Tracking reachouts


My sales team is currently having issues to track our total number of reachouts. We track each reachout by updating a date column when the reachout is completed. A filter is then used to track the reachouts in the last 30 days.

However, I recently noticed that if the same row is contacted more than once in the last 30 days it wont add the accurate number of reach outs. Does anybody have a solution for this?
