Not able to send links in email after setting header

Nothing is wrong with the code.
I just added message body in stripslashes()

add_action('wp_ajax_mail_link_popup','mail_link_popup');
function mail_link_popup()
{
    $headers="Content-type: text/html;charset=utf-8";
    wp_mail($_REQUEST['to_email'],$_REQUEST['subject'],stripslashes($_REQUEST['message_test']),$headers);

}

And it’s working now
