How to Write a Cover Letter

Why cover letters still matter in 2026

Even when a cover letter is optional, including one shows initiative and gives you a chance to explain why you are interested in the specific role and company. A good cover letter complements your resume by adding context and personality that a resume cannot convey.

A cover letter is not a repeat of your resume. It is a brief, targeted message that explains why you are a great fit for this specific role at this specific company. It lets you connect the dots between your experience and the employer's needs in a way that bullet points cannot.

In a competitive job market, a well-written cover letter can be the difference between two similar candidates. It shows that you care enough about the role to write something specific, and it gives the hiring manager a sense of who you are beyond your qualifications.

Cover letter structure

A standard cover letter has four parts. Keep it to one page — typically 250-400 words across 3-4 paragraphs. Every sentence should serve a purpose.

Tips for an effective cover letter

Address it to a specific person when possible. If the job posting does not name a contact, use "Dear Hiring Manager" or the team name. Avoid "To Whom It May Concern" — it feels impersonal and dated. You can often find the hiring manager's name on LinkedIn or the company website.

Keep it to one page or less — typically 250-400 words. Be specific about why you want this job at this company. Use the company's name and reference something you know about them — a recent product launch, a company value, a news article. This shows you have done your research.

Match your tone to the company culture — a startup may appreciate a more conversational tone, while a law firm expects formality. Look at the company's website and marketing materials for cues on how they communicate. Proofread carefully. A typo in a cover letter is even more damaging than in a resume because it undermines the very qualities a cover letter is meant to demonstrate.

Example cover letter

Dear Hiring Manager,

I am writing to express my interest in the Senior Product Manager position at TechFlow Solutions. As a product manager with 6 years of experience building B2B SaaS products, I was excited to see your focus on simplifying enterprise workflows — a challenge I have spent my career solving.

In my current role at DataPipe Inc., I led the development of a workflow automation feature that reduced customer onboarding time by 40% and contributed to a 25% increase in enterprise retention. I worked closely with engineering, design, and customer success teams to ship the feature on a 4-month timeline, and it became one of our top-cited reasons for renewal in customer interviews.

I am particularly drawn to TechFlow because of your commitment to making complex tools accessible to non-technical users. This aligns with my own product philosophy, and I would welcome the opportunity to bring my experience in user-centered enterprise design to your team.

I would welcome the opportunity to discuss how my experience aligns with your needs. Thank you for your consideration.

This cover letter works because it is specific, references the company, connects the applicant's experience to the company's mission, and includes a concrete achievement with numbers. It is not long, but every sentence adds value.

When to include or skip a cover letter

If the job posting explicitly says "no cover letter," follow the instruction. If there is no way to submit one (some application systems do not allow attachments), do not worry about it. In all other cases, including a cover letter is a good idea — even when it is optional.

When a cover letter is optional, many candidates skip it. Including one immediately sets you apart from those who did not bother. It shows initiative, effort, and genuine interest in the role — qualities every hiring manager values.

For certain roles, a cover letter is especially important: senior positions, client-facing roles, roles requiring written communication, and roles at mission-driven organizations where cultural fit matters. For these jobs, the cover letter is often a key part of the evaluation.

Common mistakes to avoid

Do not repeat your resume — the cover letter should add something new, not restate what the hiring manager can already see. Do not use a generic template that could apply to any job — each cover letter should be specific to the role and company. Do not write more than one page — hiring managers are reading many applications and will not appreciate a long letter.

Other common mistakes: addressing it to the wrong company (this happens more than you would think — always double-check), using a tone that does not match the company culture, focusing on what you want rather than what you offer, and including typos or grammatical errors. Proofread every cover letter as carefully as your resume.

Putting it all together

A strong cover letter is specific, concise, and tailored to the role and company. It complements your resume by adding context, personality, and a clear explanation of why you are interested in this particular job.
