Unless communication is to spouse/partner, attorney, spiritual leader, then is there any expectation of privacy on the substance of the communication, even with use of encryption to open an email? I don't think so. So aside from practical difficulties with such an approach, I don't think it flies as a legal matter, either.There are laws against disclosing information decrypted from data received via encrypted radio transmission or public telephone network. (where the definition of "encrypted" is very, very broad). It has been argued that if the text was ever transmitted that way it is protected. Much of the internet and related communication is wireless, so it can be argued the prohibition applies even if the text was obtained another way. In that case there is an explicit legal framework.
While the cypertext of an encrypted email has no legal protection, the practical protection is that the person possessing it can't decode it. He can prove communication exists, but he can't prove its context. One might argue that people with enough resources, like a nation state, can always decrypt an email. Probably true if the cypher is a computer-based cypher with a key. However, most people and companies can easily distribute a one-time pad to those they communicate with which will defeat that threat, if they feel it necessary.
