I have bought a domain from Google Domains. One of the features they offer is to redirect all email sent to that domain to any other email address of my choice. Now I'm wondering; is it secure and private?
How secure is using this service? Can Google read the content of the incoming emails if they redirect them for me?
Is it safer to let another site handle the email address(es) instead? For example, ProtonMail offer the possibility to receive all email sent to a domain I own. How does this option compare to telling Google to redirect the emails to my ProtonEmail account?
