Craft a proactive, persuasive letter that opens doors — even when no job is advertised
Sometimes the best career opportunities are the ones that never make it onto a job board. A well-written letter of interest lets you introduce yourself, show initiative, and position yourself for roles before they even exist.
In this guide, we’ll break down how to write a letter of interest for a job step by step — including tone, structure, examples, and tips backed by expert advice and authoritative sources.
What Is a Letter of Interest (and Why It’s Different from a Cover Letter)
A letter of interest (sometimes called a prospecting letter or letter of inquiry) is typically sent to a company that isn’t currently advertising a vacancy. It introduces you, highlights your skills, and shows why you’d be an asset to the team.
It differs from a cover letter, which responds to a specific advertised role. A letter of interest is proactive — it shows you’re forward-thinking and invested in that company specifically.

Key Principles Before You Write
Before you start writing, keep these principles in mind:
Research the company — know their mission, projects, and values.
Address the right person — ideally the hiring manager or team lead.
Keep it concise — one page is enough.
Connect your skills to their needs — show relevance.
Be enthusiastic but sincere — avoid empty buzzwords.
End with a clear call to action — invite further discussion.

How to Write a Letter of Interest for a Job: Step by Step
1. Contact Information and Header
Start with your name, address, email, and phone number. Below that, add the date and the recipient’s name, title, and company.
2. Opening Paragraph – Your Hook
Briefly introduce yourself and explain why you’re writing. Mention why you admire the company or what excites you about their work.
“My name is [Your Name], and I’m writing to express my interest in future opportunities with [Company Name].”
3. Middle Paragraph – Show Your Value
Explain your skills, experience, and achievements, and link them directly to the company’s goals or projects. Use specific examples and measurable results where possible.
“In my current role, I grew customer engagement by 35%, a result I believe could support [Company Name]’s new initiatives.”
4. Closing Paragraph – Call to Action
Thank them for reading and invite a conversation. Suggest an informational interview or express willingness to send more details.
“I would welcome the opportunity to speak with you about how my skills could support your future projects.”
5. Sign Off
Use a professional closing like “Sincerely” or “Kind regards,” then include your name and contact details again.
Extra Tips to Make Your Letter Stand Out
Tailor it to the company — avoid generic phrases or mass-sent letters.
Highlight mutual benefit — explain how your skills align with their mission.
Include one unique detail — like a project you admire or an idea you have.
Proofread carefully — errors can undermine a strong message.
Attach a concise CV or portfolio — this helps them see your full profile.
