Does it matter much? From one side, you are still in the 14 eyes countries (in fact, I would trust a Chinese server if i am living in the west and vice versa), on another side, emails as a protocol was never meant to be secure or private, so deal with it as that, if you are after private or secure communication, choose a protocol that provides that, adding more stuff to emails will only complicate it further plus giving false sense of privacy/security, gpg will leak meta data, receiver email server/client might expose you too, among many gaps, so just avoid it. Still, make sure your email spf dkim dmarc etc are set properly and carry on.
