The Send Autoresponse filter is designed to send an agent notification based on a matching expression within a filter. This differs from other autoresponses that are sent based upon the topic configuration.
The setup requires three steps.
1 - Create the autoresponse that will be sent to the agent.
2 - Create the filter using an expression to match and two actions: Select Agents and Send Autoresponse.
3 - Apply the filter to a mailbox (usually via groups) or a topic for Ask a Question submissions.
