详细信息
The preflight the "set up email" screen reads: whether the governing plan includes mailboxes, how large each one is, and how many a domain may have. Reports rather than refuses — an organization with no plan gets included: false and an upgrade prompt, not an error, because this is a read screen. Resolution walks up the parent_org chain, so a reseller's client organization inherits the reseller's plan (CLAUDE.md §2.3). source names where the answer came from. mailbox_limit is the smaller of the plan's mailboxes grant and the platform abuse ceiling, so it does vary by plan; -1 means both are uncapped. Requires mail.view. ⭐ Pass fqdn whenever the question is about one domain, which is nearly always. Since the owner's ruling of 2026-08-16 a domain registered with us — or transferred in — grants free mailboxes on itself, whatever the organization's hosting plan says, and that grant is only reachable when the hostname is supplied. Without fqdn this endpoint answers the narrower question "does anything the organization owns include mail at all", and a customer whose only product is a domain gets included: false followed by a successful mailbox creation — a screen disagreeing with its own API.
