Here's something easy and useful for you. When you send a ClickDimensions email and associate a Microsoft CRM campaign to your ClickDimensions Email Send record we create an automatic association with your Google analytics tracking if you use Google analytics (if you don't use Google analytics you can set up a free account here http://www.google.com/analytics/).
After you send your ClickDimensions email, you can go into the Google analytics account for your web site and click on 'Traffic Sources' and then 'Campaigns' to see the traffic that your email brought to your site.
This will show you how many visits your ClickDimensions email brought to your site, the average time on site, bounce rate, etc.
It is really that easy. Happy Marketing!
