A cover letter should be written in traditional business format. Your return address, the address of the person receiving the letter and then the appropriate salutation.

Following the basics, the body of the letter should be as follows:1. Seize Attention - In the first sentence grab the manager's attention. Tell then you want an appointment.

2. Pique their interest - Whet the manager's interest by explaining why you are writing to this particular company. Due research if necessary.

3. Get down to business - Explain that you would like to "learn about the career opportunities in the company or department."

4. Explain what's special about you - If you just graduated school, if you just got out of the service, or if you have hands-on experience. Then show that you're qualified to handle the job. Sell yourself.

5. Wrap it up - Since the manager won't call you, set a time that you plan to call. Make sure you call.
