Mailchimp syncs your customers, newsletter subscribers, products, and orders for email marketing campaigns run from Mailchimp.

Steps

Open Mailchimp from Apps and click Connect Mailchimp.
Enter your API Key and confirm the connection.
In the sync dialog, select which data types to sync (customers, newsletter subscribers, products, orders), then click Start Sync — or Skip for Now.
Track progress on the sync table: each data type shows Total, Completed, Failed, and Last Sync time, with a Resync action per row.
Under Settings → Event Tracking, enable Started Checkout and/or Placed Order so those actions are sent to Mailchimp for targeted campaigns.

A specific data type shows Failedopen that row's status details, fix the underlying issue (e.g. missing required customer field), then resync just that type instead of the whole store.
