When you send in a CV, you will often be asked to accompany it with a covering letter. You should use the letter to sell yourself, explain why you are suitable for the role and describe how the information in your CV is relevant to the job that you're applying for.
There are two main reasons for having a covering letter. The first is to introduce yourself and to give your potential employer key details such as your contact details and which role you are applying for. The second is to encourage them to look at your CV or application form.
When you're writing the letter, you should keep it to a maximum of one side of A4 paper and emphasise your suitability for the role always use a computer to write it, unless the job advert asks for a handwritten letter include the job title or reference number of the job you're applying for get someone else to check it for spelling mistakes before you send it off.
Eg:
Dear Mr./Ms. Last Name:
I am interested in the Coordinator position advertised on XYZ. My CV is enclosed for your review. Given my related experience and excellent capabilities I would appreciate your consideration for this job.
