blacklist

Manage domain and email blacklists.

An entry suppresses sending only within the scope it was created in — the organization, or a specific workspace/clientspace when the call carried arguments.workspaceId/clientspaceId. It does not propagate to the parent organization or to other sub-orgs, in either direction: neither the list view nor the blacklist/*_check enforcement endpoint sees an entry created in a different scope. Suppressing in the scope you are operating in is the right default; add entries in other scopes only when the user explicitly wants account-wide suppression — to suppress an address everywhere, add it in each scope that needs it.
