        // SQL to remove the email from your mailing list
        $query = "DELETE FROM subscribers WHERE email = '$email'";

            header("Location: unsubscribe_success.html");
        } else {

        }
    } else {
        // Redirect to an error page if the email is invalid

    }
} else {
