How to ask for an introduction by email

Your connector is going to forward part of this email and delete the rest. The job is to make it obvious which part is which.

By Jerry Feng, Growth at Happenstance. Updated August 28, 2026.

The short version

Send one email with two halves. The top is five sentences to your connector: the name you want, why that person, and what you're asking for. Below a divider goes a paragraph about you written in the third person, so it can be forwarded without a single edit. Put the name in the subject line. Include one link and no attachment, and follow up once in the same thread.

Why the bottom half of the email does the work

An introduction request is really two emails in one. The top is a private note to somebody who knows you. The bottom is a paragraph for a stranger, and that is the part that gets forwarded. Most requests fail because they are written as one piece, which leaves the connector working out which sentences are for them and which a stranger is supposed to read.

Length matters more than style here. Boomerang's analysis of the email its users tracked found that “the sweet spot for email length is between 50-125 words, all of which yielded response rates above 50%” (2016). The same analysis found that subject lines of three or four words drew the most responses. Keep your note at the short end of that. The block underneath has a different reader, so it does not count against the note, which is why the whole email can be long and still feel quick.

There is a mechanical reason too. Forwarding means selecting text, or hitting forward and deleting half of it, usually on a phone and usually between two other things. A bio wrapped around an ask, a first-person paragraph they would have to rewrite, an attachment they have to re-attach: each one adds a delay, and delays turn into nevers.

Who to ask, how often, and what you owe them afterwards is a different question and it has its own page: how to ask for a warm introduction.

Doing this with Happenstance

Finding the connector is a search, not a memory test. Happenstance reads the accounts you connect, Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter and Instagram, and answers questions about your own network in plain English. Ask “Who do I know at Halyard, and how do I know them?” and the answer comes back ranked, with the evidence attached: years of email back and forth, a meeting on a calendar, an old shared employer, or nothing but a connection accepted once. That difference is the difference between an introduction that gets forwarded and one that gets a polite reply.

It also answers the version of the question you can't search your inbox for, “who do I know who knows Jordan Whitfield”, where the path runs through somebody you'd never have thought of. Groups and friends widen a search past your own accounts and into the networks of people you trust. Happenstance is free. The free plan is the whole product, with usage limits on chat and web searches beyond your network. Pro raises the limits: unlimited web searches and results, higher chat limits, and CSV export.

If you're writing this email to get into a company rather than a room, Happenstance for job seekers is the version of this aimed at hiring, and warm introductions covers how the paths are found.

Two versions of the same ask

One template is the full artifact, both halves, for a connector you email a few times a year. The other is what you send someone you are in a thread with every week, where a formal request would read as strange. Replace everything in brackets and keep the dashes.

Subject: Intro to [Jordan Whitfield] at [Halyard]?

[Ines], Are you close enough to [Jordan Whitfield] at [Halyard] to put my name in front of her? [She runs data engineering there, and the staff role on her team opened last week.] [You and I shipped the migration she wrote about in March.] I'm after a conversation, not a referral. Everything under the line is ready to forward as it is. [Your first name] ------------------------------------------ [Jordan], [Your name] spent four years on platform at [Corva], where [they rebuilt the deploy pipeline that took releases from forty minutes to six]. [They're looking at staff roles and would like twenty minutes on what your team is building.] [link to one page of their work] Copying [Your name] here.

The short version, for someone you already email weekly

Subject: [Jordan Whitfield] at [Halyard]

[Ines], are you close enough to [Jordan Whitfield] to send her my name? [Staff data role at Halyard, opened last week, and I have the migration story she would care about.] Say no if it's a stretch. If yes, I will send you a paragraph to forward this afternoon.

The short version deliberately holds the block back. Offering to send a paragraph is a smaller thing to say yes to than receiving one, and it gives you a second message in which to write the good version once you know they are in. A connector who replies asking whether they can put it to her first is running a double opt-in, which is the best reply this email can get. What they write next, once both sides are in, is the introduction email itself. If the only route you have to your connector runs through a platform, asking for an introduction on LinkedIn covers what that one can and can't do.

What Happenstance can see

Email is read as headers only. Message content and attachments never reach our servers. Yes. Your connections are searchable only by you, the friends you accept, and the groups you join, and sharing is always mutual. Your public profile shows a constellation of named people you know by default, which you can turn off anytime. We never share, sell, or use your data to train AI models. Happenstance is SOC 2 certified and DTI Trust Level 2; the full list of what is stored and for how long is on the security page.

Frequently asked questions

What should the subject line say when you ask for an introduction?

The name of the person you want, and little else. "Intro to Jordan Whitfield?" can be answered yes or no from a notification preview, which is the point. Subject lines like "quick question" or "catching up" hide the ask, and a hidden ask gets read later rather than answered now.

Where do you put the forwardable paragraph in the email?

Underneath your note, below a visible divider, with one line telling your connector that what's under it is theirs to send. Keeping the halves apart is what lets someone forward you in ten seconds. Pasted into the middle of the note, the same paragraph becomes something they have to reassemble first.

Should the forwardable paragraph be in the first person or the third?

Third person. Your connector is the one sending it, so it has to read as something they could plausibly have written about you. A paragraph in the first person forces a rewrite before it can go anywhere, and the rewrite is where most introduction requests stop.

Is it better to ask for an introduction by email or on LinkedIn?

Email, when the introduction matters. An email can be forwarded, it arrives where the other person already works, and it carries a paragraph of any length. LinkedIn is better for finding out who your connector knows than for carrying the request itself, which is covered on how to ask for an introduction on LinkedIn.

What do I do if my connector says yes and then nothing happens?

Reply in the same thread about a week later and paste the forwardable paragraph again, so the thing they need is in the newest message rather than three scrolls up. Say once that there's no pressure, then leave it. People who meant to forward it usually do so within a day of seeing it again.

Should I email a connector at their work address or their personal one?

Whichever address you've exchanged mail at before. A message that lands in a thread you two already have gets opened; the same message to an address with no history sits with everything else. If you only have a work address at a company they've left, that is a sign to pick a different connector.
