With the addition of the Email/Product Dashboard in v2.2 of Core iQ, you might be wondering how you can best calculate your total spend in the platform. While we don't have a cumulative sum anywhere in Core iQ, you can easily leverage the Outbound Communication Status report to see how many templates you have Processed during a given month. Simply select your dates in the Creation Date field (it defaults to the previous month) and select a Current Status of Processed. This will give you a total list of all the items sent from Core iQ during a month, along with the per-piece price for each item. Simply multiply the total number of items by their per piece price, and you'll have your total spend.
This should get you a fairly close estimate for your monthly spend, minus our bulk pricing discounts on print items.
