+<h3>Crontab</h3>
+
+<p>
+When using cron, probably the easiest is to append a <code>curl</code>
+or <code>wget</code> call after your command. The scheduled time comes,
+and your command runs. After it completes, the healthchecks.io check
+gets pinged.
+</p>

+<p>With this simple modification, you monitor several failure
+scenarios:</p>

+<ul>
+    <li>The whole machine has stopped working (power outage, janitor stumbles on wires, VPS provider problems, etc.) </li>
+    <li>cron daemon is not running, or has invalid configuration</li>
+    <li>cron does start your task, but the task exits with non-zero exit code</li>
+</ul>
+

+<p>Both <code>curl</code> and <code>wget</code> examples accomplish the same

+    If using <code>curl</code>, make sure it is installed on your target system.

+
+<h3>Email</h3>
+<p>
+    As an alternative to HTTP/HTTPS requests,
+    you can "ping" this check by sending an
+    email message to <a href="mailto:{{ check.email }}">{{ check.email }}</a>
+</p>
+<p>
+    This is useful for end-to-end testing weekly email delivery.
+</p>
+<p>
+    An example scenario: you have a cron job which runs weekly and
+    sends weekly email reports to a list of e-mail addresses. You have already
+    set up a check to get alerted when your cron job fails to run.
+    But what you ultimately want to check is your emails <em>get sent and
+    get delivered</em>.
+</p>
+<p>
+    The solution: set up another check, and add its
+    @hchk.io address to your list of recipient email addresses. Set its
+    Period to 1 week. As long as your weekly email script runs correctly,
+    the check will be regularly pinged and will stay up.
+</p>
+
+
+<h2>When Alerts Are Sent</h2>
 <p>
     Each check has a configurable <strong>Period</strong> parameter, with the default value of one day.
     For periodic tasks, this is the expected time gap between two runs.
