My colleague and I have been A/B testing two separate campaigns created in Zoho. Each campaign is associated by a specific Email subject line and a list of contacts. We called into those contacts over the past week, logging each activity in Zoho. 

I am trying to run a report that shows the Call activity (Subject), time of call, contact name and the associated Campaign (Campaign A or Campaign B). When I try to run a Campaign Report, it only shows the initial email and not the call activity. When I try to run an Activity Report, the Campaign Name column shows up blank. 

To better illustrate: 

How can I best achieve this?

Thanks.
