I guess if you want any privacy you should use the USPS.
Email is not a secure medium, and trying to pretend that it is is foolish.
Passing laws to restrict the ability of third parties from reading email makes as much sense as passing laws to keep the rest of the neighborhood from listening in while you the guy next door yell at each other from your respective back porches.
Email is a party line that anyone can listen in on. If you don’t want everyone to hear, encrypt it.
can this be used to find out what the EPA is up to ?
