Add the ability to select multiple campaigns (up to 4(?) and produce a graph that compares the opens / clicks / bounces for each campaign.
User should be able to easily select whether to compare the bounces unsubscribes, clicks etc.
With our July 2015 release, you can now compare up to 24 campaigns side-by side. See the open / click / bounce rates.
You can also compare attrition rates (how many contacts were lost due to bounces, unsubscribes and spam complaints) and engagement rates.
