What is required to ensure a client receives an email notification regarding a new request for information?

To ensure a client receives an email notification regarding a new request for information, it is crucial to set the Notify client slider to On. This action explicitly activates the notification feature within the system, which triggers an automated email to be sent to the client, informing them about the new request.

The other options may not guarantee that the client receives the notification. Making the request urgent might change its priority but does not necessarily trigger an automatic email notification. Adding a note requesting they check their email does not initiate any specific action within the system and relies on the client to remember to check their email, which is not effective for ensuring timely communication. Including their email address in the message is important for correct delivery but does not activate any notification system in itself. Setting the Notify client slider to On is the definitive step to establish the automatic email communication needed in this scenario.
