You’re scrolling through LinkedIn. You see a company that just looks cool. Maybe they’re doing groundbreaking work in sustainable tech, or maybe their brand voice is just exactly your vibe. But there is a problem. They aren't hiring. Or at least, they aren't hiring for what you do. Most people just close the tab and move on, but that is a massive mistake. Honestly, the letter of interest job application is the most underrated tool in your professional kit. It is basically the career equivalent of a "cold call," but way less annoying if you do it right.
Think about it.
When a job is posted on a public board, you’re competing with five hundred other people. You are a needle in a haystack. But when you send a letter of interest, you’re the only person in the room. You are creating a "hidden" opportunity. You’re telling a hiring manager, "I like what you do so much that I'm reaching out before you even asked." That kind of initiative is rare. Managers love it. It makes their lives easier because, eventually, they will need to hire, and your name will already be sitting in their inbox.
What a letter of interest job application actually is (and isn't)
People get these confused with cover letters all the time. They aren't the same. A cover letter is a response to an invitation; it's you saying, "I see you want X, and I have X." A letter of interest job application is proactive. It’s you saying, "I see what you’re building, and I have skills that can help you build it faster."
It’s more of an inquiry.
You aren't necessarily asking for a specific role with a specific ID number. You’re asking for a conversation. You’re pitching your value. According to career experts like Madeline Mann (the "Self Made Millennial"), the goal of this outreach isn't just to get a "yes" or "no" on a job—it's to build a relationship. You want to be top-of-mind. You want to be the person they call when the budget for a new head count finally gets approved next quarter.
It’s about timing. Sometimes you get lucky and hit them right when they’re drafting a job description but haven't posted it yet. In those cases, you’ve just saved the company thousands of dollars in recruiting fees. They will love you for that.

The anatomy of a letter that actually gets a response
Don't be boring. If you start with "To whom it may concern," you've already lost. Use a real name. Find the department head on LinkedIn or through the company’s "About Us" page. If you can’t find a name, you haven't looked hard enough. Honestly, the effort you put into finding the right person shows how much you actually care about the company.
Start with the why.
Why this company? Why now? Mention a recent project they finished or a specific value they hold that resonates with you. This isn't flattery. It's proof that you aren't just copy-pasting this to fifty different places. Then, pivot to your value. Don't just list your duties from your last job. Talk about results. Use numbers. If you increased sales by 20%, say that. If you streamlined a process that saved ten hours a week, mention it.
Keep it short.
People are busy. Your letter of interest job application should be punchy. Three paragraphs tops. Paragraph one: The hook (why them?). Paragraph two: The pitch (what you bring). Paragraph three: The ask (can we chat for fifteen minutes?). It is that simple.
Why "Wait and See" is a losing strategy
The job market is weird right now. It’s volatile. Companies are "quiet hiring" or relying heavily on internal referrals. If you only apply to active listings, you are only seeing about 20% of the actual opportunities out there. The other 80% is the "hidden job market."

The letter of interest job application is your key to that 80%.
I’ve seen people land roles that didn't even exist until they sent their letter. The manager read the letter, realized they had a gap in their team they hadn't fully articulated yet, and created a position specifically for that candidate. It happens more often than you’d think. Especially in startups and mid-sized firms where roles are fluid.
Common myths that stop people from reaching out
- Myth: I’m being annoying. Reality: You’re being a problem-solver. As long as you’re professional and your pitch is relevant, you’re providing value.
- Myth: They’ll just tell me to check the careers page.
Reality: Some will. That’s fine. But some will pass your resume to a recruiter with a note saying, "Keep an eye on this person." - Myth: I need a referral first.
Reality: Referrals help, but a strong cold letter can be just as effective if it’s personalized and high-impact.
Real-world examples of what to say
Let's look at how you might actually phrase this. You don't want to sound like a robot.
Imagine you’re a graphic designer reaching out to a boutique agency. You might say: "I’ve been following your work on the [Project Name] campaign, and the way you handled the typography was incredible. I’m a designer specializing in brand identity, and I’ve spent the last three years helping tech startups find their visual voice. I know you aren't actively listing a design role, but I’d love to show you how my background in motion graphics could complement your current team."
See how that works? It’s specific. It’s complimentary without being creepy. It offers a specific skill (motion graphics) that they might be missing.
For a more corporate setting, maybe a letter of interest job application for a project management role: "Your recent expansion into the European market is fascinating. Managing international logistics is a puzzle I’ve been solving for the last half-decade at [Previous Company], where I reduced shipping delays by 15%. I’m a huge fan of your operational efficiency and would love to discuss how my experience with cross-border regulations could support your growth."

It’s all about alignment.
The technical side: Subject lines and follow-ups
Your subject line is the most important part of the email. If they don't open it, the rest doesn't matter. Avoid "Job Inquiry." It’s boring. Try something like "Big fan of [Company] + [Your Area of Expertise]" or "Question about your [Specific Department] team." It needs to look like it’s coming from a human, not an automated system.
And follow up!
If you don't hear back in a week, send a polite nudge. "Hi [Name], just wanted to circle back on this. I’m still very interested in what you’re doing at [Company] and would love to connect if you have a moment." Sometimes emails just get buried. A single follow-up shows persistence. If they don't reply to the second one, let it go. Move on to the next lead.
Is it worth the effort?
Honestly, yeah. Even if it doesn't lead to a job today, you’re networking. You’re building a database of contacts. Recruiters move companies. Managers move companies. A person who couldn't hire you at Company A might move to Company B six months from now and remember that great letter you sent.
It's a long game.
Most people are too lazy to do this. They want the "Easy Apply" button. By putting in the work to craft a tailored letter of interest job application, you are instantly in the top 5% of candidates. You are showing that you are a self-starter. You’re showing that you do your research. You’re showing that you actually want to work there, specifically, not just anywhere.
Actionable steps for your outreach
- Identify 5 "Dream" Companies: Don't look at their job boards. Just list companies where you admire the culture or the product.
- Find the Gatekeeper: Use LinkedIn to find the Director or VP of the department you’d work in. Not the HR person—the person who would actually be your boss.
- Dig for a "Hook": Look for a recent news article, a blog post, or a LinkedIn update from the company. You need one specific thing to mention so they know you aren't a bot.
- Draft the Letter: Focus on one big win you’ve had in your career that relates to their current goals. Keep it under 200 words.
- Hit Send and Track: Use a simple spreadsheet to keep track of who you messaged and when. Set a reminder to follow up in 7 days.
- Optimize Your LinkedIn: Before you send anything, make sure your own profile is sharp. They will click on your name to see who you are.
- Be Patient: This is about planting seeds. Some will sprout tomorrow; some might take six months.
The best time to send a letter of interest was yesterday. The second best time is right now. Stop waiting for permission to apply and start making your own path. Good luck out there. It’s a bit of a jungle, but the people who take the lead are the ones who usually end up with the best views.
