Following.
After setting up when I did a test order, did a few, then noticed all the test users show up on the list in mailchimp. Noticed the delay, testing now to find timing of delay.
Thanks for this info: This includes when a purchase made, when a shopping cart is abandoned, or when an order is manually updated from within WooCommerce’s admin panel.
Note to have email sent to customer, do not comment out ‘processing’ and just add line ‘completed’
$order->update_status( ‘processing’, __( ‘Payment to be made upon delivery.’, ‘woocommerce’ ) );
$order->update_status( ‘completed’, __( ‘Payment to be made upon delivery.’, ‘woocommerce’ ) );
