There are some reports that are best viewed in Workfornt and would benefit from "sending" the report but only sending a message to direct users to the link so they view the report in the system.
These reports are typically single reports that have broad usage across a very large user base. Case in point - reports that use the manager field as a filter to specifically show only users that report to that manager. This would allow creating one recurring report to send out instead of having to create a different recurrence of that for every unique manager.
