What is a double opt-in introduction?
Definition: A double opt-in introduction is an introduction where the connector asks each person privately for permission before connecting them, and only sends the joint introduction once both have agreed. It protects everyone's time and inbox, gives either side an easy way to decline, and makes the eventual introduction warmer because both people already know why they are meeting and want to talk.

Why it matters
Every introduction you make spends a little of your credibility. If you push a stranger into someone's inbox without asking, you are making a decision about their time for them. Asking first shows respect, and people remember who respects their time. That memory is what keeps them saying yes to you later.
It also makes your introductions work better. When both people have already agreed, the first reply comes fast and the conversation starts with real interest. A quiet no in private is far kinder than an awkward silence in a group thread, and it keeps every relationship involved intact.
How it works
Step one: the private ask
You start by writing to the person who will be asked for something, usually the more senior or busier one. Explain who the other person is, why you think they should talk, and what the other person hopes to get from it. Keep it short and specific. Then make it clearly optional: something like "No pressure at all, just let me know if you are open to it." Many connectors also check with the requester first to confirm they still want the introduction and to get a short blurb about themselves you can forward.
Step two: the yes, or the graceful no
Wait for a clear answer. If the person says yes, you move on to the joint email. If they decline or never reply, you simply tell the requester it is not a fit right now, without blaming anyone. No one is embarrassed, because the declined introduction never happened in public. Give it about a week before treating silence as a no. A gentle nudge is fine once, but more than that turns a favor into pressure, which defeats the purpose.
Step three: the joint introduction
Once both have agreed, send one email to both people. Name each person, give one or two lines on who they are, and say plainly why you are connecting them. Mention that both already said they would like to talk, so neither feels ambushed. Suggest a next step, such as a short call. Then step back. A common courtesy is for the person who asked for the introduction to reply first and move the connector to BCC, which keeps your inbox clear.
How it differs from a single opt-in introduction
In a single opt-in introduction, the connector sends the joint email without asking either person first, or after asking only the requester. It is faster, and it can be fine between peers who you know will welcome the contact. The risk is that the receiver feels obligated, cornered or annoyed. The double opt-in version adds one extra message, but it moves the decision back to the people whose time is being spent, which is why it has become the standard for busy professionals.
Examples
- A consultant wants to meet a CFO you know. You email the CFO alone, describe the consultant's work in two sentences, and ask if she is open to a 20 minute call before you connect them.
- A former colleague is job hunting and asks for an intro to a hiring manager in your network. You first ask the hiring manager whether he wants to hear from a strong operations candidate, then send the joint email only after he says yes.
- A founder asks to meet an investor you have known for years. The investor replies that the timing is wrong, so you tell the founder kindly that it is not a fit right now, and no awkward thread ever exists.
- Two board members at a nonprofit could help each other with fundraising. You message each one separately, both say yes, and your joint email opens with "You both told me you would like to compare notes."
Putting it into practice
- Ask the requester for a short, forwardable blurb: who they are, what they want, and why this specific person.
- Send the private permission email to the receiver first, and make declining easy and guilt free.
- Wait about a week for a reply, nudge once if needed, and treat continued silence as a polite no.
- When both agree, send one short joint email that names the reason for the connection and suggests a next step.
- Ask the requester to reply first and move you to BCC, then check in with both a few weeks later to see if it helped.
- Keep a simple note of introductions you have made and how they turned out, so you know who welcomes them and who is at capacity.

Frequently asked questions
How do you write an email introducing two people to each other?
Write one short email to both people that names each person, gives one or two lines on who they are, and states clearly why they should talk. In a double opt-in introduction, mention that both already agreed to connect. Suggest a concrete next step, like a short call, then step back and let the requester reply first and move you to BCC.
What is single opt-in and double opt-in?
Single opt-in means only one confirmation is needed before action is taken, while double opt-in requires a second, explicit yes. For introductions, single opt-in means the connector sends the joint email without asking the receiver first. Double opt-in means both people agree privately before the introduction goes out. In email marketing, the terms describe whether new subscribers must confirm their sign-up.
Who should you ask first in a double opt-in introduction?
Ask the person being asked for something first, usually the busier or more senior one. The requester already wants the meeting, so their yes is mostly assumed, though it helps to confirm they still want it and get a short blurb from them. Asking the receiver first protects them from feeling cornered and lets them decline privately.
What should you do if someone says no to an introduction?
Thank them, accept it without pushing, and tell the requester it is not a fit right now. Do not share the receiver's reasons or make it sound personal. A graceful no is the whole point of the double opt-in approach, and handling it well makes both people more likely to trust your future introductions.
Is a double opt-in introduction always necessary?
No, but it is the safer default. Between close peers who you know will welcome the contact, a direct introduction can be fine. When the receiver is busy, senior, in high demand, or doesn't know you well, ask first. If you are unsure whether someone would want the introduction, that uncertainty is your answer: ask.
Both said yes. Will you know how it went? Log the intro on both timelines in Capstone, with a note on why you connected them. A few weeks later, you can check in with each one and ask how it went.
