# Queue personalized messages

Queue up to 25 SMS, iMessage or email recipients through the shared send path. Each recipient may override body and subject and carry expected_last_message_id (latest reviewed message, 0 only for verified empty history). Results distinguish queued, skipped and rejected; succeeded means queued, not delivered. Duplicate destinations in one request are skipped. Never blindly replay partial or unknown outcomes. Sender selection uses the workspace service, not a caller-specified phone.

Access class: `workspace`.
