Third-party tracking (e.g. Google Analytics, Omniture, Coremetrics etc.) can be added in the second step of the campaign setup. By inserting your email tracking parameters into the space provided, the tracking will automatically be added to the product URLs when a user clicks on a recommendation in the email.
The tracking parameters would look the same as what is appended to other hyperlinks in your email campaigns. For example:
utm_source=newsletter&utm_medium=email&utm_term=.... etc.
Please consult your Email Service Provider if you are unsure what email tracking should be appended to your email links.
