Are emails sent from ProtonMail to Tutanota (or vice versa) ever not encrypted?


1. ProtonMail and Tutanota are both end-to-end encrypted email services.
2. Emails sent between the two services should be fully encrypted, but there are some possible scenarios where this may not be the case.


1. Introduction to ProtonMail and Tutanota
a. Both services offer end-to-end encryption for all emails.
b. They are popular choices for people who value privacy and security.
2. How email encryption works between ProtonMail and Tutanota
a. Emails sent between the two services are encrypted on the sender’s device, and can only be decrypted by the recipient’s device using their private key.
b. This means that even if an attacker intercepted the email in transit, they would not be able to read its contents.
3. Possible scenarios where encryption may fail
a. If either the sender or recipient is using an outdated version of the app, there could be compatibility issues that prevent encryption from working properly.
b. If one of the parties has disabled encryption in their settings, the email will not be encrypted.
c. In some cases, emails may be forwarded to non-encrypted email addresses, which would render the encryption useless.
4. Mitigating these risks
a. Both ProtonMail and Tutanota encourage users to keep their apps up-to-date to ensure compatibility with each other’s services.
b. Users should also be aware of their own encryption settings and make sure they are always enabled.
c. If forwarding emails, users should be mindful of the security of the destination address, and consider using a separate encrypted service if necessary.


a. While emails sent between ProtonMail and Tutanota should generally be fully encrypted, there are some potential scenarios where this may not be the case.
b. By staying up-to-date with their apps, being aware of their own encryption settings, and being mindful of where they forward emails, users can minimize the risk of compromising their privacy and security.
