Looking forward to starting to use this plugin with an existing store, but realized that it’s important to first know if existing contact data and subscription status are ever overwritten in Mailchimp when customer data from the website syncs to Mailchimp.

Are any fields (name, etc.) overwritten when customers sync from website to Mailchimp via this plugin?

Is the subscription status of customers ever overwritten when syncing from website to Mailchimp? What if a subscribed customer unsubscribes–would syncing from this plugin ever re-subscribe them?

What about the initial sync, with the “auto-subscribe existing customers” checked or unchecked in the plugin? Could that ever change the subscription status of existing contacts in Mailchimp?

For instance, would an existing contact who is unsubscribed in Mailchimp be subscribed, if the “auto-subscribe existing customers” box is checked?

Conversely, would an existing contact who is subscribed in Mailchimp be unsubscribed during the initial sync, if the contact also exists as a customer via the WooCommerce plugin and the “auto-subscribed existing customers” box is not checked?

Looking forward to hearing back–thanks!
