关注this article后，如何添加自定义WooCommerce电子邮件，我们在发送电子邮件时遇到问题。
我们有自定义订单状态：
wp-call-unconfirmed
wp-call-confirmed
当任何订单从 wp-call-unconfirmed 更改为 wp-call-confirmed 时，想要向管理员发送电子邮件。
我们已为自定义电子邮件设置了一个插件，其结构如下：
/woocommerce-call-confirmed
/includes
- class-wc-call-confirmed-email.php
- woocommerce-call-confirmed-email.php
我们有一个更改订单状态的功能。我们调用钩子来触发电子邮件发送：
private function set_customer_call_verified( $order_id, $verified_status)
{
// Code ommitted, changes order status from unconfirmed->confirmed
// Is this the correct way to send our custom email?
do_action( 'woocommerce_order_status_call_unconfirmed_to_call_confirmed_notification' );
}
以下是我们的电子邮件文件：

require( 'includes/class-wc-call-confirmed-email.php' );

$email_classes['WC_Call_Confirmed_Email'] = new WC_Call_Confirmed_Email();
return $email_classes;
}
add_filter( 'woocommerce_email_classes', 'add_call_confirmed_woocommerce_email' );
但是，电子邮件不会发送。我已经在互联网上搜索了一种方法来做到这一点，并且无法找到它为什么不起作用。
我们是否遗漏了阻止电子邮件发送的内容？
