Woocommerice – wrong email sent (new order email sent on status completed)

These are the events that fire the email:

// Triggers for this email
		add_action( 'woocommerce_order_status_pending_to_processing_notification', array( $this, 'trigger' ) );
		add_action( 'woocommerce_order_status_pending_to_completed_notification', array( $this, 'trigger' ) );
		add_action( 'woocommerce_order_status_pending_to_on-hold_notification', array( $this, 'trigger' ) );
		add_action( 'woocommerce_order_status_failed_to_processing_notification', array( $this, 'trigger' ) );
		add_action( 'woocommerce_order_status_failed_to_completed_notification', array( $this, 'trigger' ) );
		add_action( 'woocommerce_order_status_failed_to_on-hold_notification', array( $this, 'trigger' ) );

If it was pending, and you make it complete, its considered new and is to be expected. Pending = unpaid.

Thanks for the quick reply and for the enlightenment!

A further question if I may: when would the completed email be sent?
I miss the technical knowledge I guess. Do I understand it right that I should change the status first from pending to something else before setting it to completed to get the completed email sent out?

Hope you can help me out just a bit more.

Completed is sent out when you change a pending or failed order to processing, completed or on hold.

Ok, maybe that is a language thing?
I read in your last reply that Completed is sent when I change pending (or failed) to completed (or to processing, or to on hold)?
But under 2. You say from pending to complete = new order email in stead of completed email? I get confused…

I would have thought Completed would mean something like all paid for & done or something like that. So that would be the kind of email sent when order marked as Completed.

If the order is PENDING, the admin has not been notified. So if you change it to something else it IS a new order.

thank you for your patience & advice
Have a great day!
