Any sysadmin can read your email, in general. There's no holistic "this email can't be read by anyone other than the recipient" as a solution, which is what a lot of us are aiming for. Things like protonmail and tutanota get really close, but they're proprietary solutions and don't work for "the many" (such as yourself) who use a hosted solution such as Gmail, who seem to have no interest in providing an open solution.
