}Add a domain
Registers a sending domain with the provider. Optional sendingPurpose is marketing (default; campaigns, audience sends, automations) or transactional (event-triggered automation mail — no unsubscribe link required, merely-unsubscribed contacts still receive it). Returns 201 with the bare row in status: "pending" plus the DNS records to publish. Once the records are live, call POST /v1/domains/{domainId}/verify until sendable: true.
