Of course, you could make sure that when the admin clicks the Update button, the input sends the command to the email of the subscriber.
But I’m not a programmer of your plugin.

Yes, I had thought this. But the simplest way is that when I publish an updated post, a notice immediately begins for the registered user.
Can you change this to your plugin?

RESOLVED, Is default’s theme.

I saw that you issued a new version, you forgot to correct this layout

Ok, maybe I didn’t explain myself: I need a code that the user clicks and cancels his registration.
Eg: “If you want to cancel your subscription click here: {code}”

Ok. I put this in functions.php file child, then what I do?

function bitly_keyword( $string, $token = 'PUT YOUR API TOKEN HERE') {
    global $mysubscribe2;
    $link = $mysubscribe2->get_tracking_link( $mysubscribe2->permalink );
    $bitlydata = wp_remote_get('https://api-ssl.bitly.com/v3/shorten?access_token=' . $token . '&longUrl=' . urlencode($link));
    $data = json_decode( wp_remote_retrieve_body( $bitlydata ) );
    if  ( 'ok' === strtolower($data->status_txt) && 200 === (int)$data->status_code ) {
        $bitlylink = '<a>data->url . '">' . $data->data->url . '</a>';
    } else {
        $bitlylink = '<a href="' . $link . '">' . $link . '</a>';
    }
    return str_replace('{BITLYLINK}', $bitlylink, $string);
}
add_filter('s2_custom_keywords', 'bitly_keyword');
