These are Quiq’s outbound messaging best practices. Please review them carefully before sending a large number of outbound messages.


SMS is regulated by the Telephone Consumer Protection Act (TCPA) and CAN-SPAM act. Please do not initiate an SMS conversation with your clients unless you have received explicit opt-in for their phone number.

This does not apply when a client initiates an SMS conversation by texting your company first.

SMS Rate Limits

Regular phone numbers have an average rate limit of one message per second. This rate limit is enforced by the SMS carriers and is outside of Quiq’s control. Short codes have a higher rate limit but are expensive.

If you plan to consistently send more than one message per second, you must contact Quiq. We will need to allocate multiple numbers to handle this load. If you consistently send more than this on a single number then Quiq’s internal buffers will fill, you will start receiving error codes from the API, and your messages will not be sent. This could also affect your normal inbound SMS traffic if you are using the same number for inbound and outbound.

Sending Outbound Messages

Quiq has two ways to send outbound messages: Quiq user interface and the Quiq programmatic interface (API).

User Interface

Your users can initiate conversations with customers using our user interface. When the customer responds, a new conversation will be created in the Quiq user interface. Our user interface allows you to send one message or bulk send to multiple end users.

Programmatic Interface (API)

Quiq exposes an API to send SMS messages and initiate conversations with your clients. Quiq customers will often use this API to bulk send notifications to their customers. One example is shipping notifications, but there are many other uses. Again, be sure you have obtained your customers’ permission before texting them. If a customer responds to the notification, a new conversation will be created in Quiq.
