How do you track marketings influence on Customers?
We are turning down the path of what is the best way to attribute marketing's influence on Customers; specifically renewals/cross-sell/up-sell. There has been thoughts that responding to one Marketing email campaign isn't enough to assign marketing an influence. There has been thoughts to create a separate scoring structure similar to a lead score, but would be for contacts. Also, we've thought about concatenating behavior of a customer within campaigns and web visits within a certain time frame could contribute success. What do you do? And does Sales buy it?
