Mailfence is a Belgian email service that pitches itself as a privacy-respecting alternative to the likes of Gmail and Proton Mail. I spent some time testing it firsthand, and here’s what you need to know before signing up.

Mailfence markets itself as a secure, privacy-first email platform — and it mostly lives up to that claim.

Who Is Mailfence For?

If you’re based in Europe and care about where your data is stored and processed, Mailfence is worth a serious look. It’s headquartered in Belgium, which means it operates under EU law and is fully GDPR-compliant. On top of that, it runs entirely on 100% green energy — a small but meaningful detail for environmentally conscious users. For those exploring the best European email alternatives to Gmail, Mailfence regularly comes up as a credible option.

Mailfence is both GDPR-compliant and powered entirely by renewable energy — two boxes that matter for European users.

Creating an Account: Simple, With One Catch

The registration process is refreshingly minimal. You choose your @mailfence.com address, set a password, and confirm you meet the minimum age of 16 — a requirement tied to GDPR compliance. It’s clean and quick.

The sign-up form is lean and GDPR-conscious — you must confirm you’re at least 16 before creating your account.

There is one thing to watch out for, though. Mailfence requires a recovery email address not just for password resets, but to actually activate your account in the first place. If you try to use a disposable or blacklisted email domain here, registration will fail immediately.

A valid recovery email is required to activate your account — skip the disposable addresses here.

I ran into exactly that issue during my own sign-up. Mailfence actively filters out throwaway email domains, and it can also temporarily block registrations from certain IP addresses or regions. It’s not a dealbreaker, but it’s worth knowing upfront. If you hit a wall, waiting 24 hours usually helps — or you can reach out to their support team directly. In my case, support stepped in and created the account manually, so the process isn’t entirely self-serve if things go sideways.

The Interface: Functional, Not Flashy

Once you’re logged in, the interface is organized and perfectly usable — but it won’t win any design awards. It has that unmistakable feel of early-2010s webmail. If you’re coming from Gmail or Proton Mail, the visual step-down is noticeable. Think Outlook circa 2014. That said, everything works as expected, and the layout is logical enough that you don’t have to hunt for things.

The inbox is functional and well-organized, with folder and tag support in the left sidebar — though it feels more utilitarian than polished.

Composing messages is straightforward. The compose window keeps things simple with basic formatting tools and attachment support — nothing overly complicated.

What makes Mailfence stand out from a plain email provider is everything that comes bundled alongside the inbox. There’s a built-in calendar, a contacts manager, and a cloud document storage section. The document storage is particularly handy — you can upload and organize files, and even mount it as a virtual drive directly from your computer. It’s a privacy-focused productivity suite in one package rather than just an email service.

Encryption: Flexible but Manual

This is the area where Mailfence takes a noticeably different approach from competitors like Proton Mail and Tuta (formerly Tutanota). Both of those services encrypt your inbox automatically, with zero-knowledge encryption applied by default — you don’t have to think about it. Mailfence works differently.

Mailfence supports both OpenPGP end-to-end encryption and password-based encryption, but they’re opt-in features. You choose to encrypt a specific message at the time of composing it. Standard emails sent to recipients outside Mailfence travel as regular email unless you actively apply encryption. For users who want always-on, automatic privacy without any configuration, this distinction matters.

Mailfence encryption options when sending
When composing, you can choose between password-based or OpenPGP encryption — powerful, but requires deliberate action.

That said, the encryption tools themselves are genuinely strong. OpenPGP support means you can send encrypted messages to anyone using PGP-compatible software — not just other Mailfence users. You can generate and manage keys, digitally sign your messages, and verify who sent something. This is actually a significant advantage over Tuta, which relies on a proprietary encryption format that only works within its own ecosystem. Mailfence’s approach is more open and interoperable by design.

Pricing: Reasonable and Transparent

Mailfence offers a free plan that gives you enough access to properly evaluate whether the service suits you. Paid plans unlock features like email filtering rules, additional storage, and access via desktop email clients using IMAP, POP, and SMTP. Pricing is clear and competitive — in some respects more affordable than Proton Mail’s paid tiers. There’s no sense that you’re being pushed into an expensive plan just to get basic functionality. You can visit Mailfence’s website to compare the current plan options.

One Notable Gap: No Scheduled Sending

One feature that’s conspicuously absent is scheduled sending — the ability to write an email and have it delivered at a specific time. Proton Mail supports this; Mailfence doesn’t, at least not yet. For casual users, it’s a non-issue. But for professionals or power users who rely on this kind of tool regularly, it’s a real gap in an otherwise fairly complete feature set.

How It Stacks Up: Pros and Cons

✅ Pros ❌ Cons
Belgian jurisdiction, fully GDPR-compliant Interface feels dated compared to modern alternatives
OpenPGP and password-based encryption support Encryption is opt-in, not applied automatically
Interoperable with any PGP-compatible software No “Send Later” / scheduled sending feature
Includes calendar, documents, and contacts Free tier comes with limited storage
Fair, transparent pricing Registration can fail with certain email domains or IPs
100% green energy powered

Final Verdict

Mailfence is a solid and trustworthy privacy-focused email service. It’s particularly well-suited to European users who want their data protected under EU law, and to anyone who values open encryption standards over a walled-garden approach. The combination of OpenPGP support, GDPR compliance, and a built-in suite of productivity tools — calendar, documents, contacts — makes it more than just another inbox. It’s a genuine privacy-respecting alternative to Big Tech email at a fair price point.

It does have real weaknesses, though. The interface looks like it hasn’t been refreshed in a decade. Unlike Proton Mail or Tuta, there’s no automatic zero-knowledge encryption applied to everything by default — you have to opt in each time. And the missing scheduled send feature is a small but persistent frustration. If zero-effort, always-on encryption is your top priority, Proton or Tuta may be a better fit for your workflow.

But if what you’re after is open standards, flexible OpenPGP encryption, European hosting, and a complete productivity suite at a reasonable price, Mailfence is absolutely worth your consideration.
