A cover letter is a one-page business letter that you submit when applying for a job, along with your resume. It is a piece of persuasive writing that aims to convey to the employer why you are a great candidate for the role. Here are the key elements that should be included in your cover letter:

1. Contact Information: Begin your cover letter with your contact information, including your name, address, phone number, and email address. It should be in block style, on the left margin of your paper, towards the top.

2. Salutation: Address the letter to the hiring manager or recruiter by name, if possible. If you dont know their name, use a generic salutation such as "Dear Hiring Manager".

3. Introduction: In the first paragraph, introduce yourself and state the position you are applying for. You can also mention how you found out about the job opening.

4. Body: In the body of your cover letter, highlight your qualifications and experience that are directly applicable to the position you are applying for. Use specific examples to demonstrate your skills and achievements. Do not repeat all of the information contained in your resume. Instead, elaborate on resume items that are directly applicable to the position.

5. Closing: In the final paragraph, summarize your qualifications and express your enthusiasm for the position. Thank the employer for considering your application and request an interview or meeting to discuss your qualifications further. End with a professional closing, such as "Sincerely" or "Best regards".

6. Proofreading: Before sending your cover letter, proofread it carefully for errors in grammar, spelling, and punctuation. Have another person proofread it as well to catch any mistakes you may have missed.

In addition to the above elements, here are some additional tips to keep in mind when writing your cover letter:

• Tailor each cover letter to one specific position.
• Use industry jargon specific to your career field.
• Identify the employers key words and use them.
• Make all statements positive.
• Keep the cover letter to one page.
• Follow standard cover letter format.
• Use a simple, easy-to-read font style.
• Follow up with a phone call or email about five days after expected delivery.

Remember, your cover letter should articulate your qualifications and motivation for the position. Read the job description closely and research the organization. As you craft your cover letter, use examples that demonstrate your relevant skills, knowledge, and interests. The cover letter should be concise, clear, and well-organized.
