Emails not being delivered to a few specific domains

We've worked with our email provider to lift the domain blocks; emails to affected domains are being delivered again. Thank you for your patience!

We have identified that some emails are being blocked, but not due to any changes we have made. The changes seem to be due to changes to the infrastructure of our email provider. We are actively working with them to determine the scope of the impact, and how to resolve it as quickly as possible.

We are investigating a few reports of emails not being delivered to some domains. We are working to validate that and determine which domains are being affected. We will post back later once we have more details.
