Create a sending subdomain

client.emailSending.subdomains.create(, ?): SubdomainCreateResponse { enabled, name, tag, 6 more }

POST/zones/{zone_id}/email/sending/subdomains

Creates a new sending subdomain or re-enables sending on an existing subdomain that had it disabled. If zone-level Email Sending has not been enabled yet, the zone flag is automatically set when the entitlement is present. A leftmost wildcard such as *.example.com is accepted only for accounts with wildcard Email Sending enabled. Wildcard senders share the base domain’s DKIM signing identity and cf-bounce.<base> return path.
