ShopSync can keep your customer tags in sync with your Mailchimp Audience. Getting started with tags is easy. Just add the tags you want to send over to Mailchimp from the ShopSync settings panel, and you’re good to go. We’ll send the tags over for orders that come through after you set up the configuration.
If you have tags that you want to map from Shopify to Mailchimp, add them in the app settings of ShopSync
