If a customer replies to a message from the Telnyx API with a “stop word” message (e.g. STOP), Telnyx will automatically unsubscribe them from future sends.
If a SMS is too long for its destination, our API will automatically separate it into two messages. No more breaking out content into parts—we’ll handle that for you.
