Send an email when Execute SQL Task stops, but doesn't error.

Hello,

I'm trying to put together an SSIS package that will look in one directory for 2 distinctly named .csv files.  The files will then be loaded into 2 tables. 

The first task I execute is a SQL Task that checks to see if the tables I'm loading the data into are empty.  If the tables have data, the package stops executing.  If they are empty, the package continues to execute.

What is the best way to send an email out from SSIS if the package stops on the first step? 

Thanks!
