A cover letter sample checklist should include all the elements that a cover letter needs to have.

1. Length. Cover letter samples should be between one paragraph and one page.

2. Job Knowledge. The cover letter should show that you know what the job is expected to do, and needs to accomplish for success.

3. Reasons. The letter should prove that you have accomplishments and achievements in your past that prove you can be successful at the target job.

4. Call to action. The cover letter sample should end with the next step that the reader needs to take. This will probably be to call you for an interview.

5. Personality. Probably the most subtle of all the factors. Have you ever noticed how different writers can be identified by their “voice” even on a piece of paper? Your letter’s “voice” should reflect your intelligence and professionalism.
