A really important step is to add contacts to Watchtower so that they (and you) can get notified of issues with your website.
To do this, hover over the Watchtower tab on the WordPress admin sidebar and then click settings. Click Notifications if it’s not selected already. From this interface you can add contacts and enable notifications.
Go ahead and add yourself and anyone else who needs to be notified of downtime and other issues with your WordPress website.
