Hey Andre,<br><br>This can be easily done by a custom module, just some simple queries and code, and it will be done.<br>You can select the active users from the database by referring to status field in users table (1 is active, 0 is blocked), and email them whatever content you want to.<br>

Also, if in case you want to send a drupal defined mail, these are stored in variables table, so you can refer that as well.<br><br><div class="gmail_quote">On Wed, May 4, 2011 at 8:55 AM, Andre Durudas <span dir="ltr">&lt;<a href="mailto:durudasa@gmail.com">durudasa@gmail.com</a>&gt;</span> wrote:<br>

    The Rules module looks good for a variety of reasons. However, I
    don&#39;t think it&#39;ll work for my purposes. I need something to send an
    email to all registered active users on a manual trigger. With
    Rules, it seems, I can only define automatic triggers.<br>

        Hello,<br>
        <br>
        is there an easy way to email all registered active users on a
        Drupal 7 site? Any module for example? I could not find
        anything...<br>
        <br>
        Thanks,<br>
        Andre<br>
