Letter of Interest: How to Write One That Gets Noticed (Examples)
A letter of interest is how you get on a company's radar before they post the job you want, or when they never post it at all. Done well, it turns a cold company into a warm contact. Done badly, it reads like spam. Here is exactly what a letter of interest is, how it differs from a cover letter, and how to write one that actually gets a reply, with two examples you can copy and adapt.
What is a letter of interest?
A letter of interest is a short, proactive note you send to a company you would love to work for, when there is no specific job posting you are responding to. It introduces who you are, explains why this particular company, and sketches what you could bring. You may also see it called a letter of intent, an inquiry letter, or a prospecting letter. They all describe the same thing: unsolicited interest, sent on your own initiative.
The point is not to demand a job. It is to start a conversation. Many roles are filled before they are ever posted publicly, through referrals and warm inbound. A good letter of interest puts you in that pile.
Letter of interest vs cover letter
People mix these up constantly, so here is the clean distinction:
- A cover letter responds to a posted job. There is a specific role and a job description, and your letter maps your experience onto its requirements. It is part of a formal application.
- A letter of interest is unsolicited. There is no posting. You are not applying to anything yet. You are reaching out because you want to work there, and you are making the case for yourself in the absence of a job description.
Practically: a cover letter says "here is why I fit this role." A letter of interest says "here is why I am drawn to your company, and here is the kind of value I could add. Can we talk?" The cover letter is reactive and tailored to a posting. The letter of interest is proactive and tailored to the company.
When to send one
A letter of interest is the right move when:
- You have a dream company but no open role. You want to be first in line when something opens, or to nudge them to create a role.
- You want an internal move. Expressing interest in another team or a step up, before the position is formally posted.
- You are changing fields and want to network in. Cold outreach to people doing the work you want to do next.
- A company is clearly growing (funding round, new office, product launch) and likely hiring soon, even if the careers page has not caught up.
It is the wrong move when there is already a posted role that fits you. In that case, just apply with a normal cover letter. Do not send a vague letter of interest when a direct application is available.
Research the company first
The single thing that separates a letter that gets read from one that gets deleted is specificity. Generic flattery ("I have always admired your company") is invisible. Before you write a word, spend fifteen minutes finding:
- One concrete thing they recently did: a product launch, a funding announcement, a blog post, a market they just entered.
- The right person to send it to: the manager who would own your work, by name, found on LinkedIn or the team page. Not a generic inbox.
- A real connection point: something about their work that genuinely overlaps with what you do or want to do. This becomes your hook.
How to structure a letter of interest
Four short parts, in this order:
- The hook. Open with the specific thing you found in your research. Name it. Show you actually pay attention to this company, not just any company.
- Why this company. Connect that specific thing to why you want to be there. Make it clear this note is not a mass blast.
- What you bring. One or two sentences on the concrete value you would add, with a real example or result. This is your proof, not a list of adjectives.
- A soft call to action. Do not demand an interview. Ask for something small and low-pressure: a short call, a coffee chat, or simply to be kept in mind. Easy to say yes to.
Keep the whole thing to 200 to 300 words. It should fit on one screen and be readable in under a minute.
Example 1: cold outreach, no posted opening
You want to work at a company that has no relevant job posted. You found the head of product on LinkedIn and noticed they just launched a self-serve onboarding flow.
Subject: Loved your new self-serve onboarding, quick note
Hi Priya,
I saw the self-serve onboarding flow Acme shipped last month, and the way you cut the
signup-to-first-value steps from nine to three is exactly the kind of activation work I
find most interesting. I am not sure you are hiring right now, so this is a note rather
than an application.
I am a product manager with five years of experience, most recently leading onboarding and activation at a B2B SaaS company, where I raised week-one activation from 31% to 48% over two quarters. The problems you are working on at Acme are the ones I want to spend the next few years on.
If a role that fits opens up, I would love to be on your radar. And if you are open to it, I would happily grab fifteen minutes to hear how you are thinking about retention next. Either way, keep up the great work. My resume is attached for context.
Best,
Sam Rivera
Example 2: interest in an internal move
You already work at the company and want to move to another team (or signal interest in a promotion) before any role is posted. Send this to the manager of the team you want to join.
Subject: Interested in the data platform team
Hi Marcus,
I have been following the data platform team's work on the new event pipeline, especially
the migration off the legacy ETL jobs, and it is the direction I most want to grow into. I
wanted to flag my interest directly rather than wait for a formal opening.
Over the past two years on the analytics team I have shipped most of our reporting infrastructure, including the dbt models your team now pulls from, so I already know a good chunk of the data and the stakeholders. I think I could ramp quickly and take real work off your plate within the first month.
Could we find twenty minutes to talk about whether there is a fit, now or down the line? I am happy to work it out with my current manager if so. No rush, I just wanted you to know I am genuinely interested.
Thanks,
Jordan Lee
Following up
Most letters of interest do not get a reply on the first try, and that is normal. Wait seven to ten business days, then send one follow-up. Reply to your original message and add a small piece of new value: a relevant article, a recent milestone of theirs you noticed, or a tightened one-line version of your pitch. One follow-up is professional. A third or fourth is not. If there is no reply after the follow-up, let it go and keep your search moving.
A letter of interest opens a door, but keep applying
A strong letter of interest can get your foot in the door at a company you love. But it is a long game, and any single note is a long shot. While you wait on the dream company, you still need to apply broadly to roles that are actually open, and that is the slow, repetitive part: the same name, work history, and education typed into yet another Greenhouse, Lever, or Workday form, five to ten minutes each time.
Lentra fills those applications in about 20 seconds. You save your profile and resume once (sign in with Google), and it completes the standard fields, work history, education, and screener questions on the company's real careers page, then drafts the free-text answers from your actual resume. You review everything and submit it yourself. It is free, with no quotas. So the cold outreach can stay personal while the high-volume applying stops eating your evenings.
