New version code : Add a new order status that Send an email notification in WooCommerce 4+

---

To make it work for a new custom order status (here "Awaiting delivery") you should need:

• to register the custom new order status first,
• to display it in bulk edit dropdown on admin orders list (optional) ,
• to display it in order edit pages status dropdown
• to send an customized email notification when an order get this custom status.

The code:

// register a custom post status 'awaiting-delivery' for Orders
add_action( 'init', 'register_custom_post_status', 20 );
function register_custom_post_status() {
    register_post_status( 'wc-awaiting-delivery', array(
        'label'                     => _x( 'Awaiting delivery', 'Order status', 'woocommerce' ),
        'public'                    => true,
        'exclude_from_search'       => false,
        'show_in_admin_all_list'    => true,
        'show_in_admin_status_list' => true,
        'label_count'               => _n_noop( 'Awaiting delivery <span class="count">(%s)</span>', 'Awaiting delivery <span class="count">(%s)</span>', 'woocommerce' )
    ) );
}

// Adding custom status 'awaiting-delivery' to order edit pages dropdown
add_filter( 'wc_order_statuses', 'custom_wc_order_statuses', 20, 1 );
function custom_wc_order_statuses( $order_statuses ) {
    $order_statuses['wc-awaiting-delivery'] = _x( 'Awaiting delivery', 'Order status', 'woocommerce' );
    return $order_statuses;
}

// Adding custom status 'awaiting-delivery' to admin order list bulk dropdown
add_filter( 'bulk_actions-edit-shop_order', 'custom_dropdown_bulk_actions_shop_order', 20, 1 );
function custom_dropdown_bulk_actions_shop_order( $actions ) {
    $actions['mark_awaiting-delivery'] = __( 'Mark Awaiting delivery', 'woocommerce' );
    return $actions;
}

// Adding action for 'awaiting-delivery'
add_filter( 'woocommerce_email_actions', 'custom_email_actions', 20, 1 );
function custom_email_actions( $action ) {
    $actions[] = 'woocommerce_order_status_wc-awaiting-delivery';
    return $actions;
}

add_action( 'woocommerce_order_status_wc-awaiting-delivery', array( WC(), 'send_transactional_email' ), 10, 1 );

// Sending an email notification when order get 'awaiting-delivery' status
add_action('woocommerce_order_status_awaiting-delivery', 'backorder_status_custom_notification', 20, 2);
function backorder_status_custom_notification( $order_id, $order ) {
    // HERE below your settings
    $heading   = __('Your Awaiting delivery order','woocommerce');
    $subject   = '[{site_title}] Awaiting delivery order ({order_number}) - {order_date}';

    // Getting all WC_emails objects
    $mailer = WC()->mailer()->get_emails();

    // Customizing Heading and subject In the WC_email processing Order object
    $mailer['WC_Email_Customer_Processing_Order']->heading = $heading;
    $mailer['WC_Email_Customer_Processing_Order']->subject = $subject;

    // Sending the customized email
    $mailer['WC_Email_Customer_Processing_Order']->trigger( $order_id );
}

Code goes in function.php file of your active child theme (or active theme).

Tested and works (should work on any Woocommerce versions above 2.5)

In others function if you use the WC_Order method update_status() to change an order to 'awaiting-delivery' status like:

 $order->update_status();

the related email notification will be sent too.
