Salesforce administrators can create a report that will show if a Lead has gone “cold” and not received any email from a Salesforce User within a designated amount of time. The report data can also be viewed in a dashboard graph shown below. In this example, if a Lead hasn’t received an email in the last 30 days, and not been converted to a Contact, their name will be listed.
Be able to view how many leads that have NOT been contacted in the last 30 days. (Just another way to style the same report)

Please note there are limitations on custom reports in Salesforce.com. Group edition does not allow custom reports. Visit Analytical limits per Salesforce Edition for more information.
