Is Mailfence actually secure?

Yes—Mailfence offers genuine OpenPGP end-to-end encryption and is hosted in Belgium under EU privacy law. However, encryption is opt-in and manual, and stored mail isn't zero-access encrypted the way Proton's or Tuta's is.

What's the best Mailfence alternative for privacy?

Proton for Business and Tuta Mail are the top choices, both offering encryption by default and open-source clients. Mailbox.org and Posteo are strong EU-hosted options if you prefer PGP and standards.

Is there a cheaper alternative to Mailfence?

Yes. Zoho Mail starts around $1/user/mo and Posteo is a flat €1/month, both below Mailfence's paid tiers, though neither matches every Mailfence feature.

Can I keep using PGP if I switch from Mailfence?

Yes—Fastmail (via clients), Mailbox.org, Posteo, and Proton all support PGP workflows. Tuta is the exception: it uses proprietary encryption and doesn't interoperate with PGP.

Which alternative is best if I want a full office suite?

Google Workspace and Microsoft 365 offer the most complete collaboration and document tools; Proton for Business is the best pick if you want a suite that's also end-to-end encrypted.

Mailfence Alternatives (2026): 8 Additional Options for Secure Business Email

Mailfence is a Belgium-based secure email service that pairs OpenPGP end-to-end encryption with a calendar, contacts, documents, and group collaboration. It appeals to privacy-conscious professionals who want their mail hosted under EU (Belgian) jurisdiction and interoperable PGP rather than a proprietary scheme.

But its 3.3 Trustpilot rating hints at friction. The webmail and mobile apps feel dated next to modern clients, storage is modest on lower tiers, PGP key management is manual, and the collaboration tools don't compare to Google's or Microsoft's. Teams that outgrow a basic secure inbox—or want either a smoother experience or a fuller office suite—often start comparing alternatives.

TL;DR

For maximum privacy with a modern UX, Proton for Business and Tuta Mail are the strongest encrypted alternatives.
For a full productivity suite, Google Workspace or Microsoft 365 offer far more collaboration for a similar price.
Fastmail and Zoho Mail deliver fast, ad-free, standards-based email at a lower cost than Mailfence's paid tiers.
EU-hosted picks like Mailbox.org and Posteo match Mailfence's privacy stance with cleaner interfaces.

Why look for a Mailfence alternative?

The webmail and mobile apps feel dated and slower than modern clients like Gmail, Outlook, or Fastmail.
OpenPGP encryption is powerful but manual—key management and encrypting to non-PGP recipients is clunky for everyday use.
Storage and feature limits on lower-priced plans feel tight, and there's no free-tier custom domain.
Collaboration is thin: the document and group tools don't compare to Docs/Office or real team suites.
Support responsiveness and overall polish draw complaints, reflected in a middling Trustpilot score.

1. Proton for Business

Best for zero-access encrypted business email

★ 4.4· G2$7.99/mo

What it does better than Mailfence

Proton encrypts your mailbox with zero-access encryption by default, so even Proton can't read stored mail—stronger than Mailfence's opt-in OpenPGP. It bundles encrypted Calendar, Drive, Docs, Pass, and VPN into one Swiss-jurisdiction account, and the apps are far more polished. Audited, open-source clients add trust for regulated teams.

Where Mailfence still wins

Mailfence uses standard OpenPGP that interoperates with any PGP user, whereas Proton's encryption is easiest inside its own ecosystem. Mailfence is also cheaper at entry.

Best for: Privacy- and compliance-focused teams that want an entire encrypted suite, not just email.

2. Tuta Mail

Best for security-first teams on a budget

★ 4.6· G2$6/mo

What it does better than Mailfence

Tuta encrypts the entire mailbox—including subjects, contacts, and calendar—by default, and runs on fully open-source, green-hosted German infrastructure. Its apps are cleaner and faster than Mailfence's, and it includes an encrypted calendar with post-quantum encryption work ahead of most rivals.

Where Mailfence still wins

Tuta uses proprietary encryption with no IMAP/SMTP or PGP interoperability, so you can't use standard clients or exchange PGP with outsiders the way Mailfence allows.

Best for: Teams that want everything encrypted by default and don't need standard-protocol access.

3. Fastmail

Best for fast, standards-based email

★ 4.3· G2$3/mo

What it does better than Mailfence

Fastmail is dramatically faster and more polished, with excellent search, full IMAP/SMTP/JMAP support, and best-in-class calendar and contacts. Custom-domain setup is simple, and Masked Email (with 1Password/Bitwarden) protects privacy without PGP friction.

Where Mailfence still wins

Fastmail is not end-to-end encrypted, so for true message secrecy Mailfence's OpenPGP still has the edge. It's US-based (with data in the Netherlands), a different jurisdiction than Belgium.

Best for: Privacy-minded professionals who prioritize speed and standards over end-to-end encryption.

4. Zoho Mail

Best for value and small-business scaling

★ 4.5· Capterra$1/mo

What it does better than Mailfence

Zoho Mail is far cheaper (from about $1/user/mo), ad-free, and comes with a capable web app plus optional access to Zoho's huge business ecosystem. Admin controls, routing, and retention are more robust than Mailfence's for growing teams.

Where Mailfence still wins

Zoho isn't end-to-end encrypted, and its privacy jurisdiction and data-center model differ from Mailfence's Belgian hosting and PGP focus.

Best for: Startups and micro-businesses that want cheap, scalable email with room to add CRM and office apps.

5. Google Workspace

Best for browser-based collaboration

★ 4.7· Capterra$7/mo

What it does better than Mailfence

Google Workspace pairs Gmail with real-time Docs, Sheets, Meet, and Drive—collaboration Mailfence simply can't match. Search, spam filtering, mobile apps, and uptime are industry-leading, and admin tooling scales to any size.

Where Mailfence still wins

Google's model is ad-informed data processing rather than privacy-by-design, with no end-to-end encryption by default—the opposite of Mailfence's core pitch.

Best for: Teams that live in the browser and want the most productive, collaborative suite.

6. Microsoft 365

Best for Office-centric organizations

★ 4.6· Capterra$7/mo

What it does better than Mailfence

Microsoft 365 delivers Outlook plus the full desktop Office suite, Teams, and 1 TB of OneDrive—vastly more capability than Mailfence. Enterprise-grade compliance, retention, and identity controls suit larger or regulated organizations.

Where Mailfence still wins

It's heavier and more complex to administer, and like Google it isn't end-to-end encrypted by default, so it doesn't serve Mailfence's privacy-first niche.

Best for: Organizations standardized on Office apps and Windows identity.

7. Mailbox.org

Best for EU-hosted privacy with a cleaner UX

Standard plan around €3/user/mo; business plans from about €4/user/mo.

What it does better than Mailfence

Mailbox.org is a German privacy provider with PGP support (including Guard-based encryption of the whole mailbox), a cleaner interface than Mailfence, and an integrated office suite based on OX App Suite. It shares Mailfence's EU jurisdiction and standards-based approach while feeling more modern.

Where Mailfence still wins

Its brand and support are smaller-scale, and Mailfence's dedicated group and document tooling differ in scope.

Best for: Privacy-conscious users who want EU hosting, PGP, and a tidier all-in-one webmail.

8. Posteo

Best for bare-bones green privacy at €1

Flat €1/user/mo, no free tier; extra storage billed per GB.

What it does better than Mailfence

Posteo is a fiercely private German service that accepts anonymous payment, stores no personal data, runs on green energy, and supports full-mailbox encryption and PGP. At a flat €1/month it undercuts Mailfence while matching its privacy ethos.

Where Mailfence still wins

Posteo offers no custom domains and a much smaller feature set—no team or group tools—so it's less of a business suite than Mailfence.

Best for: Individuals and privacy purists who want cheap, green, standards-based email.
