Static IP Deprecation: Third blackout period today, August 9th, from 4:00am - 4:00pm ET (12 hours)
The maintenance is now complete. Thanks for your patience.
The scheduled maintenance is now underway. We'll keep you updated on our progress.
Static IP Deprecation: Postmark will no longer support IP allow-listing for our API In the coming weeks, we’ll be making some changes to Postmark that will result in our API no longer being accessible on a static set of IPs. As such...
- IP allowlisting for our API will no longer be supported starting August 23, 2023.
- This change only applies to Postmark’s API and does not affect our SMTP and Webhook IPs.
We’ll retire support for static IPs on August 23, 2023 but we’ll be running a set of blackout periods before that to help you (and us!) catch any issues. Here’s what to expect:
August 9th: Third blackout period From 4.00am-4:00pm ET (12 hours)
