What Is a Cover Letter?
A cover letter is a short document or email sent together with your resume. It introduces you to the employer, explains your interest in the position, and highlights why you're a good fit.
Unlike a resume, a cover letter gives you the opportunity to speak directly to the hiring manager and show genuine enthusiasm for the company.
Do You Always Need a Cover Letter?
Not always. Some employers don't ask for one, while others make it a required part of the application.
Even when it's optional, including a thoughtful cover letter can help you stand out from other applicants.
When a Cover Letter Is Most Helpful
- You're changing careers.
- You have little or no professional experience.
- You're applying for an international position.
- You want to explain employment gaps.
- You want to demonstrate genuine interest in the company.
Simple Cover Letter Structure
A professional cover letter usually follows this structure:
- Greeting.
- Introduce yourself.
- Explain why you're interested in the position.
- Describe why you're a strong candidate.
- Thank the employer.
- Sign your name.

Frequently Asked Questions
How long should a cover letter be?
Around 150–250 words is ideal. Recruiters usually spend less than a minute reading it, so keep it concise.
Should every job application include a cover letter?
If the employer allows it, including a cover letter is usually a good idea because it helps you stand out from other applicants.
Can I use AI to write a cover letter?
Yes, but always personalize the final version. Recruiters can often recognize generic AI-generated text.
Should I send a cover letter as a PDF?
If the employer asks for attachments, PDF is usually the safest choice because it preserves formatting. If there's a message box in the application form, paste your cover letter there instead.
