What should I do if Postmark is down for me?

Check whether delivery is delayed rather than failed, since messages are queued and usually arrive once a backlog clears. Test a second channel or recipient domain, because incidents are often limited to one carrier, region, or mailbox provider. Confirm you have not hit a rate or spend limit, which returns the same errors as an outage. Verify your webhook endpoint is still responding, as a receiving failure on your side mimics a provider problem.

Over the last 7 days, Postmark has answered our automated checks with 100.00% availability and a typical response time of ~70 ms. The most recent outage began 2026-10-04 09:05 UTC and lasted 19m (severity: degraded).

Postmark specialises in transactional email with an emphasis on deliverability and fast delivery times. Because its customers rely on messages arriving in seconds, even a modest processing delay is a real incident for password resets and one-time codes.

Is Postmark down for everyone or just you?

Our automated checks are reaching Postmark normally right now, and it answered our last one in 72ms. That makes any trouble you are hitting more likely to be local to your connection, account or network than a full outage, which usually means you can fix it from your end.
