What does the Actions statistic mean?

The Actions statistic represents any interaction with the campaign, including views, clicks, opt outs, and replies.

It is included as the last sub-navigation item in the Interaction tab as there was some debate in the email marketing industry about which statistics should be used to track and measure campaign success. In the event the industry adopts this "Actions" statistic as opposed to "Views" as a standard, the system is poised to be able to address that change. However at the moment, "Views" and "Clicks" are still the most standard statistics used to track campaigns.
