Reveal Loop in Salesforce is a newly introduced tool that combines Clearbit's IP address lookup service, Reveal, with its Prospector service, enabling organizations to build prospect lists from companies that have anonymously visited their website. This integration allows users to create targeted lists from companies, such as those with over 200 employees, who have visited their site within the last day, and then deduplicate these lists against existing accounts in Salesforce. The tool is particularly beneficial for crafting highly personalized and targeted email campaigns, as demonstrated by Segment's growth team, which achieved a 55% open rate and a 200% increase in outbound email engagement by targeting website visitors. Reveal Loop aims to enhance the efficiency of sales teams by giving them the capability to transform anonymous web traffic into actionable sales leads within Salesforce.
