How does it make you feel when a customer lets you know that you did something above and beyond the call of duty? How about when one of your employees gets a thank you note with appropriate laudatory remarks, how does he feel and what does it do for your "I-hired-that-guy; how-cool-am-I” feelings? Why not share that testimonial with those callers who are listening to your on hold messaging when they call? Guaranteed those callers will ratchet up their feelings about your organization a few notches. And that will reinforce their decisions to call you and to want to do business with you.
