Most cover letters fail not because of formatting, but because they don't answer the three questions every hiring manager is actually asking.

A cover letter that will get you an interview has to convey to the recruiter or hiring manager a clear picture of why you, why for that specific role, and why for that specific company. Many cover letters fail not because of the formatting, but because they don't answer those questions. An effective cover letter shows your knowledge of the company, your most impressive achievements, and your cultural fit. It stays concise and makes it clear that it's not a generic cover letter used for all applications.
Before writing your next cover letter, it helps to understand what hiring managers actually look for when they open one. They aren't scanning for all your professional biography details, but the five signals listed and explained in the table below.
| Signal | What It Shows | How to Demonstrate It |

| Specific company and role knowledge |
| Your genuine interest and tailoring, not mass-applying |
| Mention their mission, a product, or a team detail |
| Quantified relevant achievement | Proof of your impact | Mention an accomplishment relevant to the role |
| Culture fit | Your communication style and team fit | An anecdote or relatable detail (not a list of adjectives) |
| Clear and concise structure | Your respect for the reader’s time | Three to four short paragraphs, without repeating the whole content of your resume |
After summarizing the main aspects of a strong cover letter, the rest of this guide will show you how to incorporate these signals into yours, paragraph by paragraph.
In addition to knowing what hiring managers look for, it's important to learn what to include in a cover letter. The guide below provides more specific cover letter tips and breaks the writing process into clear, straightforward steps.
Step 1: Header
The header of your cover letter should include your contact information: your name, email, phone number, and your LinkedIn profile. Always use a professional email address because you have only one opportunity to make a first impression on the reader. When it comes to design and formatting, it's also a good idea to make the header consistent with your resume style, for a more polished effect.
Step 2: Opening paragraph
After addressing the reader, write a short reference to the company and the role you're applying for in the opening paragraph. That immediately signals you're not sending a generic cover letter for all your applications. If you don't know the recruiter's or hiring manager's name, it's okay to open with "Dear Hiring Team/Manager."
Step 3: Body paragraph 1
The first paragraph of the body of your cover letter should include your most relevant achievement. An impactful detail right away, which is directly relevant to the target role positions you as a strong candidate, and it should mention what you did, why it mattered, and what the result was. It's not a resume bullet point, so you have more liberty in your communication style.
Step 4: Body paragraph 2
The second paragraph of the body is reserved for your culture fit and motivation, so tell a brief anecdote or specific reason why this company and role match your professional direction. Don't demonstrate your soft skills by listing adjectives about yourself, but show how you work and what you value.
Step 5: Closing paragraph
Finally, use the last paragraph of the body to express again your interest in the position and your enthusiasm for the next phase, which is the interview you're hoping for. This is a call to action, and you want the hiring team to make the next move. That said, overly eager expressions, like "I would be thrilled beyond words," could ruin everything you achieved in the previous paragraphs, so keep it professional.
Step 6: Sign-off
Conclude with a simple "Best regards" or "Sincerely," followed by your name. It's a standard, professional way to end a letter, and nothing else is needed.

The cover letter example shown in the image below was written for a Project Manager applying to a mid-size SaaS company. The purpose of this example is to demonstrate all the discussed signals companies look for and the specific reasons behind each choice.
As with any strong cover letter, its content stays within one page. Before going into the details of this example, the overall structure illustrates all the above steps: it opens with a clear company reference, then moves to the body with a quantified delivery achievement, and closes with a forward-looking statement that signals genuine interest in the role rather than the job category in general.
