Can I send more than one SMS per request?

Yes!

You're able to send in batches of up to 100 SMS per HTTP POST using the RECIPIENTMESSAGES parameter and a JSON data array.

You can also safely send up to 3 simultaneous HTTP POSTs (via threading) to our API. This allows for a throughput of 300 SMS per second.

Note however that carriers have throughput limitations which may be less than the throughput we make available, so messages may queue on our side as we send to the carriers at their maximum allowed rate.
