[SOLVED] Change "reply to" email address in all Woocommerce emails notifications

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

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?

Solution

Updates:

Added utf8_decode() to handle special characters (still works in WooCommerce 8.6.1)
Since WooCommerce 3.7, the WC_Email instance object is now included as the 4th argument in the function.

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, 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";
    $header .= 'Reply-to: ' . utf8_decode($reply_to_name) . ' <' . sanitize_email($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).
