Dear Mr. Rodriguez,
I found your advertisement on your company website, and I know that I am the right person for this Client Service Manager position. This is why I submit my application today.
My experienced in the customer service field has taught many valuable lessons for career growth to include the number one: always service the client to their satisfaction, and if you can-exceed those expectations. This said, I have over nine years as a Client Service Manager with three years of experience as a Rep before that-and I know how to make people happy with the product and the service. Moreover, I know how to get business, and also retain the business and uphold fine reputations. My track record speaks for itself.
It would be more than a pleasure to meet with you and learn more about your opportunity. Please call me at (555)-555-5555 as soon as you can to schedule this meeting.
