    On February 3, 2026 between 10:08 and 10:26AM PT, our engineering team investigated a service disruption that impacted Marketing Campaigns creating Single Sends, Automations, Contact uploads, and API configuration requests. Customers would have experienced 500 errors. Mail send was not impacted and Legacy Marketing Campaigns were not impacted. Our engineering teams have identified the root cause and restored full functionality. No mail was lost. Services are now operational. We apologize for any inconvenience.
