I recently used the Quickbooks GoPayment system to run customer credit card transactions for my business at a tradeshow. When customers paid for their items, they entered their email addresses after swiping their cards. I would like to store those email addresses to send updates etc. to the customers but I am not able to find them. The customers are expecting emails from me containing info about their orders etc. so without these addresses, it's like I've lost all contact info for the customer. Is there a way to access email addresses that are collected by GoPayment?
