A common option I see with many systems that have implemented Scheduled Reporting generally have an option for sending or not sending the email based on if the report returns rows or not. It is a must have for "Alert" style scheduled emails.
EG: If I select "No" for "Send if no results" for a daily email for payment methods created, No email would be sent out for that day if no new payment methods were created.
Currently it just always sends either an attachement or a link to the report with just the headers.
