Our progressive web app loads in under 1 second on 3G and feels native on desktop. Dark mode, keyboard shortcuts, and offline reading included.
Bring your own domain with one-click DNS wizard. Auto-configures SPF, DKIM, and DMARC. Unlimited email addresses under your domain, even on Personal plan.
Use Mailhost with Thunderbird, Apple Mail, Outlook, or any standard client. Bridge app available for seamless encrypted IMAP access without any configuration complexity.
Native apps with biometric unlock, push notifications, and background sync. Available on App Store and Google Play — open source on F-Droid too.
ML-powered filtering trained on billions of messages. Custom rules, blocklists, and sender verification. Average false positive rate under 0.002%.
Fully encrypted CalDAV calendar and CardDAV contact book, synced across all devices. Import from Google, Apple, or Outlook with one click.
Powerful server-side rules, nested folders, color-coded labels, and AI-assisted categorization that runs fully on-device — so your classification patterns are never sent to any server. Plus one-click unsubscribe for marketing emails and automatic newsletter sorting.
No installation, no complex setup, no DNS knowledge required for the basic account.
Pick a username at mailhost.vip or connect your own domain. Availability check is instant and usernames are yours forever — we don't reclaim inactive accounts.
Your encryption key pair is generated directly in your browser. The private key never leaves your device. Recovery phrase is shown once — save it securely.
Emails to other Mailhost users are automatically E2E encrypted. PGP keys for external contacts can be fetched from public key servers or pasted manually.
Download the mobile app or install the Desktop Bridge for IMAP access. One password protects all — or use hardware security keys for maximum security.
We've designed Mailhost so that even we — the people who run the servers — cannot access your email. Here's how.
Your public/private key pair is generated in-browser using the Web Crypto API. Your private key is encrypted with your password and stored locally. Our servers only store your encrypted public key and ciphertext.
We apply SRP (Secure Remote Password) authentication so your password is never transmitted in plain text — not even hashed. We cannot reset your password; only you can decrypt your mailbox.
All cryptographic code, mobile apps, and the web client are published on GitHub. Annual security audits by Cure53 and SEC Consult. Full audit reports published publicly.
Mailhost Ltd. is incorporated in Iceland — outside the EU but with GDPR equivalent laws and no mandatory data retention. We have never received a valid court order for user content.
Our business model is subscriptions — not surveillance. We have never served ads, never shared user data with advertisers, and never will. This is enshrined in our corporate charter.
All servers are in ISO 27001 certified data centers with biometric access controls. Hardware security modules (HSMs) manage any infrastructure-level key operations. Full disk encryption on all storage media.

"I switched from ProtonMail after years. Mailhost has the same privacy guarantees but with IMAP support that actually works, a nicer interface, and a free plan that isn't embarrassingly limited. The migration tool imported 40,000 emails flawlessly."
"As a lawyer, client confidentiality is paramount. Mailhost is the only provider I found that gives me E2E encryption, a custom domain on my firm's name, AND works with Outlook via IMAP. The HIPAA/GDPR documentation was also exceptional."
"Mailhost's Business plan replaced three separate tools for my 20-person team: Gmail, a newsletter service, and a calendar app. The shared inbox feature is brilliant — and everything is actually encrypted, unlike most 'private' email providers."
"The web app is genuinely the fastest encrypted email client I've used — even faster than regular Gmail for me. Dark mode is well-implemented and keyboard shortcuts cover every action I need. Minus one star only because Android app is still in beta."
"Migrated our entire journalism team of 35 people from Google Workspace. Mailhost's admin console is surprisingly polished for a smaller provider. Source protection matters enormously in our work, and zero-knowledge gives us real peace of mind."
"The $3.99/mo Personal plan is genuinely unbeatable. Custom domain, 50GB, IMAP, and real encryption for less than a coffee. I recommended it to my entire family. Setup was painless even for non-technical members — the DNS wizard is clever."
