How-To
Start by selecting the type of results you wish to display (Messages, Campaigns or Deployments). Apply filters if needed.
In the list, click the messages you wish to cumulate or compare. Then, click Compare or Cumulate depending on the case.
Comparing Results
Comparison results are quite simple. You have basic indicators for each message displayed side by side. The messages are represented by the vertical bars. 
Cumulating Results
Cumulating results are similar to Email Analytics. You can click the horizontal bars or the data to get precisions on the indicators.
There are other indicators lower in the page, such as engagement.
