Aged leads are records that have already been sold or worked, then packaged again at a lower price. The discount reflects the decay: people change jobs, numbers get reassigned and emails bounce.

They can work for high volume consumer offers where the cost per dial matters more than the connect rate. In B2B outbound they usually cost more in rep time than they save on the invoice.

Ask when each record was last confirmed, not when it was collected. That date is the one that predicts whether the phone rings through to the right person.
