Letter of Interest vs Cover Letter: What Is the Difference? (With Examples)

A letter of interest is one of the most underused tools in a job seeker's kit. It lets you get on an employer's radar before they advertise a role, and in competitive industries, that is often how the best jobs get filled.

The trouble is most candidates do not know the difference between a letter of interest and a cover letter, or when each should be used. This guide clarifies the distinction, walks through how to write a letter of interest, and gives you 4 full examples you can adapt.

What Is a Letter of Interest?

A letter of interest is a short letter sent to a company you want to work for, even when they have not posted a specific opening. It introduces you, explains why you are drawn to the organisation, and opens the door for future conversations.

It is also known as:

• Speculative application
• Prospecting letter
• Letter of inquiry

The goal is not to apply for a specific role. It is to put yourself on the hiring manager's radar before the role exists.

Letter of Interest vs Cover Letter: The Key Difference

These two documents are often confused but serve different purposes.

If you are responding to a job advert, you need a cover letter (or motivation letter). If you are reaching out speculatively, you need a letter of interest.

When to Send a Letter of Interest

1. You have found a dream company with no open roles

You read about a company you love but they have nothing advertised that fits your profile. A letter of interest keeps you on their radar for when the right role opens up.

2. You hear about a hidden opportunity

A contact mentions a role is about to open but has not been advertised. A letter of interest, sent before the public posting goes up, can put you first in line.

3. You want to offer a new role that does not yet exist

Some of the best career moves happen when a candidate creates a role by convincing the employer they need one. A letter of interest is the starting point.

4. You are exploring industry connections

If you want to move industries, a letter of interest to a target company can open informational conversations that eventually lead to job offers.

5. You are moving to a new city

Letting employers in a new geography know you are coming, with 3 to 6 months of notice, creates pipeline for your job search.

The Letter of Interest Structure

Keep it short. Half a page maximum. Use this 4-part structure:

Part 1: Header and greeting

Use the same professional header as your CV, then address the letter to the hiring manager or relevant team lead. For help finding a name, see our guide to addressing a cover letter without a name.

Part 2: Opening paragraph

State who you are, what you do, and why you are writing. Keep it to 2 to 3 sentences.

Weak: "I am writing to express my interest in your company."

Strong: "I am a data engineer with 4 years of experience building analytics platforms in fintech, and I have been following your work since your product launch last year."

Part 3: Body paragraph

Cover:

• Why this specific company (do your research)
• Your most relevant 2 or 3 qualifications
• A specific way you could add value

Mention a recent company event, product launch, hire, or piece of content you admired. This proves you have done research rather than sent a generic template.

Part 4: Closing paragraph

End with a low-pressure call to action. You are not asking for a job right now. You are asking for a conversation, a coffee, or to be kept in mind.

4 Letter of Interest Examples

Example 1: Letter to a Dream Company (No Open Role)

Dear Ms Chen,

I am a senior product designer with 6 years of experience in B2B SaaS, most recently at Figma. I am writing because I have been a user and admirer of Linear for 2 years and I would love to be considered if a senior product design role opens up in the next 6 to 12 months.

What pulls me towards Linear is the clarity of the design language and the unusually tight loop between engineering and design. Your post on "Built for Quality" last month resonated with how I think about product craft, and the recent work on the insights features suggests an appetite for the kind of data-dense interface design I enjoy most. My 6 years have focused on similar challenges: information-dense enterprise products where small design decisions have large usability consequences. I recently led the redesign of our developer console, which reduced average time-to-first-value from 14 minutes to 4.

I am not currently looking to move urgently, but I would love to be kept in mind when you next hire. If you have 20 minutes in the coming weeks for a casual call, I would value your perspective on the design team's direction. I am attaching my portfolio and CV for reference.

Thank you for your time,

Arjun Rao

Example 2: Letter Following a Hidden Opportunity Tip

Dear Mr Davies,

I am a finance analyst with 5 years of experience in energy infrastructure at Invesco. A mutual contact, Sarah Thompson, mentioned that your team may be expanding its renewable energy investment coverage in the coming months, and I wanted to reach out directly in case that is still the direction.

Your firm's move into clean infrastructure matches where I want to take my own career. I have spent the past 18 months specifically focusing on renewables, covering offshore wind and green hydrogen across European markets, and I have built the kind of sector expertise that takes time to develop. My current portfolio includes 6 active positions and 12 monitored opportunities, and I authored 3 primary research notes last year, one of which was picked up by the broader team.

I realise the timing may or may not be right. If your expansion is still planned, I would welcome a conversation about what you are looking for. If I am too early or too late, I would still value 15 minutes to introduce myself properly.

Thank you for considering this,

Tom Richards

Example 3: Career Changer Letter of Interest

Dear Ms Rodriguez,

I am a secondary school teacher with 7 years of experience in curriculum design and classroom delivery. I am writing because I am actively planning a move into corporate Learning and Development, and Unmind has been at the top of my list for the combination of mission, quality of content, and the fact that your L&D team has historically hired people from teaching backgrounds.

My reason for the move is simple: the core of what I do every day, designing learning experiences for specific audiences and measuring what works, is directly applicable to corporate L&D. Over my 7 years I have designed 3 full curricula from scratch, including a creative writing programme that was adopted across my borough. I have also mentored 12 newly qualified teachers, which is perhaps the closest analogue to what an L&D business partner does.

I would love to be considered for any openings on your content or learning design teams in the coming 6 months. In the meantime, would you have 20 minutes for a virtual coffee to share how my teaching background might translate into your world? I have attached my CV.

Thank you,

James Patel

Example 4: Geographic Relocation Letter

Dear Hiring Manager,

I am a marketing director relocating from London to Amsterdam in April, and I am writing because your agency's work on multi-brand B2B portfolios is the most relevant to my specialism in the Dutch market. I would welcome the opportunity to be considered for any senior marketing roles you may open in the first half of next year.

My last 8 years have been spent at SaaS marketing agencies, most recently leading a team of 12 across paid, content, and lifecycle marketing for 6 portfolio clients. Two of those clients, Personio and Deliveroo Amsterdam, were active in your market. I have a strong understanding of the Dutch B2B audience and I have working Dutch language skills (B1 written, B1 spoken).

I am not asking for an application now. I will be formally moved by April and fully available from May. If you are open to a brief conversation in February or March about the team's direction, I would value it. I have attached my CV and portfolio.

Thank you for considering this,

Anna Okonkwo

How to Write a Strong Letter of Interest

1. Research the company deeply

A letter of interest is a cold reach-out. Without research, it reads as lazy spam. Mention something specific: a recent product launch, a company value you share, a piece of content the leadership team wrote.

2. Get the name right

Always try to address the letter to a specific person. LinkedIn, the company website, and direct outreach are all fair game. For help, see our guide on how to address a cover letter without a name.

3. Keep it short

Half a page maximum. Your letter is unsolicited, so the recipient's patience is limited.

4. Make the ask low-pressure

You are not asking them to hire you today. You are asking for:

• A 20-minute call
• A coffee chat
• To be kept in mind
• Advice or a referral to someone else

Low-pressure asks are far more likely to get a reply.

5. Follow up once (but not more)

If you do not hear back in 2 weeks, one follow-up email is acceptable. After that, stop. Pushing harder damages your chances in the long run.

Common Mistakes in Letters of Interest

1. Sounding like a standard application

If your letter could be swapped in response to a job advert without changes, it is not a letter of interest. It should read clearly as "no advertised role, but interested in the company."

2. Generic research

"I love your company because it is innovative" is not research. Mention specific products, recent launches, or pieces of content.

3. Asking for too much

Asking for a job, a guaranteed interview, or a specific role creation in your first email is too much. Keep asks low-pressure.

4. Writing too much

A letter of interest should be short. Longer letters signal you do not respect the recipient's time.

5. No clear call to action

Finish with a specific, modest ask. Without one, the reader does not know what to do next, so they do nothing.

6. Not following up

Many people never get replies to their first email. One polite follow-up often doubles your response rate. More than one follow-up hurts you.

Letter of Interest vs Letter of Introduction

These are similar but subtly different:

• Letter of interest: Focused on a specific company, asking them to consider you for future roles
• Letter of introduction: More open networking tool, sent to a specific person to introduce yourself and explore a connection

For most career-related situations, a letter of interest is what you want. A letter of introduction is better suited to informal networking or introducing yourself via a mutual connection.
