Additionally, the encryption protocols used in Tutanota enable us to easily upgrade to new algorithms and add support for Prefect Forward Secrecy. Tutanota encrypts not just bodies and attachments of emails, but also the subject line, which can contain very sensitive information.

ProtonMail uses PGP encryption, which lacks important requirements that Tutanota is able to fix. In addition, there are quite important differences in the encryption methods used. One major differentiation here is that in Tutanota external recipients can access the entire email thread via the shared password while recipients of encrypted messages from Proton Mail are limited to just seeing one message. It’s worth noting here that ProtonMail is actively targeting businesses as well, so being able to mass export / import emails will be a big selling point beyond the consumer realm.Both Proton Mail and Tutanota offer end-to-end encryption for all emails, and both enable users to use a password for encrypting emails sent to recipients that don’t have an address with an encrypted email provider. And many may have avoided jumping ship from Gmail simply due to the hassle of starting anew elsewhere. Even if someone is already using ProtonMail, they will likely have at least one other legacy email account that they keep for various reasons. However, one of the inherent hurdles for users in terms of switching email providers is that they may have a decade or more worth of messages in other accounts leaving all that behind is a big decision, and one, ultimately, that many will decide against.Īllowing people to import their emails from other services represents a notable evolution for ProtonMail, as it removes a big barrier for full adoption. The company claims it has garnered more than 5 million users since launch a few years ago. Such stories underpin ProtonMail’s core selling point: “Your emails are safe with us” is the general idea.
