Except its completely unencrypted
So is regular mail. Should we stop sending physical letters?
If itβs that important, write your email in code.
I mean, your connection to your email provider is encrypted (I hope!) - probably with TLS
Your email provider will communicate with the receivers email server over an encrypted connection (probably TLS again)
Your recipient connects to their provider over a secure connection too!
Yes, your email companies can read it, but that is the case with lots of IM providers tooβ¦
More widespread adoption of WKD (https://wiki.gnupg.org/WKDHosting) would be fantastic.
Yeah, itβs not without faults, so ProtonMail and similar may be a good compromise, or encrypting and sending longer documents. Ideally one day email will be rebuilt from the ground up with encryption.
Also to address your later comments, E2EE messengers are great, but short form writing is simply a different use case from long form.
