I worked with CVPA today to review their email campaign-tagging. They are concerned that their email traffic may not be counted correctly in their analytics.
We were able to find and identify website traffic from a number of different campaigns, though not as much traffic was indicated in the click-through rates in their email software: Constant Contact (which is not unusual).
CVPA is concerned that the Constant Contact software may be stripping the campaign parameters out of the links in the email. I pointed them to this article in the Constant Contact knowledge base about use of Google Analytics, which seems to indicate that it can be done successfully.
CVPA will review their process and we will closely watch the analytics around the next email to see if we can track its effect on website traffic as we would expect.
