# Opt-Out nodes

The *Opt-Out* action nodes allow you to add opt-out functionality to your workflows. There are three nodes that you can use:

* Opt-Out node
* Verify Opt-Out node
* Delete Opt-Out node

This functionality can be used for the SMS channel, WhatsApp channel, or both.

**Opt-Out node**

This node facilitates the ability to opt a number out of receiving unwanted communications.

The available parameters for this node are:

* The name of the flow.
* A description of the flow.
* The ability to add Opt-Out numbers.&#x20;
  * You can add more than one number. These numbers will be added to the Opt-Out list and will not receive any messages on the selected channel.
* The channel that has been opted out from.
