Recommendation for app to track promotion performance

Just wondering what people use for tracking and cataloging promotion performance? Such as one off email sales with a coupon etc. Low-tech with spreadsheet or something more advanced? I’ve tried Funnelytics and Wicked Reports — the former doesn’t always work and the latter — while it’s supposed to be able to attribute sales to email blasts — is overly complex. Any suggestions would be great.
