Credentials and external dependencies

DNS provider

Connected
Stored in your cluster
DNS records keep updating automatically even after you disconnect from the platform. Each zone's mode is set by credentials, not by a switch: a zone becomes automatic once DNS credentials for it are added and verified, and manual when they are revoked. Zone modes on the DNS page

External SMTP relay
