On Friday, February 17, 2023, Postmark will be performing necessary database maintenance starting at 8:00 pm Central Time. We expect the maintenance to last about 2 hours.

Emails sent from your website might get queued for a short period of time 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.

You can get up-to-date info about this event on Postmark's website:
