    $email = $_POST["email"];
    $message = $_POST["message"];

    // Create email message
    $email_message = "Name: $fullname\n";
    $email_message .= "Email: $email\n";
    $email_message .= "Message:\n$message";

    // Set headers
    $headers = "From: $email";

    // Send email
    if (mail($to, $subject, $email_message, $headers)) {
        // Email sent successfully
        echo "success"; // You can customize this response if needed
    } else {
        // Email sending failed
        echo "error"; // You can customize this response if needed

} else {

}
