"Reply-to Address" Email

Question

I searched the web for last couple of days for "Reply-to Address" in the email but had no luck so, here I am.

In my wordpress site, there are multiple store owners who can sell their products. When visitors buy a certain item (listed by different owners), that particular owner gets an email notification (Note that it is mandatory to put the visitor's email address during checkout process)

However the email is from "Admin" email account.

I searched for how to set up "reply-to" address so the owners can reply directly to the customer's email address instead of admin account.

Here is an example that I saw which I am trying to achieve:

In this image, the site is abc.ca and the [email protected] bought something. Then the [email protected] got the email, which the owner can now send a reply back to the customer directly from the email.

How can I achieve something like this?

EDIT:

Here is the code that I have now:

 add_filter('woocommerce_email_headers', 'my_from_reply');
 function my_from_reply() {
 return 'From: [email protected]' . "\r\n";
 }

And this is the customer's billing email.

 <?php echo $order->billing_email; ?>

How can I modify the first one to include the "billing_email" instead of "[email protected]"

Thank you

If and when you are using wp_mail(), then you can just set Reply-To for the $headers parameter. Exemplary usage below:

$to          = "[email protected]";
$subject     = "Using Reply-To with wp_mail";
$message     = "This is an example for using Reply-To with wp_mail.";
$headers[]   = 'Reply-To: Name Name <[email protected]>';
$attachments = array();
wp_mail( $to, $subject, $message, $headers, $attachments ); 

There is a hook wp_mail hook too, which you could use to change the parameters.

In functions.php

// Function changes email that your site sending from
function change_my_from_address( $original_email_address ) {
    return '[email protected]';
}
add_filter( 'wp_mail_from', 'change_my_from_address' );

// Change sender name
function change_my_sender_name( $original_email_from ) {
    return 'example.pl';
}
add_filter( 'wp_mail_from_name', 'change_my_sender_name' );
