Swismail – Free Email Supporting PGP and E2E Encryption

There is not much information about Swissmail , the registration process is very simple, just enter your name, email ID and password, no other additional information is required. The mailbox size is 1GB, and the number of sent and forwarded emails per day is limited to 2000, which is more than enough for ordinary people.

Email Features

  • Support PGP encryption and end-to-end encryption
  • Support two-step verification
  • Support IMAP, POP3, SMTP
  • Aliases are supported. I don’t know the limit on the number of aliases. I have added 5 at present. The ID length includes a single letter, double letter, three-letter, and four-letter. I haven’t tried numbers. Except for some common words are reserved, others can be added successfully.

Email Registration

I won’t say much about email registration, the registration process is very simple. Open the official website and click “SIGN UP” in the upper right corner or click https://swismail.com/account/create .

Refer to the IMAP, POP3 and SMTP information in “Setting” and use the application-specific password generated by “Security” -> “Application specific passwords” to replace the mailbox password.


  • It seems that there is no address book function.
  • This GPG encryption is a bit fascinating. What is displayed in the Swissmail outbox is that GPG encrypted emails cannot be viewed, but the recipients receive ordinary emails, which do not need to be decrypted with GPG keys.
