Generally speaking, a suppression list is a list of leads that should not be contacted. It may be a list of individuals that have requested not to be emailed or called by your company. As such, they should be suppressed from any ongoing company communications. When running cost-per-lead advertising with 3rd party vendors, companies may want to reject any leads that are on their suppression file.
