Most referrals start with a short email, and most short emails that work follow the same pattern. A letter of introduction for a job names a shared connection in the first sentence, says who you are in one line, offers a single piece of proof, and asks for something small, usually a short call. It is how job seekers reach a hiring manager who would never open a cold application.

There are two of these letters, and almost every guide shows only one. You write the first kind yourself, to a person a mutual contact pointed you toward. A contact writes the second kind for you, putting you and someone they know in the same email thread. This page covers both, along with the piece that makes the second one happen, the short blurb you hand your introducer so they can forward it without writing a word themselves.

Here is the scenario behind the example below. Nadia Brooks has spent four years as a UX researcher at a health-tech startup. Her former professor, Dr. Alan Pierce, mentioned that a research director at a regional hospital system is building out a patient-experience team, and he suggested she write. Nadia has never met the director.

Three choices make her letter work. Pierce's name sits in the first sentence, because his name is the only reason a stranger keeps reading. One proof line carries her credibility, a usability study that cut patient portal sign-up drop-off from 40% to 22%, and she resists the urge to add two more. And the ask is a 20-minute call, something a busy director can say yes to without checking headcount or talking to HR.

Notice what the letter refuses to do. No resume walk-through, no list of research methods she knows, no hint that she expects a job to materialize. The whole document exists to make one small yes easy. If the call happens, her resume and portfolio get their turn; sending them now would turn a warm note into an application the director never asked for.

The time frame on the ask matters more than people think. "A 20-minute call in the next two weeks" gives the reader a box to put you in. An open-ended "I'd love to connect sometime" gives them nothing to schedule and usually gets nothing back.

The second letter is shorter, and you don't write it. Nadia's former manager, Grace Liu, knows Omar Haddad, a design lead at a fictional insurance company that is investing in research. Grace asked Omar first whether he'd take an introduction, and he said yes. Only then did she send the email. That double opt-in is the etiquette that separates a welcome introduction from an ambush, and skipping it burns the introducer's credibility rather than yours.

Grace's email runs five lines, and each line has exactly one job.

If you are the person being introduced, reply fast. Within a day, thank the introducer briefly, move them to BCC so the thread stops filling their inbox, and make the same small ask from letter one. Their reputation rides on you following through, which is why slow replies quietly end future introductions.

Introductions die of friction. Grace wants to help, but writing two accurate sentences about Nadia's work takes effort she will put off for a week and then forget. So Nadia removes the writing. When she asks for the introduction, she includes a short blurb, about 80 words, written in third person so Grace can paste it into her email untouched.

The blurb carries four things. One line on who Nadia is and where she has worked. One line on what she is exploring, research roles in insurance and health systems. Then the same proof line from her letter, the drop-off number, and finally the ask, a short call to compare notes on how Omar's team runs research.

The message that carries the blurb is two lines on its own. The first asks the favor plainly, "Would you be open to introducing me to Omar Haddad at Meridian Insurance?" The second removes the work, "I've put a short blurb below that you can forward as is, and no pressure at all if the timing is wrong." An introducer who can say yes in ten seconds usually does.

A letter of introduction for a job is a short letter or email, usually under 200 words, that introduces you, or someone you vouch for, to a person who can help with a job search. It almost always travels through a shared connection, and it asks for something small, a conversation or advice, rather than a job or an interview. Think of it as the written version of "you two should talk."

It is not a cover letter wearing a different name. A cover letter answers a specific posting and asks for an interview. A letter of introduction opens a relationship before any posting exists, which is exactly why it works: you reach the hiring manager while the generic applicants are still waiting for a job ad to appear.

One wrinkle trips people up. Some applications, especially for teaching jobs, ask for a "letter of introduction" as part of the packet. That is not a networking note; districts use the phrase to mean a cover letter for that posting that opens with who you are. Write it as you would any strong cover letter, lead with your certification and the grade levels you've taught, and don't send them a request for a 20-minute call. The teacher cover letter examples show that structure in full.

Never open with "My name is." Your name is in the signature and the email address; spending the first sentence on it wastes the only line a busy reader is guaranteed to see. Open with the connection or the reason instead, and let your name arrive on its own.

The pattern holds across all seven. Connection or reason first, you second, and a specific detail that proves the line was written for this person. If an opener would survive a find-and-replace on the recipient's name, it isn't done yet.

A letter of introduction earns a reply by being easy to act on. Six elements belong in it, and everything else is weight.

Leave out the rest. Your full work history belongs in the call, if it comes up at all. A skills inventory reads like an application, which is the one thing this letter must not resemble. Unrequested attachments trip spam filters and signal that you skipped the "small ask" part. And "are you hiring?" converts a warm note into a cold query the reader can answer with one word, usually no.

Email is the default. A mailed letter is a curiosity in most industries now, and LinkedIn messages get buried; an email with a clear subject line gets read, or at least triaged. For the self-introduction, put the connection in the subject, "Alan Pierce suggested I reach out." When someone introduces you, the subject follows the pattern from example two, both names after the word "Introduction."

Silence is normal and usually means busy, so follow up exactly once, about a week later. Keep it to two sentences and restate the small ask, with no guilt attached. A second nudge starts to cost you goodwill; let it go and spend the energy on the next introduction. The same discipline applies to applications, and the templates in how to follow up on a job application transfer directly.

Close the loop with your introducer no matter what happened. A two-line note, "Omar and I spoke Tuesday, hugely helpful, thank you again," tells Grace her introduction landed and makes her glad to write the next one. An introducer who hears nothing assumes the worst and quietly stops introducing.

Students run the same play through the alumni network, with the shared school standing in for the mutual contact. Nadia's opening paragraph, rewritten for a senior writing to an alum, looks like this: "As a current Michigan senior studying cognitive science, I found your profile through the alumni directory and saw you moved from our HCI program into health-tech research. I'm trying to understand what that path looks like in practice, and I'd be grateful for 15 minutes of your time before the semester ends." The proof line can be a class project or an internship result; the mechanics don't change.

A good intro call often surfaces an actual role, sometimes one that isn't posted yet. At that point the letter of introduction has done its job, and the application deserves a real cover letter aimed at that specific opening. The Roleframe cover letter builder drafts one from your resume for you to edit, with the document open beside it so the two never contradict each other.

Track the people, too. Add both your introducer and the new contact to the contact tracker, tagged and linked to the job they led to. Six weeks into a search with 40 applications, "who opened this door" is a question you will otherwise answer from memory, badly.
