We learned today that it will cost $120/user per year to get access to the Account Insight plug-in (Marketo ABM is also required). It should be noted that if you have ABM and MSI, the charge is for any seats needed beyond your MSI seats. If you don't have MSI, the charge begins with the first seat requested.
My question is as follows: let's say we have 100 MSI seats. How will Marketo know which sales folks have a seat in MSI to validate access to the Account Insight plug-in? Is a login initially required to begin using the plug-in?
