If you’ve ever worked in telemarketing or cold calling, you might have had your supervisor come by and remind you put on a smile when you’re on the phone with customers. Obnoxious? Yes. Weird? Kind of. But not without it’s merits. “Smile while you dial” is the ultimate customer service best practice. Why? Because customers can hear you smile. As humans, we pick up on vibes and adjust our own behavior to other people’s emotional cues. This you may already know. But what if I told you that your tone of voice when you’re talking to your customers directly influences your company’s bottom line? Believe it or not, it does.
