# Double opt-in introduction email template set

> A double opt-in introduction email asks one person privately whether they want to be introduced, before you share anyone's details. You send it to the person who might help, confirm with the person who asked, and connect them only when both say yes. The set has four emails: the ask, the check, the introduction itself and a kind reply when the answer is no.

## Key takeaways

- Ask the person who can help first. They are the one doing a favour.
- Describe the need without sharing the other person's contact details.
- Make no an easy answer, with a reply that needs one or two words.
- If someone declines, never tell the other person who it was.

## How a double opt-in introduction email works

1. Someone asks you for an introduction, or you spot a good match.
2. You email the person who could help, describing the need, and ask if they are open to it.
3. You confirm with the person who asked that they still want it and are happy for their details to be shared.
4. When both say yes, you send one short email connecting them.
5. If either says no, you close the loop politely and share nothing.

## Email 1: ask the person who could help

Opt-in request:

```text
Subject: Would you like an introduction to [Name A]?

Hi [Name B],

[Name A], who is part of [community], is looking for [need] in [city], ideally by [timing]. I thought of you because [specific reason].

Would you be open to an introduction? If yes, I'll send you both one email with each other's details. If not, just reply "not now" and I won't share anything.

[Optional: [Name A]'s website, so you can decide: [link]]

Thanks,
[Your name]
```

## Email 2: check with the person who asked

Requester check:

```text
Subject: Re: your request for [need]

Hi [Name A],

I may have someone for you: [Name B], who [one line on what they do]. Before I connect you, two quick checks:

1. Do you still need help with [need]?
2. Are you happy for me to share your email with [Name B]?

Reply yes and I'll introduce you both.

[Your name]
```

## Email 3: the introduction after both say yes

Both people have agreed, so this one can be brief. For fuller wording and WhatsApp versions, see the [warm introduction message templates](https://milvao.com/templates/introduction-message-template).

Introduction:

```text
Subject: [Name A], meet [Name B]

Hi both,

Thanks for agreeing to connect. [Name A] needs [need] by [timing]; [Name B] [relevant experience].

[Name A], over to you to suggest a time. I'll drop off the thread.

[Your name]
```

## Email 4: when the answer is no

Reply after a decline:

```text
Subject: Re: your request for [need]

Hi [Name A],

A quick update: the person I had in mind can't take this on right now. I'll keep looking and come back to you if someone else fits.

If anything about the request has changed, let me know.

[Your name]
```

Send this whether the person declined or simply didn't reply after a few days. It protects their privacy and keeps the requester from waiting.

## Mistakes that undo the opt-in

- Copying both people on the first email. That is a regular introduction with a question attached.
- Naming the requester's company or budget when the person being asked doesn't need it to decide.
- Chasing a no. One reminder is plenty; silence is an answer.
- Subject lines like "Quick favour" that hide what the email is about.

## The same flow on WhatsApp with Milvao

Milvao runs this flow on a community's own WhatsApp number. The matched member sees a short brief, never the requester's name, number or exact words, and taps Accept or Decline within 48 hours. Numbers are shared only after the requester has allowed it and the member has accepted, and both are checked again right before sending. See the [double opt-in introduction](https://milvao.com/glossary/double-opt-in-introduction) definition and [who sees what](https://milvao.com/privacy-and-consent).

## Frequently asked questions

### What is a double opt-in introduction email?

It is an email asking someone whether they want to be introduced to another person, sent before any contact details are shared. The introduction happens only when both people agree.

### Who should I ask first in a double opt-in introduction?

Usually the person being asked for help, since they are giving their time. The person who asked already wants the introduction, but confirm they still need it before you connect them.

### How long should I wait for a reply before giving up?

Send one reminder after a few days. If there is still no answer, treat it as a no and tell the requester you'll keep looking, without naming who you asked.
