Helium Customer Fields

We came across this app after looking a so many others in the store. This is the only one that had full end to end customer registration form building as well as workflow and functionality to review and approve customer applications. By far the best app with great integration with Shopify. Well thought out and well built. We also could align emails from this app with our Shopify emails without any effort. Also had fantastic support in sorting out SPF/DKIM alignment issues with email.
