​What I thought I've seen previously is a form that allows a user to enter
their email address and have the system re-send them the original email as
if they had been originally included (without the other CC recipients but
that could be a nice touch). I had tried using digest mode for a while and
would have liked such a capability. For non-subscribers the flow would
need to be more considered.
