Change "reply to" email address in all Woocommerce emails notifications

Question

In Woocommerce, I would like to change the email address that should always be used as the reply address for all emails notifications.

How is this possible with Woocommerce?

Answer 1

The following will change the "Reply to" email address (and name) in all email notifications:

add_filter( 'woocommerce_email_headers', 'change_reply_to_email_address', 10, 3 );
function change_reply_to_email_address( $header, $email_id, $order ) {

    // HERE below set the name and the email address
    $reply_to_name  = 'Jack Smith';
    $reply_to_email = 'jack.smith@doamin.tld';

    // Get the WC_Email instance Object
    $email = new WC_Email($email_id);

    $header  = "Content-Type: " . $email->get_content_type() . "\r\n";
    $header .= 'Reply-to: ' . $reply_to_name . ' <' . $reply_to_email . ">\r\n";

    return $header;
}

This code goes on function.php file of your active child theme (or theme). Tested and works (Thanks to helgatheviking).

Note (update): Since WooCommerce 3.7, the WC_Email instance Object is now included in the hook as 4th argument.

add_filter( 'woocommerce_email_headers', 'change_reply_to_email_address', 10, 4 );

function change_reply_to_email_address( $header, $email_id, $order, $email ) {
    
      // HERE below set the name and the email address
      $reply_to_name  = 'Jack Smith';
      $reply_to_email = 'jack.smith@doamin.tld';
    
      $header  = "Content-Type: " . $email->get_content_type() . "\r\n";
      $header .= 'Reply-to: ' . $reply_to_name . ' <' . $reply_to_email . ">\r\n";
    
      return $header;
}
