Using skin1/mail/html/order_data.tpl we added -
{if $order.coupon and $order.coupon_type eq "free_ship"}
<TR>
<TD align="right" height="20"><B>Coupon name:</B> </TD>
<TD align="right">{$order.coupon} </TD>
</TR>
{/if}
So if a customer uses one of coupon codes that gives them extra reward points, it is set up as Free Shipping in the admin, but on the order message that comes through iunder the subtotal it specifies the coupon code i.e.LT07116, which our inbound team pick up on and we act on accordingly.
Not perfect, but it works
