Telemarketing lists make a different in cold calling success

With any telemarketing campaign, the contact list (or telemarketing list) can enhance or inhibit your success rates.  If you are purchasing your contact list from an outside vendor, make certain you understand how that vendor acquires their information.  You should also record success rates within each list.

If you purchase contact lists from multiple vendors, you should also compare and contrast success rates between contact lists and each vendor.  Use the lists and vendors that provide the greatest success rates.
