You've found a company you'd love to work for. Maybe there's a job posted, maybe there isn't. You open a blank document and freeze, because now you're not sure what you're supposed to write. Is this a cover letter? A letter of interest? Does it even matter? When it comes to letter of interest vs cover letter, plenty of people use the terms as if they mean the same thing. They don't, and sending the wrong one can make your application feel slightly off.
The good news is that the difference is easy to understand once you see it laid out. In this post, I'll walk you through what separates the two, give you quick scenarios so you know which to pick, and show you an example of each side by side. By the end, you won't have to guess.
The One-Sentence Difference
Here's the simplest way to remember it:
A cover letter says, "Here's why I'm a good fit for this job you've advertised."
A letter of interest says, "Here's why I'd like to work for you, even though I haven't seen a specific job posted."
Everything else flows from that. One responds to a defined need. The other introduces you before the need is public.
Which One Should You Send? Real-Life Scenarios
Sometimes it's easier to decide by picturing your situation. Here are some common ones.
1. You see a job posting that fits you- Send a cover letter with your resume. It's expected, and it lets you connect your experience to the posted requirements.
2. You love a company but there are no openings- Send a letter of interest. You're introducing yourself and asking about future possibilities.
3. You're a student exploring entry-level options- If there's a posted internship or graduate role, send a cover letter. If you're just exploring organisations you admire, a letter of interest can open doors.
4. You met someone at a networking event- A short letter of interest (or a friendly email that works the same way) is a good follow-up, especially if they mentioned that opportunities might come up.
5. You're changing careers- Use a cover letter for advertised roles to explain how your experience transfers. Use a letter of interest to approach companies in your new field proactively.
6. A company says "send us your resume for future openings-" That's a letter of interest moment. Introduce yourself and say what kind of roles you'd like to be considered for.
7. You've been referred by a current employee- If there's a posted job, send a cover letter and mention the referral. If not, a letter of interest that names the referrer can be very effective.
Same Person, Two Letters
Let's see how the same applicant, a graphic designer named Nisha, might write each one.
The cover letter (for an advertised role)
Dear Mr. Rao,
I'm writing to apply for the Junior Graphic Designer position at [Company]. Your posting mentions experience with Adobe Illustrator and social media graphics, and that's exactly what I've been doing for the past two years as a freelance designer for local cafés and boutiques.
For one café, I created a series of weekly Instagram graphics that helped the owner see a noticeable rise in story replies and saved posts. I'd love to bring the same attention to detail and creativity to your design team.
I've attached my resume and portfolio, and I'd welcome the chance to discuss the role. Thank you for your time.
Sincerely, Nisha Verma
The letter of interest (no job posted)
Dear Mr. Rao,
I've followed [Company]'s design work for a while, and I especially admire the recent rebrand for [client or project]. I'm a freelance graphic designer with two years of experience creating social media graphics and branding for small businesses, and I'd love to explore whether there might be opportunities on your design team.
I enjoy turning rough ideas into clean, consistent visuals, and I'm keen to learn from a larger team. If any junior design roles open up, or if you'd be open to a short conversation, I'd be very grateful.
My resume and portfolio are attached. Thank you for your time and consideration.
Kind regards, Nisha Verma
Notice the differences: The cover letter refers to the posting and its requirements. The letter of interest refers to the company's work and asks for a conversation instead of an interview for a specific role.
How the Openings Differ
The first line often tells you which type of letter you're reading.
Cover letter opening: "I'm applying for the Marketing Assistant role listed on your website."
Letter of interest opening: "I've followed your recent campaigns for a while and would love to learn whether there might be a place for me on your marketing team."
Same person, same skills, but a different starting point.
What Each Letter Should Include
A good cover letter has:
The exact job title and company
Two or three skills or achievements matched to the posting
A specific reason you want this role
A polite request for an interview
A good letter of interest has:
A clear reason you're interested in this company
A short summary of your background and strengths
The kind of role or team you're hoping to join
A modest request, such as a brief chat or being considered for future openings
Can You Send Both?
Absolutely, just not at the same time. A common path looks like this:
You send a letter of interest while no roles are open.
A relevant job is posted a few months later.
You apply with a cover letter and resume, and mention your earlier message.
That sequence shows genuine, ongoing interest, which employers tend to appreciate.
Quick Decision Checklist
Ask yourself:
Is there a specific job posted that I want? Send a cover letter.
Am I introducing myself to a company with no relevant listing? Send a letter of interest.
Did the employer ask for a cover letter? Send one, always.
Am I following up after meeting someone? A short letter of interest or email works well.
Wrapping Up
The letter of interest vs cover letter question really comes down to one thing: is there a job posted or not? If yes, write a focused cover letter that matches the role. If no, write a warm, specific letter of interest that opens a conversation. Either way, keep it short, personal, and honest, and let your real strengths do the talking.
