Exclusion Lists help you exclude leads/companies from Smart Lists. While adding leads/companies to a Smart List from their Insights page, you can apply an Exclusion List and keep the leads/companies you don't want to see out of the picture.
Let’s see how you can use a Lead Exclusion List on the Leads page on the Discovery tab.
Using Lead Exclusion List
Go to the Discovery tab on the dashboard and then toggle the Leads tab.
Once you’re in the Leads tab, select your filters, and then your preferred Leads. Then, click on Add to list.
Select a smart list from the drop-down you’d like to add these leads to. You can even create a Smart List by typing in a new name, and clicking on “Create a new List”.
Click on the check box that says Select Exclusion List and add an already created Exclusion List. Once done, click Add.
And you’re done! If you click on the Lists tab, you now have your Smart List and the leads in the Exclusion List have been excluded.
