You would have to tie the h1 and @missing lines together, so that the
@missing group is only obeyed if the h1 group would have won in the cascade.
Note that this example is degenerate in that the only selector in the
@missing block is h1, but that would have to be enforced, if one was to
avoid other selectors being introduced that were incompatible with a
subsequent, or !important, h1 rule that changed the background image to
one that did exist.

Emails are not formal business letters, whatever businesses may want.
RFC1855 says there should be an address here, but, in a world of spam,
that is no longer good advice, as archive address hiding may not work.
