For Common Rule email Notification defined in Client - Help with spacing

In the M-files Client, we've defined some Common Rule email Notifications.  I've been working on modifications to Email Templates for each notification in the Admin under Configurations \ Advanced Vault Settings \ Notifications \ Notification Templates \ Email Templates.  But I'd like to alter how the multiple documents appear in the digest email notification.  Each one seems to take up a lot of vertical space with a divider line.

Here's what the email looks like; 

I'd like to have just one contract listed each on it's own line without the blank line or dividing line between them.

To the Template Section for this notification, I did add the "Digest: Message Separator" with a Template Entry value of <DIV> <HR> </DIV>  and that didn't seem to help.

Anyone have any suggestions for how to modify the spacing between each of the lines in the email?
