I couldn't find where to customize the email title. I would like to add the user that generated the event. Ex: in a comment notification, the user that made it. I need that to create smart filters in gmail, in order to know which reviews had been handled and require me (as a reviewer) to review the corrections and close (or reopen). Mentioning that, I don't think the upsource workflow is clear - using the web app, how to know which review comments were handled by the authors?
