You’ve found your dream company — but there’s no job posting in sight. Do you wait for an opening, or do you take the initiative and reach out? That’s where a letter of interest comes in, where it lets you introduce yourself to a potential employer, express enthusiasm for the organization, and position yourself as a strong candidate for future roles. It’s not a job application in the traditional sense — it’s a proactive way to get your name in front of decision-makers.
In this guide, we’ll cover everything you need to know about how to write one, show you a sample and share how we help job seekers create attention-grabbing letters that open doors.
What Is a Letter of Interest?
It is a formal letter that expresses your desire to work for a company, even if there’s no advertised position. Sometimes called a prospecting letter or expression of interest, it highlights your skills, experience, and motivation while showcasing your knowledge of the organization.
Unlike a cover letter (which responds to a specific job posting), it focuses on your potential value. It answers the question, “Why should we consider you for future roles?”
These letters are a powerful networking tool for professionals seeking opportunities before they become public.
Why Write a Letter of Interest?
Here are key reasons why writing a letter of interest is worth your time:
- Get Ahead of Openings – Companies often fill roles internally or through referrals before posting jobs publicly. A well-timed letter can position you early.
- Show Initiative – Reaching out without being prompted demonstrates confidence and drive.
- Build Relationships – Even if no role is available now, your letter might keep you top-of-mind for future opportunities.
- Expand Your Network – HR teams or hiring managers might refer you to other departments.
- Highlight Transferable Skills – You can frame your expertise to fit potential roles within the organization.
Demonstrating initiative through direct communication often leads to faster career advancement.
How to Write a Letter of Interest?
A great letter of interest sample follows a clear structure that balances professionalism and personality. Below is a proven framework you can use.
1. Start with a Strong Opening
Begin with a professional greeting and immediately state your purpose. Mention the company name and express genuine enthusiasm.
Example:
Dear [Hiring Manager’s Name],
I’m writing to express my interest in potential opportunities at [Company Name]. As a dedicated marketing professional with over six years of experience driving digital campaigns, I’ve long admired your brand’s innovative approach to customer engagement.
2. Highlight Your Value
Use the next paragraph to summarize your key skills, achievements, and what makes you an asset. Quantify your results when possible.
Example:
In my current role as a Digital Marketing Manager at [Current Company], I’ve led a team of five specialists to achieve a 40% increase in online engagement through targeted campaigns. I thrive in creative, fast-paced environments and would love to contribute those same skills to your team.
3. Show Knowledge of the Company
Demonstrate that you’ve done your research. Mention something specific about the company’s culture, mission, or achievements.
Example:
I’ve been particularly impressed by [Company Name]’s commitment to innovation and community engagement. Your recent sustainability initiative aligns with my professional values and inspires me to contribute meaningfully to your continued success.
4. Close with a Call to Action
End on a positive note by requesting an informational interview or expressing openness to future communication.
Example:
I would appreciate the opportunity to discuss how my skills could contribute to your upcoming projects. Thank you for considering my letter of interest. I look forward to staying in touch and exploring ways to collaborate in the future.
Sincerely,
[Your Name]
