WooCommerce：仅为一封电子邮件触发电子邮件

Question

是否可以只为一个收件人触发来自 Woo 的已完成电子邮件？ 谢谢！

add_action( 'woocommerce_order_status_partial-shipped', 'partial_shipped_trigger_on_custom_email_notification', 20, 2 );
function partial_shipped_trigger_on_custom_email_notification( $order_id, $order ) {
 
    // Get WooCommerce email objects
     $recipient = 'test@gmail.com';
     $mailer = WC()->mailer()->get_emails();

    // $wc_emails = WC()->mailer();
    $mailer['WC_Email_Customer_Completed_Order']->recipient = $recipient;
    $mailer['WC_Email_Customer_Completed_Order']->settings['recipient'] = $recipient;

    // Send the email with custom heading & subject
    $mailer['WC_Email_Customer_Completed_Order']->trigger( $order_id );
  
}
