Now, to make all things work, you should edit the mail.php file and specify your email address in the $mail_to variable.

<?php
*
* Author: Shadow Themes
* Author URL: https://shadow-themes.com


if ($_SERVER["REQUEST_METHOD"] == "POST") {

    # Replace this email with your email address
    $mail_to = "yourmail@example.com";
    
    ...
}
?>
