List Engage queue
Read-only outbound queue across email, LinkedIn, and Slack (scheduled, sent, and approval-pending). This is where needsApproval sends live. Creating a draft does not add rows here. There is no MCP write/send tool; outbound send is REST-only. Grouped sends are normalized to a single row with recipient counts.
