About Atomic Mail and Proton Mail
Explore the difference between two secure email providers
Atomic Mail is a privacy-first Proton Mail alternative built on a simple belief: real security and essential features should be accessible to everyone. End-to-end and zero-access encryption protect your inbox, while no-phone sign-up, aliases, and seed-phrase recovery help keep your identity private.
Proton Mail is a Swiss encrypted email service that helped popularize private email. While secure, its free plan comes with significant restrictions on storage, messages, and features. Its partial reliance on traditional recovery methods can also compromise the total anonymity many people expect from an email like Proton Mail.

Looking for a more private ProtonMail alternative? Choose Atomic Mail
Atomic Mail is a free email like ProtonMail focused on uncompromised privacy. Create an email account with zero personal data, use free aliases to separate identities, and rely on BIP39 seed-phrase recovery so only you can restore access – ideal for a truly private alternative to ProtonMail.
Proton Mail is secure, yet its anonymity depends on the setup. If account recovery is ever needed, traditional options like linking a phone number or additional email introduce a persistent data link that many users prefer to avoid.
Free email
Atomic Mail is the best free ProtonMail alternative
As a top Proton Mail alternative, Atomic Mail provides all core features for free. With unlimited storage, no daily message caps, and 10 free aliases included, it is built to feel complete from day one. The Plus plan only unlocks extra functionality for power users. This approach makes it one of the most capable free ProtonMail alternatives available.
Proton Mail offers a free tier that works as a basic starter. However, limits like 500 MB of storage (boostable only to 1 GB), a single email address, and a 150-message daily cap can become very problematic for many people. These restrictions often push users to upgrade or seek a more flexible email like ProtonMail.
Advanced email encryption
The best Proton Mail alternative must excel at encryption
Atomic Mail is built to make advanced security easy. You get TLS by default, plus multiple end-to-end encryption options: Atomic Encryption (ECIES) between Atomic accounts, and password-based or encrypted-ZIP delivery for any external recipient. No extra setup needed. All of it runs under zero-access design, so we can’t ever see your encrypted content.
Proton Mail is known for strong end-to-end encryption but can be complex for external communication. It uses PGP as a standard, which is secure but technically demanding. For users wanting quick, secure delivery to non-users, this friction often leads them to seek a more user-friendly ProtonMail alternative.
