In order to increase the stability and scalability of our core systems, our Midwest data center will undergo SCHEDULED MAINTENANCE Saturday, July 15th 5PM - 10PM MDT. During this time our website, as well as the Marketing Campaigns and Legacy Newsletter sites will be intermittently available. Our v3 API, Inbound Parse and Event Webhook services will also be intermittently impacted. Scheduled mail sends and campaigns will continue to be sent during the maintenance. Customers may also experience brief errors during upgrading, downgrading, or signing-up. If you experience this please try again after a few minutes.
Thank you for your patience through this maintenance. Please contact our support team with any questions: https://support.sendgrid.com/
