Double opt-in introductions
The short answer
A double opt-in introduction is one where the introducer asks each person separately whether they want to be connected, and only introduces them when both say yes. It protects everyone's time, lets people decline privately, and makes the meeting that follows far more likely to go well.
Most people have received a blind introduction: an email out of nowhere that says "You two should meet!" and copies in a stranger. Sometimes it's great. Often it's a meeting you didn't want and now feel obliged to take, or have to decline in front of the person who introduced you.
A double opt-in introduction fixes this with one extra step. Before connecting two people, the introducer checks with each of them privately. If both want to meet, they make the introduction. If either doesn't, nobody is embarrassed and no time is wasted.
Why it matters
- It respects time. Senior people get many introduction requests. Checking first lets them choose the ones that matter to them.
- It allows a quiet no. Declining privately to a friend is easy. Declining in a group email is awkward, so people accept meetings they don't want and turn up half-engaged.
- It protects the introducer's reputation. Every introduction spends a little of the introducer's credibility. Checking first means they only spend it on introductions both sides value.
- It makes better meetings. When both people have said yes, they arrive knowing why they're meeting and wanting to be there.
How to make a double opt-in introduction
Step 1: Get the context from the person asking
If someone asks you for an introduction, ask them for a short forwardable note first: who they are, why this person, and what they want. If they haven't written one, it's fine to ask. The forwardable intro email guide shows what a good one looks like.
Step 2: Ask the other person privately
Forward the note to the person being asked to meet, with a line about why you think it's worth their time, and an explicit easy out.
Hi Jordan, A friend of mine, Sam Rivera, would love 20 minutes with you. Their note is below. I've known Sam for five years and think you'd enjoy comparing notes on scaling support teams. Would you be open to an introduction? Completely fine to say no, I won't pass anything on unless you're keen. Alex
Step 3: Introduce them, or close the loop
If they say yes, make a short introduction that gives each person a reason to reply. If they say no, or don't reply within a week, tell the person who asked, kindly and without detail.
Jordan, meet Sam. Sam runs customer operations at Brightline and is about to double their support team. Sam, meet Jordan. Jordan built the support team at Northwind from 8 people to 70. I'll leave you two to find a time. Enjoy the chat! Alex
Hi Sam, I checked with Jordan, and the timing isn't right for them at the moment. Sorry I couldn't make this one happen. Happy to think about who else might be helpful.
When you're the one asking
You can make double opt-in the default even when you're asking for the introduction. Tell your introducer you'd be grateful if they checked with the other person first. It takes pressure off them and signals that you respect the other person's time. See how to ask for a warm introduction.
When a single opt-in is fine
Double opt-in is the respectful default, not a rule for every situation. You can reasonably skip the check when:
- Both people have told you they want to meet people like each other.
- You're introducing two peers at a similar stage who would clearly both benefit, and neither is overloaded with requests.
- The other person has publicly asked for exactly this kind of introduction, such as a post asking for help with a specific problem.
When in doubt, check. It costs a day. A blind introduction someone didn't want costs goodwill.
Double opt-in in communities
In professional communities, double opt-in is what makes members comfortable being introduced at all. When members know they'll always be asked first, they're more willing to share what they're working on, and more introductions happen overall.
Frequently asked questions
What does double opt-in introduction mean?
The introducer asks both people, separately and privately, whether they want to be introduced, and only connects them if both agree.
Is it rude to make an introduction without asking first?
Not always, but it can put people in an awkward spot. Checking first is the safer default, especially for busy or senior people who receive many requests.
How long should I wait for a reply before closing the loop?
About a week. If there's no reply, let the person who asked know that it isn't going to happen this time, without making it sound like a rejection.
What's the difference between a warm introduction and a double opt-in introduction?
A warm introduction is any introduction made by someone who knows both people. A double opt-in introduction is a warm introduction where both people agreed before being connected.
