Stop send specific email notification for specific users in Woocommerce

Question

I want to stop send Woocommerce email for specific user/email. this is my example code to stop send email when order is completed.

<?php
add_filter( 'woocommerce_email_headers', 'ieo_ignore_function', 10, 2);

function ieo_ignore_function($headers, $email_id, $order) {
    $list = 'admin@example.com,cs@example.com';
    $user_email = (method_exists( $order, 'get_billing_email' ))? $order->get_billing_email(): $order->billing_email;
    $email_class = wc()->mailer();
    if($email_id == 'customer_completed_order'){
        if(stripos($list, $user_email)!==false){
            remove_action( 'woocommerce_order_status_completed_notification', array( $email_class->emails['WC_Email_Customer_Completed_Order'], 'trigger' ) );
        }
    }
}

But WP keep send the email. I try to search in Woocommerce docs and source (github) and Stackoverflow also but still cant solve this.

In this example "Customer completed order" notification is disable for specific customer email addresses:

// Disable "Customer completed order" for specifics emails
add_filter( 'woocommerce_email_recipient_customer_completed_order', 'completed_email_recipient_customization', 10, 2 );
function completed_email_recipient_customization( $recipient, $order ) {
    // Disable "Customer completed order
    if( is_a('WC_Order', $order) && in_array($order->get_billing_email(), array('jack@mail.com','emma@mail.com') ) ){
        $recipient = '';
    }
    return $recipient;
}

Code goes in function.php file of your active child theme (active theme). Tested and works.

Note: A filter hook needs always to return the filtered main function argument

It can also be done from User IDs like:

// Disable "Customer completed order" for specifics User IDs
add_filter( 'woocommerce_email_recipient_customer_completed_order', 'completed_email_recipient_customization', 10, 2 );
function completed_email_recipient_customization( $recipient, $order ) {
    // Disable "Customer completed order
    if( is_a('WC_Order', $order) && in_array($order->get_customer_id(), array(25,87) ) ){
        $recipient = '';
    }
    return $recipient;
}

Code goes in function.php file of your active child theme (active theme). Tested and works.

i see you often answer WP question, you are really WP master my friend. — plonknimbuzz, Feb 28 '19 at 17:34
where i can find this parameter in docs? `woocommerce_email_recipient_customer_completed_order` — plonknimbuzz, Feb 28 '19 at 17:35
I have updated my answer … This hook is a composite hook: [`woocommerce_email_recipient_{$this->id}`](https://docs.woocommerce.com/wc-apidocs/source-class-WC_Email.html#351) … — LoicTheAztec, Feb 28 '19 at 17:42
excellent, i read that class before but didnt notice if that function can be used in my purpose. — plonknimbuzz, Feb 28 '19 at 17:49
@plonknimbuzz I have added an additional code that do the same from user Ids instead of emails — LoicTheAztec, Feb 28 '19 at 17:54

While answer above is working, this seems to be more straighforward solution:

add_filter( 'woocommerce_email_recipient_customer_completed_order', 'completed_email_recipient_customization', 10, 2 );
function completed_email_recipient_customization( $recipient, $order ) {
    if( in_array($recipient, ['some@email2block.com', 'another@email2block.com'] ) ) {
        $recipient = '';
    }
    return $recipient;
}
