How to Thank Someone for an Introduction

By Shawn Gregoire, founder of Capstone Outreach · Updated October 2026

To thank someone for an introduction by email, reply within a day and thank the connector by name. Move them to BCC to keep their inbox clear. Take the next step with the new contact in the same message. Later, close the loop by telling the connector how the talk went. That second note makes people want to introduce you again.

A warm introduction is a favor that costs the connector some of their own credibility. They vouched for you. How fast and gracefully you respond tells them if it was worth it. It also tells them whether to do it again.

Most people handle the first reply fine and forget the rest. The thank-you that lands comes back weeks later with an update: we met, here's what came of it, thank you again. Connectors rarely hear what happened. So the people who tell them stand out.

1. Reply-all to the introduction, connector to BCC (email)

Subject: Re: Introduction: [Your name] / [New contact]

Thanks so much, [Connector], for connecting us. (Moving you to BCC to spare your inbox.) [New contact], it's great to meet you. [Connector] has told me about [specific detail, e.g. the community lending program you launched last year], and I'd love to hear more about how it's going. Would a 20-minute call work next week? I'm free [day/time] or [day/time], or feel free to send a time that suits you better. Best, [Your name]

Why it works: Thanking the connector, clearing their inbox and offering set times handles it all in one short reply.

2. Private thank-you to the connector right after the intro (email)

Subject: Thank you for the introduction

Hi [Connector], Thank you for introducing me to [New contact]. I know you don't make introductions lightly, and I appreciate you putting your name behind it. I've replied and suggested a call for next week. I'll make sure to respect their time and I'll let you know how it goes. If there's ever someone I can introduce you to, just ask. [Your name]

Why it works: Naming the trust and offering to return the favor makes the exchange feel mutual.

3. Update to the connector after your first meeting (email)

Subject: Update: I met with [New contact]

Hi [Connector], Quick update: [New contact] and I talked on [day]. You were right, [specific detail, e.g. we approach donor retention almost the same way]. We're going to [next step, e.g. compare notes on our spring campaigns next month]. Thank you again for thinking of us together. It was a genuinely useful conversation. [Your name]

Why it works: Hearing their instinct was right is the most satisfying news a connector can get about an intro.

4. Outcome thank-you after the intro led to a client or deal (email)

Subject: Your introduction turned into something

Hi [Connector], I wanted you to hear this from me: [New contact] signed on as a client this week. It all started with your introduction in [month]. That's a big deal for [Your Company], and it wouldn't have happened without you vouching for us. Thank you. I'd love to take you to lunch to say thanks properly. Are you free in the next few weeks? [Your name]

Why it works: Crediting the connector for a real result is the strongest thanks you can give, and lunch makes it real.

5. Job seeker thanking someone for an intro to a hiring manager (email)

Subject: Thank you for the introduction to [New contact]

Hi [Connector], Thank you so much for introducing me to [New contact] at [Company]. I know how busy you are, and I'm grateful you took the time. We've set up a conversation for [day]. I've read up on [specific detail, e.g. their team's move into healthcare clients] so I can make the most of it. Whatever comes of it, I really appreciate your help. I'll keep you posted. [Your name]

Why it works: Showing you've prepared tells the connector their intro won't reflect badly on them.

6. Founder thanking someone for an investor introduction (email)

Subject: Thank you for the intro to [Investor]

Hi [Connector], Thank you for the introduction to [Investor]. A warm intro from you carries real weight, and I don't take that for granted. We have a first call on [date]. I'll keep it focused on [specific detail, e.g. our pilot results with the two hospital systems], since you mentioned that's what she cares about. I'll let you know how it goes, either way. [Your name]

Why it works: Using the connector's advice in your prep shows you listened and protects their tie with the investor.

7. Replying to someone who introduced themselves to you (email)

Subject: Re: [their subject]

Hi [Name], Thank you for your email and the introduction. It's good to meet you, and I appreciated the context about [specific detail from their email, e.g. your work with first-time homebuyers]. I'd be glad to talk. I'm free [day/time] or [day/time] for a short call. If neither works, send a couple of times that do. Looking forward to it, [Your name]

Why it works: Naming a detail from their message shows you read it and makes the reply feel personal, not automatic.

8. When the introduction didn't lead anywhere (email)

Subject: Thank you again for connecting me with [New contact]

Hi [Connector], I wanted to close the loop. [New contact] and I had a good conversation, but the timing isn't right for [specific reason, e.g. a partnership this year]. We agreed to stay in touch. I still learned a lot from talking with [him or her], especially about [specific detail]. Thank you for making the connection. It was worth it. [Your name]

Why it works: Reporting a neutral outcome honestly still respects the connector's effort and keeps them willing to help again.

9. Thanking a connector for a double opt-in introduction (email)

Subject: Yes, and thank you

Hi [Connector], Thank you for checking with me first. Yes, I'd love an introduction to [New contact]. I've followed [his or her] work on [specific detail] for a while. If it helps, here's a short line you can pass along: [one-sentence description of who you are and why you'd like to talk]. Thanks for making this easy. [Your name]

Why it works: A ready-made blurb saves the connector time and makes the intro more likely to happen.

10. Long-delayed thank-you when an intro paid off much later (email)

Subject: A thank-you a year in the making

Hi [Connector], You probably don't remember, but last [season or year] you introduced me to [New contact]. That one email turned into [specific outcome, e.g. a board seat and two of my best clients]. I realized I never told you how much it mattered. So: thank you. Introductions like yours are the reason I try to make them for others. Hope all is well with you. [Your name]

Why it works: Thanks for a long-forgotten favor is a happy surprise that strengthens the relationship years later.

When to send it

Subject lines

What to avoid

After you send it

If the new contact hasn't replied in four or five business days, send one short nudge. Use the same thread, with the connector still in BCC. Update the connector within a week of meeting, and again if anything concrete comes of it. Then keep the connector relationship warm on its own. Check in every few months, share a useful article, and make an intro of your own when you can. Good connectors notice who returns the favor.

Building the habit: how to keep in touch with contacts and what a personal CRM does.

Close the loop with the person who introduced you They want to hear how it went. Capstone saves where you met each new contact and who made the intro. So the update a month from now is easy to write.

A study of 20 million LinkedIn members found that acquaintances, more than close friends, led to new jobs (Science, 2022). Capstone keeps those people warm. You approve every message, and it goes from your own email or phone.

Frequently asked questions

How do you thank someone for an introduction?

Reply to the intro within a day, thank the connector by name, and move them to BCC. Set up the next step with the new contact. Then send the connector a short update after you meet. Send a final thank-you if anything comes of it. That follow-through matters more than the first reply.

How do you say thank you for the introduction via email?

Start your reply with a direct line to the connector: 'Thanks so much, [Name], for connecting us. Moving you to BCC to spare your inbox.' Then turn to the new contact and say why you're glad to meet them. Propose two specific times to talk. Keep the whole reply under a hundred words.

Should I move the person who introduced us to BCC?

Yes. Moving the connector to BCC in your first reply is standard etiquette. It lets them see that you replied without getting every scheduling email after. Say so in the message, like '(moving [Name] to BCC)'. Then the new contact knows to reply only to you.

How do you reply to an introduction email from the person being introduced?

Thank them for reaching out. Mention one specific detail from their message so they know you read it. Then propose a next step with specific times. If a connector introduced you both, thank the connector in the first line and move them to BCC. Keep it short and warm.

Should you update the person who made the introduction?

Yes, always. Send a short update within a week of meeting, and another if something concrete happens. Connectors rarely hear how their intros turned out. A simple 'we met, here's what came of it, thank you' stands out. It makes them far more likely to introduce you again.
