Dear Mr. Smith,
With reference to your advertisement on www.careerjet.com, I would like to apply today for your Service Delivery Manager position. I have included my resume for your convenience.
I believe I am the right candidate for this position for a number of reasons. To begin with, I have worked as a Service Delivery Manager for the past three years at Dell Inc, and a Service Delivery Driver for six years prior to that. This said, I am well equipped with the right experience and an impeccable delivery, service, and safety record to offer.
Please give my resume with enclosed career history a review, and then contact me for more details on what I can bring this position at your company. I can also furnish a number of recommendations from my colleagues and supervisors to help in your consideration, at your request. Thanks so much for your time, and please contact me at (555)-555-5555.
