In reply to Ronan.

Thanks for the comment, Ronan. We do use tracking links to measure which newsletter items generate the most interest. In fact, it's those metrics that revealed the popularity of the "SAS tip" items, and led us to create this tips-centric edition. SAS is very keen to have metrics to analyze, as you might imagine. We use this information to create more relevant content for our readers. However, we are also sensitive to privacy concerns and of course we comply with the various regional rules that govern the collection/use of tracking information.
