We have roughly 50,000 products and each one has a separate page. We would like to be able to track each one over time so that we can evaluate email marketing campaigns.

For example, we might send out an email encouraging customers to look at product "X". We would want to see how many hits the product "X" page got for a month before and a month after the email blast.

It looks as though the Navigation area might work, but I'm not sure if it can deal with 50,000 pages (and growing). Does anyone know if Google Analytics will be usable for us?
