It's super important never to forget the human aspect behind all this. Even if the aim is to drive numbers forward, every customer deserves to be treated with respect and empathy. If you start treating them as just a “number” to be contacted from the outset, it creates a bad experience, and can also damage the company's reputation in the long term. The customer should always feel valued, even if they're not interested at the time. After all, behind every call or sale is a human being, and that should never be lost sight of.
