Cover Letter vs Letter of Interest

A cover letter answers a question somebody asked. A letter of interest asks the question itself, which is a harder piece of writing and a genuinely different structure.

The structural difference

A cover letter has a posting to work with. The employer has stated what they want, in what order, in their own words. Your job is to answer requirement one with evidence, borrowing their vocabulary. Most of the framing is given to you.

A letter of interest has none of that. There is no posting, no stated priority, no vocabulary to borrow, and no established fact that they are hiring. You have to supply all of it, which means the letter has to do three things a cover letter never does:

• Identify a problem or opportunity the employer plausibly has.
• Propose something specific rather than offering yourself generally.
• Give them a low-cost next step, because there is no application process to point at.

That is why the two documents cannot share a template.

Why most speculative letters fail

They are cover letters with the posting removed.

I am writing to express my interest in any operations opportunities at Vance Logistics. I have six years of experience in warehouse management and would welcome the chance to discuss how I could contribute.

Nothing here is wrong. Nothing is actionable either. The recipient has no vacancy, no problem to attach you to, and no reason to do anything other than file it. “Any opportunities” gives them the work of finding one.

Purdue’s job search writing resources cover both letter types, and the recurring theme across them is specificity, which matters even more when there is no posting to be specific about.

The letter of interest that works

Dear Adaeze Nwankwo,

You opened the Boulder facility in March, which from the outside looks like it doubles your inbound volume on the same supplier base.

I ran the equivalent transition at Halvorsen Foods last year, taking us from 40 suppliers to 12 across eight months and through a second-site opening, with no stockouts. The part that mattered was sequencing: low-risk categories first, and overlapping suppliers kept running in parallel where a gap would have stopped a line.

I am not writing about a specific vacancy. I am moving to Denver in March and I would like fifteen minutes to hear how you are handling the supplier side, whether or not anything is open. If it is useful I will send the sequencing framework we used, which is a page.

Thank you for reading this far.

Why it works. It opens with something specific about them, observed rather than flattered. It supplies its own framing, so the reader knows why they are reading. It proposes fifteen minutes rather than a job, which is a request somebody can actually grant. And it offers something of value rather than only asking.

What it does not do. Ask for a job, list its skills, express enthusiasm, or say “any opportunities”.

The cover letter equivalent

Same person, same experience, responding to an actual posting.

Dear Hiring Team,

I am applying for the Operations Manager role at Vance Logistics. Your posting leads with consolidating suppliers after the acquisition, which is the project I spent most of last year on.

At Halvorsen Foods I took our supplier base from 40 to 12 across eight months without a stockout, keeping overlapping suppliers running in parallel on the categories where a gap would have stopped a line.

I have attached my resume and would welcome the chance to discuss the role.

Sincerely, Tomasz Wieczorek

Shorter, because the posting has done the framing. The evidence is the same; the surrounding work is not needed.

Who to send it to

The single biggest determinant of whether a speculative letter is read.

Send it to the person who owns the problem you are describing, usually the head of the relevant function. Not the general recruitment address, which is a process built around vacancies and has no mechanism for a letter about none.

Finding the name takes a few minutes: the company’s own team page, who posts about the function on professional networks, or a call to the main line asking who runs a given area. See how to address a cover letter.

The etiquette

Four rules that keep this from being spam.

One idea per letter, and make it about them. A letter that reads as researched gets a reply rate; a letter that reads as a mailshot does not.

Follow up once, after about ten days, briefly, then stop. A second follow-up converts a warm impression into an unwelcome one.

Do not attach a resume on the first contact unless you are asked, or attach it and keep the letter about the idea rather than the document. The letter is the pitch; the resume is what you send when they reply.

Send few, and make them good. Five researched letters outperform fifty generic ones by a wide margin, and take less time in total.

One caution on the other direction

If someone approaches you with an unsolicited job offer rather than the reverse, apply more scepticism than you would to a posting. Requests for payment, for identity documents, or for bank details early in a process are the pattern the FTC describes in its consumer guidance on job scams. A genuine employer does not need your bank details before an offer.

Which to write when

Cover letter: there is a posting. Answer it.

Letter of interest: you have a specific idea about a specific organisation, or you are relocating and building a network before you need one. Also the right instrument for approaching small employers who hire without advertising, which is a large share of the market.
