VerticalResponse will add the Google Analytics tracking parameters to all links pointing to the domain or domains you specified on the Analytics settings page. Any links that do not point to those domain(s) will still be tracked with the standard VerticalResponse reporting tool, but won't be included in your Google Analytics data.
On the sent email report in your VR account, you will see a Google icon next to every tracked link. This indicates that the specific URL was tagged with the required Google variables. Click this icon and you will be brought to the Google Analytics home page. Log into your account and find the relevant reporting under Traffic Sources | Campaigns
