Is there a way to run a report to show how many emails a lead received in a given time period?

I need to know how many emails a lead is receiving at any given time (weekly, monthly, etc.), so I created a SmartList in the lead database section and used the filter 'Was Sent Email.' The report gives me what I need, but I have to click on the leads and then their activity logs to see what campaigns they received. Is there a way to run the report so the names of the campaigns are shown under each lead, without clicking on the lead's activity log? Thanks!
