Is Postmark down?
Operationalchecked 8 minutes ago
We reached Postmark from all 10 regions we check.
As of Oct 5, 2026, 8:07 PM UTC, Postmark answered RealUptime's probes in all 10 regions that returned a reading.
No outage recorded in the 44 days we have measured Postmark (since Aug 22, 2026).
Postmark publishes no status feed we can read, so the only independent reading here is ours on the left.
Postmark response time, by region
Is it Postmark, or is it you?
Watching an outage above does not tell you whether your own connection or site is also having a problem. Enter your own URL for one live check, right now, no signup. This checks the site you enter, not Postmark -- it cannot diagnose Postmark's own systems.
What we measured, function by function
Postmark answers on more than one surface, and they can fail apart. Each row is one surface, checked from the same regions. The verdict above follows the api row, because that is the surface we treat as this service's own; a failure on any other row is a partial outage, not a full one.

We will tell you when our probes stop reaching Postmark, and again when they can reach it again. That is our own measurement from ten regions, not Postmark's status page. No account, no card.

These are unverified reports from people using Postmark, counted separately from what our own probes measure. Anyone can file one, no account is needed, and the region on a report is chosen by the person filing it. We never open, extend or close an outage in our record based on report volume: only our own measurements do that. We have not received any reports for Postmark yet, which is not evidence that nothing is wrong.
Recent outages
No outages on record yet for Postmark.
measured entries are our own probes' readings; declared entries are the vendor's. How this check works
We have been measuring Postmark since August 22, 2026. We show nothing from before that date, and we never add an outage we did not observe ourselves, from any source.

Monitor your own site the same way
This page shows what we see when we check this service, using the same ten regions, for a site you run. RealUptime Monitor watches your own servers from inside your network, and it starts free.

If our readings go stale it says stale, and if we have no readings it says so: it will not show green on data we cannot vouch for. Free, no account, and it links back here.

What Postmark's SLA implies, from our measurement
At or above your target
We measured none of downtime for Postmark over the last 30 days, which is 100% uptime by our reading. A 99.9% target allows 43 minutes over that period.
By our measurement there is no shortfall to claim for this period.
This is computed from our own probe measurements, not from Postmark's SLA instrumentation. Their contract is normally measured against their own systems, with their own exclusions and a claim window, so their figure and ours will differ. Use this to start the conversation and ask for their number. It is not legal advice and it is not a determination of what you are owed.
