When you submit a job application, your resume tells the story of what you’ve done. Your cover letter reveals why you’re applying and how you can contribute. In this guide to Cover Letter Basics, you’ll learn how to craft a compelling letter that complements your resume, shows your fit for the role, and captures hiring‑managers’ attention.

Why a Cover Letter Still Matters

Even in an age of online forms and digital profiles, a well‑written cover letter can set you apart. According to career services at the University of Cincinnati:

“A cover letter introduces you to potential employers, highlights your qualifications, and explains why you’re a good fit for the position.” 

Similarly, the Columbia Career Education notes that a strong cover letter:

“highlights your qualifications, showcases your motivation, and reflects your voice and communication skills.” 

In other words: the cover letter is your chance to make the case beyond bullet points.

Key reasons to include a cover letter:


Structure & Format: The Foundation

Getting the format right ensures that your reader stays engaged. Here’s a breakdown of the standard structure:

Header / Contact Info

Your name, address (or city/state), phone number, email. Include date and recipient (if applicable). 

Greeting

Address the hiring manager by name if possible (e.g., “Dear Ms. Smith”). If the name isn’t available, “Dear Hiring Manager” is acceptable. Avoid “To Whom It May Concern.” 

Opening Paragraph

State what position you’re applying for, how you found it, and why you’re interested. Grab their attention and show relevance from the start. 

Body Paragraph(s)

Connect your background to the job. Choose one or two genuine achievements or examples and explain how they prepare you for this role. Avoid simply repeating your resume. 

Closing Paragraph

Reiterate your enthusiasm, thank the reader, and include a call to action: e.g., you’d welcome the opportunity to discuss how you can help. Keep it brief and confident. 

Signature

Use a formal closing such as “Sincerely,” followed by your typed name. If sending a hard copy, leave space for your signature. 


Best Practices for Content

Here are practical guidelines to ensure your cover letter is polished and effective:

1. Tailor it to the job and company

Generic letters are easily spotted. Instead:

2. Use specific examples

Rather than: “I’m a strong communicator.”

Write: “In my role at X Corp, I led weekly cross‑department meetings, improved team alignment, and reduced miscommunication issues by 20%.”

This kind of detail gives credibility. 

3. Keep it concise

Stick to one page (or one screen). Several sources suggest 250‑400 words (or three to four paragraphs) is ideal. 

4. Format and style matter

5. Proofread, review, tailor


Common Mistakes to Avoid


Sample Outline that covers the cover letter basics (Template)

Here’s a simple outline you can use as a reference:

[Your Name]
[City, State] | [Phone] | [Email]
[Date]

[Recipient Name]
[Title]
[Company Name]
[Company Address]

Dear [Recipient Name],

Opening paragraph: State role, how you found it, why you’re interested.

Middle paragraph(s): Highlight 2–3 relevant experiences/skills. Show how they’ll help in this role.

Closing paragraph: Reaffirm interest, thank them, invite next steps (interview/discussion).

Sincerely,
[Your Name]

Use this as a scaffold—then fill in the specifics, polish language, and customise for each application.
