On Saturday, April 27, 2024, Postmark will be performing necessary maintenance starting at 11:00 PM US Eastern Time (3:00 AM UTC, April 28th). We expect the maintenance to last about 4 hours.

Here’s what you can expect during this maintenance window:

  • Our non-sending API endpoints and Postmark’s Web UI may be unavailable intermittently for up to 30 minutes.
  • While non-sending API endpoints are unavailable, we will be accepting mail via the API and SMTP.
  • Your messages will be queued for up to 30 minutes during our maintenance window, and they will get processed as soon as our engineers complete their work.
  • This applies to outbound messages sent via the API and SMTP as well as any inbound messages and bounce processing.
  • We will update you when the queueing starts and ends during the maintenance period.

Throughout the maintenance window, we will post updates here to keep you updated on the progress, including when exactly messages will be queued. Please get in touch if you have any questions. We're here to help!
