Some services provide numbers that have been involved in litigation, so those are the ones you should definitely remove from your lists.If your lists are hyper-focused, you might manage to get by with fewer removals from the DNC list.There are also non-DNC-related methods available, such as direct mail and digital marketing.

The BRRRR method and creative financing are game-changers!
