Yes you are! So if you have already sent that email campaign and you want to send it again to different contacts all you will need to do is go in to the Email Section and "Create an Email Campaign" 

Then once you are in Step 2: Pick a Template all you will need to do is Select "Past Emails Sent" 

This will then allow you to use an email campaign you have already sent and reuse (clone) it for a current campaign.
