Immediately creates durable preparation for a broadcast draft or scheduled send. Mailrith calculates the exact Subscriber total and checks provider readiness in the background before delivery. A 202 response means the durable send was accepted, not that provider delivery is complete. Reuse the same idempotency key if the response is lost. Effect: external-email. Retry with the same idempotency_key. Permissions: live_actions:write, broadcasts:write. API reference: https://mailrith.com/developers/api-reference.
