CX Engage is what the name implies, an engagement tool. It is not robust in publishing. Publishing has basic scheduling functions for most channels. If you are looking for something more in-depth with regards to creative editing, you won't find it here.
With regards to reporting, capabilities are a bit light. 4 basic infographic options with no widgets available to enter contextual data to make the reports robust. Instead, those added features are circumvented with the purchase of CX analyze (Studio/Designer). Review collected by and hosted on G2.com.
