About Postmark Status and Outage Monitoring
IsDown has monitored Postmark continuously since March 2022, tracking this Email Delivery for 4 years. Over that time, we've documented 159 outages and incidents, averaging 3.5 per month.
We monitor Postmark's official status page across 4 components. IsDown interprets Postmark statuses (operational and incident) to deliver precise health metrics and filter alerts by the components you actually use.
To check if Postmark is down, IsDown combines official status data with user reports for early detection. Vendors often delay acknowledging problems, so user reports help us alert you before the official announcement.
Engineering and operations teams rely on IsDown to track Postmark status and receive verified outage alerts through Slack, Teams, PagerDuty, or 20+ other integrations.
How IsDown Monitors Postmark
IsDown checks Postmark's status page every few minutes, across all 4 components. We combine official status data with user reports to detect when Postmark is down, often before the vendor announces it.
When Postmark status changes, IsDown sends alerts to your preferred channels. Filter by severity to skip noise and focus on outages that affect your business.
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 report 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.
All the details of Postmark outages and downtimes
IsDown collects all information from the outages published in Postmark status page to provide the context of the outage. If available, we gather the title, description, time of the outage, status, and outage updates. Another important piece of information is the affected services/regions which we use to filter the notifications that impact your business.
