Your email address is the master key to your online life: password resets, bank alerts and your contacts all flow through it. Here are ten providers ranked for privacy, from fully encrypted services to the mainstream options most people use today.
End-to-end encryptionOpen-source appsSwitzerlandFree plan · Paid plans
The best-known encrypted email service, headquartered in Geneva. Messages between Proton users are end-to-end encrypted, and it integrates with Proton Pass aliases, Calendar and Drive. In 2025 Proton began moving some infrastructure outside Switzerland in response to a proposed Swiss surveillance law, while keeping its headquarters in Geneva.
Best for: Maximum encryption, including subject lines
Post-quantum encryptionOpen sourceGermanyFree plan · Paid plans
Formerly Tutanota, renamed Tuta in November 2023. Based in Hanover, Germany, it encrypts subject lines, attachments, calendars and contacts, and introduced post-quantum encryption (TutaCrypt) in 2024.
Strengths
Encrypts more than most rivals, including subject lines
Post-quantum encryption
Open-source apps
Weaknesses
No standard IMAP access for desktop clients
Free accounts are deleted after six months of inactivity
Best for: A private, full-featured Gmail replacement
PGP supportGermanyOffice suitePaid only
A long-running German provider with email, calendar, contacts, cloud storage and an office suite. Its built-in PGP option (Guard) encrypts on the server; for true end-to-end encryption, use a PGP browser extension such as Mailvelope. Works with standard email apps.
Strengths
Works with any email app (IMAP)
PGP encryption built in
Custom domains
Weaknesses
No free plan (30-day trial)
True end-to-end encryption needs your own PGP setup
A simple, ethical German provider that lets you sign up anonymously and pay in ways not linked to your account, including cash by mail, with an optionally encrypted address book and calendar.
From the team behind the Startpage search engine, based in the Netherlands, with one-click PGP encryption, tracking-pixel blocking and unlimited throwaway aliases.
A fast, ad-free provider with excellent apps, custom domains and masked email addresses. The company is based in Australia and stores mail mainly in the United States. It is private by business model but does not end-to-end encrypt your mail.
Excellent spam filtering and integration, but your email sits inside your Google account. Google stopped reading Gmail for ad personalization in 2017; mail is still not end-to-end encrypted.
Microsoft’s free email. Convenient with Windows and Office, but the free version shows ads in the inbox (a Microsoft 365 subscription removes them), and mail is not end-to-end encrypted by default.
Only you and your recipient can read the message, not the provider. Proton Mail and Tuta do this automatically between their own users; PGP does it between any two users who set it up.
Business model
Paid or freemium services that do not sell ads have less reason to analyse your mail.
Jurisdiction
The country where the company and its servers sit decides which laws can compel it to hand over data.
Aliases
Separate addresses for each site limit spam, tracking and the damage from data breaches.
Practical tips
Use a separate address, or aliases, for shopping and newsletters.
Turn on two-step login for your email first: it is the account that can reset all the others.
Remember that encrypted email still reveals metadata such as who you write to and when.
For sensitive conversations, Signal is often a better choice than email.
Proton Mail and Tuta, because they end-to-end encrypt mail between their users and do not rely on advertising. Tuta also encrypts subject lines.
Is Gmail private?
Gmail is secure against outsiders but not private from Google. Mail is stored in your Google account and is not end-to-end encrypted.
Can encrypted email be traced?
Yes, partly. Metadata such as the sender, recipient and time is usually visible to the providers involved.
Should I pay for email?
Paying funds the service directly rather than through advertising, and unlocks features like custom domains and aliases. Proton Mail, Tuta and Mailfence also have free plans.
