No custom sending domain is configured.
The required DNS records are missing or point somewhere incorrect.

The DNS records are correct but the tracking host is not yet serving traffic over HTTPS.
The DNS records are correct, but the tracking host has been temporarily unregistered because the newsletter has not sent recently. Sending again automatically re-verifies it.
