Yes. Atomic Mail can receive emails from any email provider. However, it’s important to note that emails sent from other providers are stored on their servers before reaching Atomic Mail. These emails may not be encrypted during transmission or storage on the sender’s end, which could expose them to potential security risks.

Password-protected emails in Atomic Mail are self-destructing – they automatically become unreadable after 28 days. This ensures your sensitive messages don’t stay accessible indefinitely.

Atomic Mail currently offers unlimited email storage for free. You can store as many emails as you need without worrying about running out of space.

The maximum attachment size is 25MB per file, which is the standard limit in the email industry.

The attachment size limit is 25MB per file. However, if you need to send larger files securely, we recommend: splitting large files into smaller parts before attaching, compressing your files, or using an encrypted cloud storage service and sharing a secure download link via Atomic Mail.

If you can’t log in, first ensure that you’re entering the correct email and password. Double-check for typos and make sure Caps Lock is off. If you forgot your password, you can reset it using your recovery seed phrase. If the issue persists, contact our support team for assistance.

If you forget your password, the only way to recover your account is by using your recovery seed phrase. Go to the login page, enter your username and click "Forgot Password?". Due to our strict zero-access encryption, we do not store passwords, so without your seed phrase, account recovery is not possible.

If you’re not receiving emails, start by checking your Spam or Junk folder to ensure they weren’t filtered incorrectly. Verify that your device has a stable internet connection and confirm that no filters are applied (such as filters for starred messages, read messages, or messages with attachments). Double-check that the sender has used the correct email address to contact you. If everything seems fine but the emails are still missing, try logging out and back in to refresh your session. If the issue persists, don’t hesitate to contact our support team for further assistance.

If your email isn’t sending, first check that you have a stable internet connection. Confirm that the recipient’s email address is correct and that there are no typos. If the problem continues, try refreshing the page or using a different browser. For unresolved issues, contact our support team for troubleshooting.

If you receive a phishing or suspicious email, mark it as spam directly from your inbox (by tapping 👎 Junk) to help improve our spam filters. You can also forward the email to our security team for investigation, starting your message with something like "I've noticed a phishing attempt" for faster processing. To stay safe, avoid clicking on unknown links or downloading unexpected attachments.
