I am new to Shopify as I migrated my store from Magento (best decision I ever made!) This app is great because it not only sends new customers the account creation invite (if they didn't create one when placing the order)...but now they created the option so you can have a link set up on the account set up page to notify past customers that they need to link their old account to this new one to preserve old order data! They have been very responsive and so helpful - a must-have! Thank you! PS - You can see how the account link is set up on the account page at our site InThisVeryRoom.com, and go to Sign In on top right of any page to see how the "Attention Users" notification information is there. Thank you!!!
We had an important launch. The app only sent to ¼ of our customers. Their support was responsive and helped us troubleshoot.
