When defining the action flow of your action, you can send the same SMS to a group of users. Instead of building the logic to send to each user, you can use the Send Bulk Messages element which you can drag onto your canvas from the Action Flow Toolbox. The message is built in a specific editor, just by dragging & dropping the available elements.
This element has the advantage of optimizing the send message since it is only one SMS send to n destinations. With the Send Bulk Messages element the message is send asynchronously to the destinations you specify.
You can add the following elements to your Send Bulk messages element:
Input parameters: Used to send data to the Send Bulk Messages element;
Local variables: Used when you have to create variables the scope of which is the Send Bulk Messages itself;
Screen actions: Used when you want to design actions that are only available inside the Send Bulk Messages.
Send Bulk Messages is available in the following situations:
Message Queues Component is installed in your server. If this component is not installed, a warning message is presented and you should contact your Service Center administrator.
