To use Email Suite Pro, you need to download it from inside your JVZoo downloads portal and install it on your server. 

You can then set it up in your Covert Commissions account in the Profile>Autoresponder area.

The way it will work then, when connected - is that when a lead gets added into the Covert Commissions system, you can choose which list to add it to on your Email Suite Pro list - and you'll be able to mail from your Email Suite Pro account whenever you want.
