Hi there,   We have a Shopify storefront, and we use Constant Contact for our email marketing. We are looking at migrating some data, and would like to see who in our user base would like to remain after the migration. We were thinking about using Constant Contact to send an email to our user base, and have them OPT IN or OPT OUT via a button click in the email. Depending on which button they click, that would tag their user account in Constant Contact. We were wondering if that information can be sent back to Shopify as well? So that when you view their user account on in the Shopify admin, you will see the tag there based on whichever button they clicked? I've been Googling, trying to find this answer, but to no specific avail. Any advice would be greatly appreciated!   Cheers ... View more
