Jinxcjinxc,
You could have Fusion watch your requests for the status change, when that occurs, you could do a create record for Note type which allows you to direct a message to a team or user (like the requester), essentially using the same process the update feed does so the user sees it within Workfront notifications. You could have a different note created based on the status if you needed to.
An example we do using this process (cause IT wouldn't allow us to tie into our email system) is when we create a user account. We have a custom form on the user profile with question that says Send a Training Plan? Yes or No. If Yes, it kicks off Fusion job to grab our training template and create a project for the user, we then post a note to the User account with the training plan link, which gives in-app notification but under global notifications there is an item to instant or email if user receives an update, so it also sends an email to user with the note and link (its a workaround).
