Bolt Fabric Boutique review for Mailchimp Email SMS Marketing

We have experienced the same horrific issue of repeat customers getting booted from our email list if they do not continually opt in with each transaction, and if we don't continually opt in for them when checking them out via the Shopify POS. This is such a costly "glitch." I see your response and that Shopify is supposedly looking into this. But, this response has been posted for months. Is there really no fix yet from Shopify?
