What Should You Put on a Cover Letter?

A strong cover letter must contain specific elements that clearly communicate your value. Recruiters typically scan cover letters in under 30 seconds, so clarity and structure are essential. Below are the core components every professional cover letter should include.

Essential Elements

• Contact information (name, email, phone number)
• Employer details (company name and hiring manager if available)
• Strong opening paragraph with job intent
• Value proposition (why you are suitable)
• Relevant achievements tied to job requirements
• Call to action (request for interview)

For example, if you're applying for specialized roles like internships, you can study real-world formats such as this talent agency internship cover letter example to understand industry expectations.

Best Structure of a Cover Letter (Step-by-Step)

Structure determines readability and impact. A well-organized cover letter helps hiring managers quickly understand your qualifications. Below is the most effective professional structure used by recruiters.

Practical Writing Tips

1. Keep paragraphs short (3–5 lines max).
2. Use action verbs like “developed,” “managed,” “implemented.”
3. Focus on outcomes, not just responsibilities.
4. Maintain professional tone without being robotic.
5. Customize for each job application.

If you're a recent graduate, you may also benefit from reviewing a structured engineering graduate cover letter sample, which demonstrates how to highlight academic and internship experience effectively.

How to Tailor Your Cover Letter for ATS and Employers

Modern hiring systems use Applicant Tracking Systems (ATS) to filter applications. If your cover letter does not contain relevant keywords, it may never reach a human recruiter. Tailoring is therefore essential.

Checklist: ATS-Friendly Cover Letter

• Uses job title in first paragraph
• Includes 5–10 relevant keywords
• Avoids complex formatting
• Focuses on measurable achievements

Example of Tailoring

Instead of saying “I have marketing experience,” say “I increased social media engagement by 45% through targeted advertising campaigns.” This approach works especially well for roles such as those shown in this advertising resume guide.

Industry Examples and Internal Resources

Different industries require different cover letter approaches. A one-size-fits-all document rarely works. Below are examples of how cover letters vary depending on the field.

• Creative roles: Focus on portfolio and storytelling
• Corporate jobs: Emphasize measurable achievements
• Entry-level positions: Highlight education and internships
• Real estate or rentals: Emphasize reliability and responsibility

For example, if you are applying for housing-related positions or property management roles, reviewing a rental resume template guide can help you align your cover letter with industry expectations.

Similarly, if you're preparing for career fairs, understanding how to write a resume for job fairs will help you create a consistent personal brand across documents.

In global or policy-related fields, even documents like this Paris Agreement summary guide show how structured communication is essential for clarity and persuasion.
