You are configuring the SAP Emarsys Customer Engagement plug-in for Shopify. What is the first data set you should enable?
You have 1500 contacts and have manually uploaded 100 additional new contacts, but the number of available (opted-in) new contacts on the Database Growth widget still shows 1500 contacts.
You checked that the email address fields are filled and the email addresses are valid. What could be reasons why the additional new contacts are not showing?
