Your personal e-mail account, your personal computer, your personal network (I wonder what that thing is?) and your email application are absolutely irrelevant. If your computer is connected to any public computer network for some time and no matter how long and where (but in real life it always is), then everything else has absolutely no importance - all your actions are traceable, but not readable. And you can be absolutely sure that your boss can follow your every move, but he will never be able to read your emails, because they are encrypted and encrypted so that you and no one else know, because all email servers use very complex systems related to your password and user ID and much more.
If you want, here is a small example of my own encrypted text.
If you open it, let us all know what it says, what there is written.

I will wait for the right answer. What is the content of this letter?
