Go ahead and edit the email template as you need to, by directly modifying the template text file.
Control Panel > Templates > Choose Template: email_html.tpl
or
It is located/named:
/templates/default/email_html.tpl
You'd probably edit the {if $posts}{/if} group. But that would also affect people forwarding posts and mailing private posts (PM/PT) to each other. It also effect when someone reports a post. Basically, it affects any type of post that goes through email.
