# Introduction email between two people, done the double opt-in way > Introduction email templates between two people: the double opt-in ask, the intro itself, the reply, and the forwardable blurb. Who goes in To, who in Bcc. Source: https://askmomo.app/templates/intro-email-between-two-people ยท Updated 16 October 2026 An introduction email between two people connects someone who wants something with someone who can give it. The double opt-in version asks the busier person first, in a separate email, before putting the two in the same thread. Use it any time you are spending someone else's attention: investors, senior hires, a client contact or anyone who gets more intros than they can take. ## How do you write an introduction email between two people? Ask the busier person first with a short forwardable note from the person asking. If they say yes, send one email with both in To, two lines on each person, one line on why they should talk, and a hand-off: "I will leave you to it." The person who asked for the intro replies first, moves you to Bcc, and proposes times. That is the whole protocol. ## Template 1: the opt-in ask, sent to the busier person only Use this before any intro to someone senior or in demand. Paste the requester's forwardable blurb below your note. ``` Subject: Intro to [Requester name]? Say no freely Hi [Name], [Requester name] ([one line: founder of X / head of Y at Z]) asked if I would introduce you. They want [the specific ask: 20 minutes on your experience hiring in Pune / feedback on their pricing / to pitch you for your fund's seed stage]. I think it is a fair use of your time because [one concrete reason]. If not, say no and nothing more will come of it. Their note is below. [Your name] --- [Forwardable blurb from the requester, three to five lines, written in first person: who they are, what they want, why this person.] ``` ## Template 2: the introduction itself, after both have said yes Use this once the opt-in is in. Both people in To, you as sender, and a clean hand-off. ``` Subject: [Name A] <> [Name B]: intro [Name A], [Name B], pleased to connect you. [Name A] is [one line on role and company]. [One line on what they are working on or need right now.] [Name B] is [one line on role and company]. [One line on why they are the right person for this, for example: has run exactly this kind of hiring at scale.] [Name A], over to you to suggest a couple of times that work. I will drop to Bcc so your calendars can take it from here. [Your name] ``` ## Template 3: replying to an introduction you received Use this when you are the person who asked for the intro. Reply within a day, move the introducer to Bcc and offer times. ``` Subject: Re: [Name A] <> [Name B]: intro Thanks [Introducer name], moving you to Bcc. [Name B], good to meet you. [One line on what you would like from the conversation and why it is worth their time.] Could we take 20 minutes on Google Meet? I can do: [Day, date], [time] IST [Day, date], [time] IST If neither works, send me a slot and I will make it work. [Your name] ``` ## Template 4: the forwardable blurb, written by the person asking Use this when you want an intro. Write it so the introducer can forward it without editing a word. ``` Subject: Forwardable note for [Target name] Hi [Introducer name], here is a note you can forward to [Target name] if you are comfortable making the intro. Happy to be told no. --- Hi [Target name], I am [Your name], [role] at [company]. We [one line on what the company does, in plain words]. I would like 20 minutes with you to [specific ask]. I am asking you in particular because [one concrete reason tied to their experience]. I will come prepared with [what you will bring: three specific questions / a one-page summary], and I will keep to the time. If this is not a good moment, no need to reply. [Your name], [phone or LinkedIn] ``` ## What to change before you send Introductions fail on small mechanics more than on wording. - Put both people in To on the intro, never one in Cc. Cc signals one of them matters less. - Say who should write first. Without that line, both wait for the other and the thread dies. - Keep each person to two lines. A paragraph of praise makes the other person feel they are being sold something. - Use the names each person actually goes by, spelt the way they sign their emails. - Check that the ask in the opt-in matches the ask in the intro. People say yes to "20 minutes on hiring" and feel misled by a pitch deck. - If the busier person said no, tell the requester kindly and without detail. Never forward the no. ## Why double opt-in, and when a single email is fine Asking first protects the person whose time is being asked for and protects your own standing with them. An unwanted intro costs them a polite decline in front of a stranger, and costs you the next intro. The ask itself is cheap: one short email with a forwardable blurb they can read in ten seconds. A single email is fine between peers who both expect it: two colleagues on the same project, two founders who both asked to meet, or anyone where the "ask" is symmetrical. When in doubt, ask. If the person you introduced has not replied to the intro within three working days, send one short nudge to them alone, not to the thread. [How to follow up on an email with no response](/blog/how-to-follow-up-on-an-email-with-no-response) has the wording. ## Let Momo AI do the thread Once the intro lands, the work is the scheduling thread that follows. Momo AI drafts your first reply in your writing style with two to four free slots from your Google Calendar, saves it to Gmail Drafts, and when the other person picks one it books the meeting with a Google Meet link and writes the confirmation. It also tracks intros you made that got no reply so you can nudge. You tap Send on everything. See [scheduling by email](/schedule-meetings-by-email) and how it works [for founders](/for/founders). ## Questions ### What is a double opt-in introduction? An introduction where the connector asks both people, especially the busier one, for permission before putting them in the same email thread. ### Who should reply first to an introduction email? The person who asked for the intro, within a day. They thank the introducer, move them to Bcc and propose times. ### Should I Cc or Bcc the person who introduced us? Move them to Bcc in your first reply so they see the intro landed and are spared the rest of the thread. ### How long should an introduction email be? Under ten lines: two for each person, one on why they should talk, and one saying who writes first. ## Related - [Book meetings over email, without sending a link](https://askmomo.app/schedule-meetings-by-email) - [Email templates you can copy, then stop writing by hand](https://askmomo.app/templates) - [Meeting request email templates, with time slots included](https://askmomo.app/templates/meeting-request-email) - [Follow-up email after no response: five templates you can copy](https://askmomo.app/templates/follow-up-email-after-no-response) - [How to follow up on an email with no response, with six polite templates](https://askmomo.app/blog/how-to-follow-up-on-an-email-with-no-response) --- Momo AI (Ask Momo, askmomo.app) is a personal AI assistant and chief of staff for Gmail and Google Calendar, built in India.
