Systems, methods, and computer-readable media for processing and sending messages with low latency are described. An application server may obtain a triggered send request (TSR) message from triggered send (TS) subscriber. The TSR message may comprise TSR information and a TSR payload. The application server may directly inject the TSR payload to an available message server for processing when the TSR information indicates that a first priority is associated with the payload, and may notify the available message server that the TSR payload is available for processing when the TSR information indicates that a second priority is associated with the payload. The application server may also write the TSR payload and/or TSR information to a TSS queue of a TSS tenant space, and may write the payload to a non-relational datastore regardless of a priority associated with the payload. Other embodiments may be described and/or claimed.
