Instead of writing to inform people or to entertain them, you need to write your script as a way to create a conversation. You need to imagine what someone would say to another person and then put it on the page. Don’t be afraid if it feels like you’re talking to yourself — that just means you’re writing well.
When your customers call they’ll hear the right message, right at point of sale. Every time you press the hold button you’re opening up a world of opportunities for both your business and your customers. “More than 70% of business calls are placed on hold.” – AT&T “Callers stay on the line up to 25% longer when provided with On Hold Messaging versus dead air or background music and up to 17% longer than radio.” – Infomax “88% of callers preferred On Hold Messages to other options.” – MaxiMarketing

No one calls customer support to chit chat. They call because they have a problem and are likely irritated enough to get on the phone and ask about it. Odds are they’re not alone, so there’s a bit of a wait before your team can answer. If you were answering support calls, what would you want your frustrated customer listening to in the moments before you pick up?
The most engaging messages are slightly unique in nature. They combine a mix of clever scripting and music. Slight humour is often used to promote a product or service and is usually quite effective. It's also very important to choose both the written and spoken tone that appeals to the characteristics of your audience. If your target market is the younger generation, a script that includes slang words and is quite laid back would be an excellent choice. If your target market is primarily business professionals, then a more articulate choice of words would be more suitable.
