Transact SQL :: Only Generate Email If Table Contains Data?

I am wanting to fire-off an email with the failed jobs anytime they are deposited into a table.  My syntax fires off an email even when the table does not contain data, it just sends a blank email.  this will only generate an email if teh table contains data?  

if exists (Select from FailedJobs)
exec msdb.dbo.sp_send_dbmail
@profile_name = 'DatabaseMail'
@recipients = 'asdfasdfsdf@aafas.com'
@from_address = 'asdfasdfacasca@cc.com'
@query = 'Select * from failedjobs'
@subject = 'List Of Failed Jobs'
@attach_query_result_as_file = 1;
