Making a great email introduction is one of the most underrated professional skills. It costs you nothing but five minutes. And it can create real value for two people you care about.
But bad introductions? They waste everyone's time and make you look thoughtless.
The difference between a good intro and a bad one comes down to a few simple rules.
Always Ask Permission First
This is rule number one and it's non-negotiable. Never introduce two people without asking both of them first.
It's called a "double opt-in" introduction, and it exists for a good reason. You don't know what's going on in someone's life. They might be swamped. They might already know the other person. They might have a complicated history with them. Or they might just not be interested.
Sending an unsolicited introduction puts both people in an awkward position. They feel obligated to respond even if they don't want to.
Here's what the permission ask looks like:
Hi [Person A],
>
I know someone I think you should meet. [Person B] is a [what they do] who's working on [relevant project]. I think you two would hit it off because [specific reason].
>
Would you be open to an intro?
Wait for the yes before you connect them. If they say no or don't respond, respect that. Don't push.
The Introduction Email Format
Once both people have said yes, send the introduction. The format is simple but specific. Every good intro email has three parts.
Part 1: Why Person A should care about Person B.
Part 2: Why Person B should care about Person A.
Part 3: A suggested next step.
Here's the template:
Subject: Intro: [Person A] <> [Person B]
>
Hi [Person A] and [Person B],
>
I wanted to connect you two.
>
[Person A], meet [Person B]. [Person B] is [their role] at [company/freelance context]. They're doing interesting work in [specific area], and I thought you'd find their perspective on [topic] really valuable.
>
[Person B], meet [Person A]. [Person A] is [their role] at [company/freelance context]. They've been working on [specific thing] and I think your experience with [overlapping area] would be really useful for them.
>
I'll let you two take it from here. I think a quick call or coffee would be well worth it.
>
Best,
[Your name]
Then get out of the way. Move yourself to BCC after the intro so you don't clog up their reply chain. Some people do this automatically in the intro email by saying "moving myself to BCC."
What Makes an Introduction Actually Useful
The best introductions aren't just "you two should meet." They're specific about why.
Generic: "You're both in marketing, so I thought you should connect."
Specific: "You're both focused on email marketing for SaaS companies, and you were just telling me about your challenge with onboarding sequences, which is exactly what Sarah has been crushing for the last two years."
The specificity does two things. It gives both people a reason to say yes to the meeting. And it gives them something to talk about when they do meet. You're not just connecting people. You're starting a conversation.
Templates for Different Situations
Introducing a Potential Client to a Service Provider
Subject: Intro: [Client name] <> [Provider name]
>
Hi both,
>
[Client name], I wanted to connect you with [Provider name]. They specialize in [service] and have done great work for companies like [examples]. Given what you told me about [client's challenge], I think they could really help.
>
[Provider name], [Client name] runs [their business/role] and is looking for help with [specific need]. I think this is right in your wheelhouse.
>
I'll let you two figure out timing for a chat.
>
Best,
[Your name]
Introducing Two Peers Who Should Know Each Other
Subject: Intro: [Name] <> [Name]
>
Hi [Name] and [Name],
>
I've been meaning to connect you two for a while. You're both doing really interesting work in [shared field], and I think you'd get a lot out of knowing each other.
>
[Name], [Name] recently [specific accomplishment or project]. [Name], [Name] has been [specific accomplishment or project].
>
Would love for you two to connect. A quick coffee or call would be great.
>
[Your name]
Introducing Someone Who's Looking for a Job
This one requires extra care. The person looking for a job might feel vulnerable, so frame it in terms of their strengths, not their needs.
Subject: Intro: [Job seeker] <> [Contact]
>
Hi both,
>
[Contact], I wanted to introduce you to [Job seeker]. They're a [role] with deep experience in [specific skills]. They recently [accomplishment] and they're exploring new opportunities.
>
[Job seeker], [Contact] leads [team/department] at [company] and has a great eye for talent. I thought you two should be in touch.
>
I'll let you take it from here.
>
[Your name]
Notice how the email doesn't say "they need a job." It positions them as a talented professional exploring options. That framing matters.
Common Mistakes in Email Introductions
No context. "You two should meet!" doesn't give anyone a reason to follow up. Always explain why.
Too much context. A five-paragraph essay about each person is overkill. Keep it to two or three sentences per person.
Making it about you. The introduction isn't about how great you are for knowing both these people. Keep the focus on them.
Not following up. If you make an intro and neither person responds, check in with them individually. Sometimes emails get buried.
Introducing without permission. I already said this but it's the most common mistake, so it bears repeating.
One-sided intros. If you only explain why Person A is great and don't give Person B any context, the intro feels unbalanced. Both people need to understand why the connection is worth their time.
What to Do After the Introduction
Your job is mostly done after you send the email. But there are a few things that separate a good connector from a great one.
Follow up after a week. Send a quick note to one or both people asking if they connected. This shows you actually care about the outcome, not just the introduction itself.
Track your intros. Keep a simple list of who you've introduced and when. It helps you avoid making duplicate introductions and lets you follow up at the right time.
Close the loop. If someone thanks you for an intro that went well, great. Make a mental note. That person is someone you can introduce to others in the future.

Building a Reputation as a Great Connector
People who make great introductions build a specific kind of reputation. They become the person others go to when they need to find someone. And that's an incredibly valuable position to be in.
The key is quality over quantity. Don't make introductions just to make them. Only connect people when you genuinely think both parties will benefit. A few excellent introductions are worth more than dozens of random ones.
Think about it from both sides before you offer. Would Person A actually want to meet Person B? Would Person B actually benefit from knowing Person A? If either answer is no, or even maybe, skip it.
When you get this right consistently, something interesting happens. People start making great introductions back to you. They send clients your way. They connect you with opportunities. Because that's how networks work. Generosity compounds.
Start with one introduction this week. Think of two people in your network who would genuinely benefit from knowing each other. Ask both for permission. Send the email. It'll take you ten minutes, and the impact could be enormous.
