In Advanced search select the ABM Filter.
Under Suppression you can add in either the Domains or Names of the Companies you are looking to exclude.
There are three ways to do this:
Type in the Domains or Names of the Companies you'd like to exclude in the relevant box. Hit the Enter key on your keyboard between each Domain or Name you're adding.
Copy the list of Domains or Company Names from its original source and paste it into the relevant box.
Use the Upload icon to upload a list of Domains or Company Names from an Excel file. Make sure it's saved in CSV format before you upload it!
💡Tip: Using domains instead of account names will give you the most accurate results.
