+  - `template_id`, plus the same `draft` and participant `linked_person_id` / `linked_person_name` fields, in `GET /v1/deals/{id}/mailMessages`, `GET /v1/persons/{id}/mailMessages` and `GET /v1/organizations/{id}/mailMessages`
+  - `snippet_sent`, `last_message_received_timestamp`, `archived_flag`, `drafts_parties`, `parties.to[].linked_person_id` and `parties.to[].linked_person_name` (and the same for `parties.from`) in `GET /v1/mailbox/mailThreads`, `GET /v1/mailbox/mailThreads/{id}` and `PUT /v1/mailbox/mailThreads/{id}`
+  - `from[].linked_person_id` and `from[].linked_person_name` (and the same for `to`, `cc`, `bcc`) in `GET /v1/mailbox/mailThreads/{id}/mailMessages`
