Change registration notice recipient

WooCommerce B2B, among its features, allow you to send email to admin on every new customer account registration, so when a customer create an account, an email is send to admin to inform him.
But in some cases, you may want the recipient of this notification be another email address instead of the administrator.

To do this, edit functions.php file that you find in your site’s FTP space in:

 wp-content/themes/{YOUR_ACTIVE_THEME}/functions.php

and insert this code:

add_filter( 'wp_new_user_notification_email_admin', function( $wp_new_user_notification_email_admin, $user, $blogname ) {
    $wp_new_user_notification_email_admin['to'] = 'example@domain.com';
    return $wp_new_user_notification_email_admin;
}, 10, 3 );

If you need, you can specify multiple recipients using an array or comma-separated list of email addresses to send message:

add_filter( 'wp_new_user_notification_email_admin', function( $wp_new_user_notification_email_admin, $user, $blogname ) {
    $wp_new_user_notification_email_admin['to'] = 'example@domain.com,example1@domain.com';
    return $wp_new_user_notification_email_admin;
}, 10, 3 );
