<p>The live preview loads your site's scripts and styles as long as they're enqueued via <a href="https://codex.wordpress.org/Plugin_API/Action_Reference/wp_enqueue_scripts" target="_blank">hooks</a>. If it looks wrong for you, make sure your scripts and styles are loaded correctly. You can test the validation and success messages but no emails will be sent.</p>
