What does everyone do for error notification?

I know TCC has the ability to send an email when an integration succeeds or fails.  What about when an integration succeeds, but a few records within the data fail.  How do you handle this?  Is are you checking the result files each time it is run?  Do you have a system to read the file and parse the records for the failures?  I'd like to hear how others handle this on a routine basis.
