Questions & Answers

What is an encrypted email?

It’s a message protected with cryptography so only the intended recipient can read it. A secure encrypted email shields content from providers, networks, and attackers, preserving confidentiality even if traffic is monitored or servers are probed.

What does an encrypted email look like?

Until it’s unlocked, it appears as scrambled ciphertext – meaningless characters to anyone who intercepts it. Once the intended recipient decrypts it with the correct key or password, the encrypted email displays normally in their inbox.

Is encrypted email secure?

Yes, especially with end-to-end encryption (E2EE). A robust encrypted email service plus zero-access policies ensures only sender and recipient can read the message, reducing exposure to data mining, breaches, and insider access at the encrypted email provider.

How do I send an encrypted email?

To send encrypted emails, choose a provider that supports robust end-to-end encryption, such as Atomic Mail. Write your message, choose encryption option (by a password, encrypt-as-file, or Atomic Encryption), then click ‘Send’. Our email encryption service handles the cryptography and key management automatically, so there is no need for manual setup.

How do I open an encrypted email?

It depends on the encryption method the sender chose. For password-protected or encrypted ZIP file messages, you'll simply need to enter a password. For messages sent with our Atomic Encryption, just open them in the Atomic Mail service to see them instantly.

Are there free encrypted email services?

Yes, but many limit essential features or use weaker encryption. We believe everyone deserves private communication, which is why our free encrypted email service includes all of our core security and encryption features without compromise.

What is the best encrypted email service?

The best encrypted email service offers advanced encryption, minimal data collection, anonymous sign-up, and a zero-ad experience. Atomic Mail was built on these principles, combining top-tier security with a simple, user-focused design.

Is it hard to use encrypted email?

No. With Atomic, encryption is a quick, per-message choice. You keep your normal workflow while our encrypted email service handles the complex parts, so secure communication feels as natural as sending a regular email.

Why switch to an encrypted email service from my current provider?

Most standard email providers treat you and your data as the product, scanning your messages for advertising and data collection. Switching to a secure encrypted email provider like Atomic Mail means you take back control. You get true privacy, protection from data mining, and superior security for your most sensitive communications.
