Leads Without Email in Last 30 Days
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)
