I have a simple code, which should echo 1 if the mail is sent or 0 if it doesn't. But I am getting error 500. I tried changing the email, but it didn't work. Please suggest a fix.

                $subject = "Subject";
                $message = "This is a message";
                echo mail($to, $subject, $message);
