Preventing blank schedule reports when data is not available

Requirement :

I need to send emails to the technicians at the end of everyday listing the number of tickets that are open and on hold for them ( if any ) till the current day.

My approach :

Create scheduled daily reports for all technicians with filters as

request status = open/onhold and

technician = technician name.

Now whenever their are no tickets open/onhold for that technician , a blank email will go to him.

How do i prevent this from happening?

I have seen other people posting on this forum regarding this issue , is there a way out to not emails when they have no open tickets ?

Please feel free to suggest any other method to meet my requirement , also let me know the possibility of the adding this feature in manage engine and by when it will be possible.
