Glew’s Email Marketing analysis, under the Performance tab, combines data from both your email platform and your ecommerce cart. If you use Mailchimp and Shopify, you may notice some metrics missing after May 2019, including revenue and orders. This is because we pull those metrics from Mailchimp – when Mailchimp and Shopify ended their partnership, those metrics were no longer automatically available.
In order to view revenue and orders for Mailchimp campaigns, you will need to have your revenue and order data imported from Shopify back into Mailchimp You can do this manually, or using a third-party app like ShopSync or Zapier.
From Mailchimp: “Once the integration (Shopify) is phased out, historical data will remain available in Mailchimp for up to 30 days. After that point, purchase data, and some customer information, will no longer be visible in Mailchimp. Your Shopify data will remain available through your Shopify account, and you can choose to import it back into your Mailchimp account.”
