It's email. Any pretense of avoiding 5/9 eyes is already moot. Any conversation has at least 2 participants, and since 50+ percent of the world population runs on some kind of hosted email (Gmail/Outlook/Yahoo/whatever), anything you send has a high probability of passing through 5/9 eyes anyway. It doesn't make much of a difference if you look through the "from:" or "to:" headers. The only way to be safe from 5 eyes is encrypting all the contents in your mailbox, either through GnuPG or using Protonmail/Tutanota.
