Email addresses should only be used as contact info, not as a login name (and login names should also be different from your display/user name). Maybe I’m paranoid, but many sites will gladly tell anyone who knows your email that you at least have an account there. As the browser/password manager already fills in the password, why not just randomly generate the login name too? I currently use email aliases and burner email addressees on sites that don’t handle this well
