Writing an Effective Cover Letter

A strong, tailored cover letter remains one of the most effective ways to stand out in competitive fields such as PR, Communications, Public Affairs and Marketing. According to Resume Genius’s cover letter statistics, even when a cover letter is marked as “optional,” most hiring managers still read them. In fact, 83% say they review the majority of cover letters submitted.

And while not every job advert requires one, a polished, well-structured letter can make a meaningful difference:

49% of hiring managers report that a compelling cover letter
can tip the balance in favour of offering an interview. 

In a crowded market, it’s a valuable opportunity to showcase your motivation, communication skills and fit for the role.

What Is a Cover Letter and Why It Still Matters

A cover letter is your opportunity to introduce yourself, highlight relevant skills and experiences, and explain why you’re a good fit for a specific job. Even in 2025’s market, where many applications are processed quickly — sometimes by AI screening tools — a well-crafted cover letter remains a powerful asset.

Think of it as a brief, persuasive pitch: it complements your CV by giving context, demonstrating communication skills, and showing enthusiasm for the role.

How to Structure a Strong Cover Letter

Employing a clear, consistent format helps hiring managers scan your application quickly. A typical cover letter should include:

Header and Contact Details

  • Your name, professional email, and phone number (and postal address if sent by post).
  • Date of application.
  • Recipient’s details — company name, hiring manager’s name and title (if available).

Salutation

Avoid generic greetings like “To Whom It May Concern.” Where possible, find the hiring manager’s name on LinkedIn or via the job advert and address them directly. If that’s not possible, you may address it to the relevant department lead.

First Paragraph: Why You’re Writing

Begin by stating the role you’re applying for and how you found it. Use a compelling opening sentence to express enthusiasm about the company or organisation. This sets the context and encourages the hiring manager to read on.

Second Paragraph: Brief Professional Overview

Give a concise summary of your background that is relevant to the role. Tailor this to highlight why you are a good fit; not your entire CV, but core skills, relevant experience, and genuine interest in the company or sector.

Third Paragraph: Selective Achievements & Fit

Rather than repeating your CV, pick one or two key achievements or experiences that demonstrate value. Show measurable impact (e.g. “increased engagement by X%,” “managed a team of five,” “delivered a campaign on deadline”) and link them to what the employer is looking for. This shows you understand the role and can deliver.

Note: If the role involves creating content, campaigns or messaging, consider referencing examples from your portfolio. If you work in marketing, reviewing Why Every Marketer Needs a Portfolio can help you choose the most relevant work to highlight.

Fourth Paragraph: Enthusiasm for the Interview

Express your eagerness for the opportunity to interview — being proactive demonstrates professionalism and interest.

Closing and Sign-Off

Close formally: if you’ve addressed someone by name, sign off with “Yours sincerely”; if not, use “Yours faithfully.” A signature, handwritten or e-signature, adds a personal touch.

Additional Tips for a Standout Cover Letter

  • Use a professional format: clean font (Arial, Calibri, Times New Roman), 10–12 pt size, and single-page length.
  • Mirror the tone and style of the company: review the job ad for clues: is it formal, creative, concise, or conversational? Reflect that in your language and structure.
  • Use relevant keywords: Many employers use keyword filtering. Include skills or specialisms from the job description naturally, but avoid keyword stuffing.
  • Address formatting and design: A poorly formatted letter can be off-putting. Use clear spacing, standard margins, and a clean layout.

Common Mistakes to Avoid

  • Submitting a generic letter you reuse for all jobs rarely impresses. Tailor each letter individually.
  • Repeating your CV word-for-word… the cover letter should complement, not duplicate.
  • Using overly long paragraphs or complex sentences. Brevity and clarity matter.
  • Ignoring instructions in the job advert (e.g. preferred file type, additional questions).

Even if it’s optional, a well-written cover letter can help you stand out from the competition and show genuine interest in the role.

Professional, but authentic. Share your genuine interest in the role, culture or mission of the organisation — but avoid overly emotional or casual language.
