Email Preview to Free Members

Hi
Thanks for this amazing software. God Bless.
I was wondering if there is a feature to turn on the email snippet (like adding a separator of public preview).

Basically email will be sent to everyone - paid members will get full email in their mailbox vs free members will only get the section that is available to public (above the fold of public preview).

This will be useful for attracting more free users to eventual paid users.
