Letter of Interest: How to Write One (Sample and Template)

Not every great job is advertised. A letter of interest lets you contact a company you'd love to work for, even when there's no open role that fits you. Done well, it can put you on their radar before a position is posted.

What is a letter of interest?

A letter of interest (also called a prospecting letter) is a short message to an employer explaining why you want to work there and what you could contribute. Unlike a cover letter, it isn't tied to a specific job posting.

Letter of interest vs cover letter

• Cover letter: responds to a specific job ad.
• Letter of interest: introduces you to a company without a specific opening.

When to send one

• You're very interested in a specific company.
• The company is growing or has recently announced new projects.
• You have skills that clearly match their work.
• You want to work in a niche field where roles are rarely advertised.

Who to send it to

Send it to a real person, ideally the hiring manager or head of the team you want to join. You can often find names on LinkedIn or the company's website. A recruiter or talent acquisition contact also works.

How to structure a letter of interest

1. Subject line: "Letter of interest: [Your field] at [Company]".
2. Opening: who you are and why you're writing.
3. Why this company: something specific you admire.
4. What you offer: two or three relevant skills or achievements.
5. Call to action: ask for a short conversation, not a job.
6. Sign-off: thank them and include your contact details.

Keep it under 300 words.
