/**

 * @param string $subject email subject
 * @param \WC_Order $order the order object for the email
 * @return string updated subject

function skyverge_add_customer_to_email_subject( $subject, $order ) {

	$subject .= ' from ' . $order->get_billing_first_name() . ' ' . $order->get_billing_last_name();

	return $subject;
}
add_filter( 'woocommerce_email_subject_new_order', 'skyverge_add_customer_to_email_subject', 10, 2 );

hello, same question would be important for me. the code works fine, just the product name must be added to the subject.
How can that be done?
