Send or schedule a campaign
Sends a draft now or schedules it for later.
MCP tool campaign_monitor_write → schedule_campaign
write Confirm
Does what Send now or Confirm schedule does. It reads the Assistant first and stops with its issues if the campaign cannot be sent. If the app asks for payment before a send to more than 5 recipients, the call returns payment_required and nothing is sent. By default you confirm each call; you can switch that off for this tool.
