# Send Message

{{variable.AudienceAdmin}}

Send messages to callers over text channels, such as SMS and WhatsApp.

## Introduction
Use the **Send Message** node to send a text message to a caller. Send a message to deflect callers from IVR to text channels.

:::(Internal) (Private notes)
 or to handle times when queue wait times exceed a certain threshold
:::

:::(Warning) (Important)
The call continues to the next node regardless of the outcome of the message execution (sent, not sent, delivered, not delivered, or error).
:::

When the message is sent, an interaction is logged to the [CDR](/v1/docs/reporting-cdr).

### Connections
The **Send Message** node allows unlimited input connections and 1 output connection.

## Using the Send Message node
