How to monitor the status of Postmark and all your dependencies?

IsDown is a status page aggregator that monitors if Postmark and all your dependencies are experiencing issues. We combine the status of all the services you dependent and provide a clear view of all your vendors health in one place. We not only monitor official information but also crowdsourced reports. That means that even when Postmark, per example, doesn't report an outage, you will still be notified if other users are experiencing issues.

How IsDown monitors Postmark?

IsDown monitors Postmark health in almost real-time

Every few minutes we go to the status page of Postmark (and 5,350+ other services) and check if they are experiencing issues. We collect the status and outage information of Postmark's 4 components. Also, we not only monitor official sources but also user reports. Sometimes or a lot of times vendors take some time to report an incident, so by monitoring user reports we're able to alert you early.

The moment an issue is detected in Postmark, IsDown sends an alert and updates your status page

Not only you will get notified, but IsDown offers notification filters, so you can choose which issues you want to be notified about. This way you avoid getting all the incidents from Postmark and other services.

What you get when monitoring Postmark with IsDown

Track Postmark incidents and downtimes by severity

IsDown checks Postmark official status page for major/minor outages or downtimes. A major outage is when Postmark experiences a critical issue that severely affects one or more services/regions. A minor incident is when Postmark experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. The moment we detect a Postmark outage, we send you an alert and update your dashboard and status page.

Get alerted as soon as users reports problems with Postmark

Postmark and other vendors don't always report outages on time. IsDown collects user reports to provide early detection of outages. This way, even without an official status update, you can stay ahead of possible problems.

IsDown collects all information from the outages published in Postmark status page to provide the context of the outage.
