Letter of Interest: How to Apply to a Company With No Openings

A letter of interest is a short letter or email that tells a company why you want to work there and what you can do for it, even though no job is advertised. It is also called a speculative application (UK) or an unsolicited application. It works best at small and mid-sized firms and in fields that rarely advertise.

Key takeaways

• A letter of interest answers no job posting. It pitches one named person on one specific way you can help, then asks for a short conversation.
• It works best at small and mid-sized employers and in fields that rarely advertise, such as media, arts, design, charity and environment work (Prospects, Cambridge Careers Service).
• Check the careers page first. If a matching role is listed, send a cover letter for that role instead.
• Keep an email to about 100 to 200 words and a letter to one page. Follow up once, after one to two weeks.
• We could not find a study behind “80% of jobs are never advertised”, so plan for modest odds and send a few well-researched messages, not hundreds of generic ones.

If a company has posted a role that fits you, apply to that listing with a tailored cover letter; that is the work an AI job application bot and an AI cover letter generator are built for, because both work from a posted job. A letter of interest is the other route: you write to the employer before a role exists and ask to be considered, so the research and the facts have to come from you.

What is a letter of interest?

A letter of interest is an unrequested letter or email that tells an employer you want to work there, summarizes what you offer and asks to be kept in mind for roles that are not yet posted. The University of Cincinnati describes it as a document that expresses your desire to work for a company even if no specific opening is advertised.

The name changes by country. U.S. career centers and The Muse say “letter of interest” (The Muse adds that some call it a letter of intent). UK sites such as Prospects and the University of Cambridge Careers Service say “speculative application”. Elsewhere in Europe, employers that translate their own term (such as the German Initiativbewerbung or the French candidature spontanée) often say “unsolicited application” or “open application”. The email version is also known as a “cold email for a job”.

One caution: some employers and schools use the term for a posted job, for example by asking for a “letter of interest” with an application. Then it is a cover letter for that job, and our cover letter examples apply.

What is the difference between a letter of interest and a cover letter?

A cover letter answers a posted job, and a letter of interest answers no posting. The table follows the University of Cincinnati, The Muse and Coursera, which agree on the split (read October 2026).

The Muse notes that a letter of interest does not always include a resume, while Prospects says a speculative application usually comes with a CV (the UK word for a resume) and a cover letter. Attaching your resume is the safer choice; if it needs work first, our guide on how to write a resume covers each section.

When does a letter of interest work?

It works best where hiring is informal and roles are rarely advertised, and least where an employer runs a set recruitment procedure. The table shows who is more likely to answer and where each point comes from.

How good are the odds? We found no reliable published rate: Prospects says an exact success rate is hard to give because speculative applications are not always tracked. You may read that 80% of jobs are never advertised, but we could not trace that number to a study, so we do not use it. Send a few well-researched messages, and keep applying to posted roles at the same time.

How do you write a letter of interest?

Research one employer, find a named person, write four short paragraphs and make one small request, then follow up once. The six steps:

1. Check the careers page first. If a role that fits is listed, apply to it with a regular cover letter. Prospects also tells readers to check that an employer is not advertising vacancies before researching it.
2. Pick 5 to 10 employers you would be glad to join. This number is our recommendation; a short list lets you research each one.
3. Find one real detail. Use a product, a recent project, a customer group or a stated value. Prospects also suggests reading any current vacancies, because a job specification shows which skills the business uses; our guide to tailoring your resume to a job description shows how to pick those skills out.
4. Find the right person. Write to the head of the team you want to join or to the hiring manager, not “Dear Sir or Madam”. Coursera suggests the company website, LinkedIn or a phone call to ask who to write to; see who to address a cover letter to.
5. Write a short letter or email. Use four parts: why this company, who you are with one or two results, a small request, and a close. Keep a letter to one page and an email to about 100 to 200 words (our recommendation; Coursera advises a single page). Draft it yourself or start from our free cover letter template (no AI), which runs in your browser.
6. Follow up once, then log it. Wait one to two weeks, send one short note, and record each letter in a free job application tracker template.

What should the small request be? CareerOneStop, sponsored by the U.S. Department of Labor, describes an informational interview as an informal conversation focused on learning, not on a job offer, and suggests 15 to 30 minutes. A short call is easier to agree to than a job.

Letter of interest example: what does a good one look like?

A good letter fits on one page and can be read in under a minute. The example below is complete, but the people, the company and the numbers are invented, so replace every detail. Use it when you send a formal letter, or an email with the letter attached, to a named manager.

Ms. Amara Okafor
Head of E-commerce
Northfield Outdoor Supply
[Company address]

Dear Ms. Okafor,

I am writing to ask whether your e-commerce team might have a place for an analyst like me, now or later. I noticed that Northfield added a second warehouse this spring and now promises two-day delivery, and I would like to help measure what that change does to repeat orders.

For the past three years I have been the only analyst at a regional home-goods retailer. I rebuilt its weekly sales report so buyers could see stock and margin in one view, which cut their reporting time from about six hours to two. I also ran the A/B tests behind a new checkout page that raised completed orders by 7%.

I would welcome 20 minutes to hear how your team uses its data and whether an analyst role is likely to open this year. My resume is attached, and I can send the report layout as a sample.

Thank you for your time. I will call your office next Thursday to ask whether you have a moment.

Sincerely,
Daniel Reyes

Word count: 173, from the greeting to the signature name. Why it works:

• It names a person and opens with something specific the company did.
• It gives two results with numbers instead of repeating the resume.
• It asks for 20 minutes, not a job, and says when the writer will call.

Letter of interest email example: what should it say?

A letter of interest often goes by email, and an email can be shorter than a letter. The invented example below uses the email body as the letter. Use it when you write to a manager or founder at a small company.

Subject: Packaging designer interested in work at Harbor Studio

Hello Mr. Lindqvist,

I'm a packaging designer with four years at a branding agency, and I've followed Harbor Studio's work for food brands since your refill-pouch project last year. I'm writing to ask whether you expect to add designers in the next few months.

At my agency I led the redesign of a 12-product snack line, which is now in 300 stores. The client's orders rose in the following quarter, and I can share the case study.

Could I send you my portfolio, or would 15 minutes by phone suit you better? I've attached a one-page resume. If now is a busy time, I'm glad to check back in the fall.

Thank you,
Priya Nair

Word count: 115, from the greeting to the signature name. It asks for a portfolio review or a short call, which is easier to say yes to than a job, and it offers a later check-in so a “not now” is not the end.

Is there a letter of interest template I can copy?

Yes. Fill in the brackets and cut anything that does not fit. Use it once you have done the research and know whom you are writing to.

Subject: [Your job title] interested in [Company name]

Dear [Name],

I'm a [job title] with [number] years of experience in [field]. I'm writing because [one specific thing about the company: a product, project or value], and I would like to help with [a specific need you can see].

At [current or recent employer], I [result with a number]. I also [second result or relevant skill].

Could we speak for [15 or 20] minutes about your team and whether a [job title] role is likely to open? I've attached my resume and can send [work sample] if it helps.

Thank you for your time. I'll follow up on [day] in case this one got buried.

Best regards,
[Name] | [phone] | [LinkedIn or portfolio link]

What subject lines work for a letter of interest email?

Name your role and your purpose in under ten words, and avoid vague lines such as “Job inquiry”. Prospects suggests a subject that makes your intentions clear, such as “Enthusiastic (your job title) interested in opportunities at (company name)”. Our guide to what to write in an email when sending a resume covers the rest of the message.

[Job title] interested in opportunities at [Company]
Exploring future [field] roles at [Company]
[Your name]: [job title] with [one result or credential]
[Mutual contact's name] suggested I write to you
Idea for [Company]'s [project], from a [job title]

Use the referral line only if it is true.

How do you end a letter of interest?

End with one small, specific request, say when you will follow up, and thank the reader in a single line. Coursera advises starting the call to action with a verb. Ask for a conversation rather than an interview, because there is no opening to interview for. Use the first closing when you plan to phone, the second for a softer ask, and the third when you expect a “not now”.

Could we speak for 15 minutes next week? I'll call on Thursday morning unless you suggest a better time.

I'd welcome the chance to learn how your team works and whether a suitable role may open. Thank you for your time.

If now is not the right moment, would you keep my resume on file and tell me who else I might contact?

What should you write in a follow-up email?

Follow up once, one to two weeks after the first message, with two or three lines that add something new. The University of Cincinnati suggests a polite email if there is no reply within two weeks. Prospects suggests a phone call after one to two weeks and warns that pestering does not show you in a good light.

Subject: Re: [Original subject line]

Hi [Name],

I wrote on [date] about [one-line recap] and wanted to check that it reached you. Since then I [one new thing: a finished project, a certification, a result], which relates to [their project or need].

If there is a better person to ask, I'd be grateful for a name. Either way, thank you for your time.

Best regards,
[Name]

If there is still no reply, log it and move on. Write again only if something changes, such as a new product or a hiring announcement.

How do you adapt a letter of interest for an internship, a teaching job or a career change?

Keep the same four parts and change the proof and the ask. Except where a source is named, the rows below are our recommendations.

Where can AI help with a letter of interest?

AI helps most before and after the writing: it can summarize company research, suggest tighter wording and cut a draft to length. It should not invent the company detail, the result or your reason for wanting the job.

• Research: paste a company’s about page or a recent news item into an assistant and ask for a summary, then check each claim yourself.
• Tailoring: give it your resume and research notes, ask for three opening lines, then rewrite one in your own voice.
• Cutting: ask for a version under 150 words that keeps your numbers.

The risk is a confident, wrong sentence about the employer. Our guides to the ChatGPT cover letter and the best AI cover letter generators cover prompts and options.

What mistakes sink a letter of interest?

Most failures come from sending a message that could have gone to anyone.

• A mass mailing. Send fewer messages and change the opening detail every time.
• “Any available position”. Name the kind of role you want. The Cambridge Careers Service advises saying clearly what you are looking for and being realistic in what you ask.
• A message about what you need. Prospects says the emphasis should be on what you can bring to the company, not on what it can do for you, so you don’t sound like you are begging for work.
• A repeated resume. The Cambridge Careers Service advises against repeating your CV or simply listing skills; offering to work on a short project can be more attractive.
• Chasing. Send one follow-up, not a series. A second or third reminder reads as pressure, not interest.

Does JobsAICopilot send letters of interest?

No. JobsAICopilot applies only to published listings on official company career pages. It does not send unsolicited applications, so a letter of interest is work you do yourself for the handful of employers you choose.
