Identified - Due to a third party incident, starting around 3:14PM MT, users who are attempting to complete the Sender Authentication process on their account may be unable to complete the process and/or validate their domain. Also users who have previously completed domain authentication with “automatic security” enabled may notice SPF and DKIM no longer passing during this downtime. Our engineers are monitoring the situation and will provide updates as they become available. Please reach out to our Support team at with any questions.
