UPDATE 2 (Change from woocommerce_new_order to woocommerce_checkout_order_processed thanks to Céline Garel)

This code will be fired in all possible cases when a new order get a pending status and will trigger automatically a "New Order" email notification:

// New order notification only for "Pending" Order status
add_action( 'woocommerce_checkout_order_processed', 'pending_new_order_notification', 20, 1 );
function pending_new_order_notification( $order_id ) {

    // Get an instance of the WC_Order object
    $order = wc_get_order( $order_id );

    // Only for "pending" order status
    if( ! $order->has_status( 'pending' ) ) return;

    // Send "New Email" notification (to admin)
    WC()->mailer()->get_emails()['WC_Email_New_Order']->trigger( $order_id );
}

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

This code is tested and works in WooCommerce versions 2.6.x and 3+.

A more customizable version of the code (if needed), that will make pending Orders more visible:

// New order notification only for "Pending" Order status
add_action( 'woocommerce_checkout_order_processed', 'pending_new_order_notification', 20, 1 );
function pending_new_order_notification( $order_id ) {
    // Get an instance of the WC_Order object
    $order = wc_get_order( $order_id );

    // Only for "pending" order status
    if( ! $order->has_status( 'pending' ) ) return;

    // Get an instance of the WC_Email_New_Order object
    $wc_email = WC()->mailer()->get_emails()['WC_Email_New_Order'];

    ## -- Customizing Heading, subject (and optionally add recipients)  -- ##
    // Change Subject
    $wc_email->settings['subject'] = __('{site_title} - New customer Pending order ({order_number}) - {order_date}');
    // Change Heading
    $wc_email->settings['heading'] = __('New customer Pending Order'); 
    // $wc_email->settings['recipient'] .= ',name@email.com'; // Add email recipients (coma separated)

    // Send "New Email" notification (to admin)
    $wc_email->trigger( $order_id );
}

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

This code is tested and works in WooCommerce versions 2.6.x and 3+.

In this version you can customize the email heading, subject, add recipients...

Answer 2

I've tried with LoicTheAztec answer, @LoicTheAztec thanks a lot for your great code.

I have just changed the action hook from woocommerce_new_order to woocommerce_checkout_order_processed to get it to work.

Here is the action : add_action( 'woocommerce_checkout_order_processed', 'pending_new_order_notification', 20, 1 );

Hope that helps.
