Removing customer details and addresses from email notification templates

Question

I am working on a theme created for woocommerce, built by some other German developer. I have created my child theme and using child theme's functions.php to make changes to functionality of the website.

When a customer orders a product, he receives an email with order table, customer information and billing address and customer shipping. I want to remove everything below the table and add my own text (customer info + billing, shipping and pick up address as well).

I have added my own text right below the order table in email that goes to customer, however I am unable to delete the information that shows by default below my custom added text. I found the hook responsible for fetching and showing that data is woocommerce_email_order_meta, but I don't know how to remove it or prevent it from executing. I don't want to make changes in the template files, I want to do it all by hooks.

So far I have tried doing it like this:

remove_action( 'woocommerce_email_order_meta', $order, $sent_to_admin, $plain_text, $email ); 

I followed the link: Delete order info section from email template in woocommerce and tried the following code as well, but didn't work.

function so_39251827_remove_order_details( $order, $sent_to_admin, $plain_text, $email ){
    $mailer = WC()->mailer(); // get the instance of the WC_Emails class
    remove_action( 'woocommerce_email_order_details', array( $mailer, 'order_details' ), 10, 4 );
}
add_action( 'woocommerce_email_order_details', 'so_39251827_remove_order_details', 5, 4 );

How can I achieve this?

Explanations - In all email notification templates you have this:

/**
 * @hooked WC_Emails::customer_details() Shows customer details
 * @hooked WC_Emails::email_address() Shows email address
 */
do_action( 'woocommerce_email_customer_details', $order, $sent_to_admin, $plain_text, $email );

After some research in WooCommerce core files and some test, I have removed successfully the customer details, the billing and shipping address from notification emails as you wished.

Here is the code:

add_action( 'woocommerce_email_customer_details', 'removing_customer_details_in_emails', 5, 4 );
function removing_customer_details_in_emails( $order, $sent_to_admin, $plain_text, $email ){
    $mailer = WC()->mailer();
    remove_action( 'woocommerce_email_customer_details', array( $mailer, 'customer_details' ), 10 );
    remove_action( 'woocommerce_email_customer_details', array( $mailer, 'email_addresses' ), 20 );
}

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

This code is tested and fully functional.
