Long Table Distillery review for Mailchimp Email SMS Marketing

I am not sure how it will work as it's a bit of a mystery. I had an import issue for an "Age Verification" field that was a required merge and their support put me through rigours that did not resolve the issue. The age verification field was a mandatory field and there was no alternative to map it to in the pop up field entries. I just mapped it to Customer Notes so it would merge my date between Shopify and Mailchimp but who knows if that can be changed later or fixed so it records proof of age properly - we sell alcohol so this is important!! I wish I could call and talk with someone but no such option exists so I am still riding blind and wondering if it will work at all - confidence is low right now.
