<h1>Email</h1>
|
|
<p>As an alternative to HTTP/HTTPS requests, you can "ping" checks by
|
|
sending email messages to special email addresses.</p>

<h2>Use Case: Newsletter Delivery Monitoring</h2>
|
|
<p>Consider a cron job that runs weekly and sends weekly newsletters
|
|
to a list of email 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 if
|
|
<strong>your emails are getting sent and delivered</strong>.</p>
|
|
<p>The solution: set up another check, and add its email address to your list of
|
|
recipient email addresses. Set its Period to 1 week. As long as your weekly email
|
|
script runs correctly, and there are no email delivery issues,
|
|
SITE_NAME will regularly receive an email, and the check will stay up.</p>
