A cover letter is a short document (typically 250–400 words) that accompanies your resume. Its purpose is to introduce you, highlight your most relevant skills, and explain why you're a good fit for the job.
| Resume | Cover Letter |
|---|---|
| Lists skills and experience | Explains how they apply to the job |
| Structured and factual | Personal and persuasive |
| Standard format | Customizable |
For example, if you're applying for a technical role, your resume might list programming skills, while your cover letter explains how you used them to solve real business problems.
Think of your cover letter as your “sales pitch.” It connects your experience directly to the employer’s needs.
If you're unsure how to structure your resume alongside your cover letter, tools like professional resume creator tools can simplify the process.
The short answer: No—but often you should include one anyway.
Even when employers don’t explicitly ask for a cover letter, submitting one can set you apart. Many candidates skip it, which gives you a chance to stand out.
| Scenario | Need Cover Letter? |
|---|---|
| Job posting requires it | Yes (mandatory) |
| Optional submission | Recommended |
| Quick apply (no option) | No |
| Referral-based application | Optional but useful |
Assuming “optional” means “unnecessary.” In reality, optional often means “expected but not required.”
If you're applying through platforms like Indeed resume builder tools, you may notice that many candidates skip the cover letter—this is your opportunity to gain an edge.
There are situations where skipping a cover letter can immediately disqualify your application.
For example, organizations like the UN often require detailed cover letters. You can explore examples such as UNHCR cover letter samples to understand expectations.
For regulated industries like healthcare, tailored letters are crucial. See examples like Medicare cover letter samples for guidance.

While cover letters are valuable, there are cases where they are not necessary.
Sending a generic cover letter everywhere—even when it's not needed. This can look lazy and reduce your chances.
If you're applying for practical roles like mechanics, your experience may matter more than a cover letter. See examples like mechanic resume samples.
Even when optional, a cover letter offers significant advantages.
| Without Cover Letter | With Cover Letter |
|---|---|
| Generic application | Personalized application |
| Less engagement | More compelling story |
| Lower visibility | Higher recruiter interest |
Use your cover letter to highlight soft skills that are hard to show in a resume.
