient can check that a message really came from you and was not altered on the way.
- Calendar, documents and groups
- The suite adds a calendar that can be shared, document storage with online editing and one-click sharing, and groups for sharing contacts and data.
- Aliases, domains and mail apps
- Paid plans include 10 to 200 aliases. Custom domains with DKIM, SPF and DMARC, and POP, IMAP, SMTP and ActiveSync access, start at the Entry plan.
