<h2><?php _e('WordPress Scheduler and Newsletter Delivery Engine', 'newsletter') ?></h2>
<p>
The scheduler is a WordPress component that executes <strong>background tasks</strong>
(publish future post, run backups, send newsletters, ...).
<br>
Here some steps you can consider if the scheduler has issues.
</p>
<ul>
<li>Check the <a href="<?php echo admin_url('/site-health.php') ?>">site health panel</a> and try to solve the issues identified by WordPress in your site</li>
<li>Install the <a href="https://wordpress.org/plugins/wp-crontrol/" target="_blank">WP Crontrol</a> plugin which shows all the scheduled jobs and delays</li>
<li>Configure an <a href="https://www.thenewsletterplugin.com/documentation/delivery-and-spam/newsletter-delivery-engine/" target="_blank">external cron service</a>
(if you have a license you can use our <a href="https://www.thenewsletterplugin.com/account/cron/" target="_blank">cron service</a>)</li>
