Retrieve a single email sending domain (DKIM/SPF/DMARC), including its ownership, transport, readiness, and return-path flags plus the DNS records to add at the provider. These are email sending domains - for website/hosting domains, see listDomains. verified reports transport only; ready_for_sending requires both workspace ownership and transport, while return-path verification is independent. Ownership is confirmed by connecting the domain, as www.example.com or another subdomain of it, to this workspace as a website/hosting domain in the ClickFunnels app, not through this API. dkim_record is null until the DKIM key finishes generating - re-POST the same name to createEmailsDomains to retry provisioning. This read returns the stored DNS verification state and never triggers a live DNS lookup (use verifyEmailsDomains to re-check), while ownership_verified is always current.
