What does Boomerang do?

Boomerang is the warm-intro orchestration layer for B2B sales. We map every warm path from your team, customers, investors and board, and advisors into your priority accounts. When a signal fires (intent surge, champion job change, executive leadership move), we surface the warmest path, draft the intro request in the connector's voice, and close the loop when the meeting books.

Who is Boomerang for?

Boomerang is built for B2B SaaS and enterprise sales teams with at least $30k ACV, a customer base with active champions, and an engaged board or advisor network. Particularly powerful for account-based selling motions, founder-led GTM, and teams trying to break into senior buyer altitudes.

How is Boomerang different from 6sense, ZoomInfo, or Outreach?

Signal layers like 6sense and ZoomInfo identify which accounts are in market. Sequencers like Outreach and Salesloft scale cold outreach. Both stopped converting senior buyers as cold reply rates fell 70 percent. Boomerang adds the warm-intro activation layer those tools structurally cannot carry. We sit on top of your existing stack; we do not replace it.

Free tool · no signup

Introduction email generator.

Write the email that introduces two people, the double opt-in check that comes before it, or the forwardable blurb you send when you are the one asking to be introduced.

1 · Which side are you on?

2 · Person one

Name

Role and company

What they are looking for

Finish: "They are..." Keep it to one specific thing.

3 · Person two

Name

Role and company

What they bring

Finish: "They..." The reason the other person should care.

4 · You

Your first name

How you know them

Always ask first

A double opt-in intro means you check with both sides before connecting them. It takes one extra message and it is the difference between a useful introduction and an ambush. Never cc two people who have not agreed to meet.

Write it to be forwarded

If you are asking for an intro, write the blurb in the third person so your connector can forward it without editing a word. The easier you make it to pass on, the more often it actually gets passed on.

Give them an exit

Every intro request should make no an easy answer. A connector who feels cornered will simply not reply, and you lose the relationship as well as the intro.

Knowing who to ask is the hard part.

This writes the email once you know which connection to use. Boomerang finds the paths for you across your executives, investors, customers and partners, scores which one is strongest, and tells you who internally should make the ask.

Worked examples

Six introduction emails, written out in full.

Every message below is the exact output of the generator above. The first three introduce a VP of Engineering to a recruiter using the double opt-in sequence. The last three are the other side: asking a connector for an introduction, with a blurb written to be forwarded as is.

Introducing two people, the full double opt-in

The complete sequence. Two short permission notes, then the introduction itself once both have said yes. Send the first two and wait.

Asking an investor for an introduction

The forwardable blurb plus the note to your connector. The blurb is third person on purpose so it can be forwarded without editing.

Subject line

Quick ask: intro to Marcus?

Alternatives: Would you forward this to Marcus? · Intro to Marcus at COO at Brookfield?

The forwardable blurb · written so it can be sent as is

Alex Moreau is founder of Northwind. We cut the time legal teams spend on lease abstraction. For context, three firms their size cut abstraction review from days to hours. Worth a short conversation if the timing is right.

The note to Dana

Hi Dana,

I know you two overlap with Marcus Hale, COO at Brookfield. Would you be willing to introduce us?

I have written something forwardable below so you do not have to write anything yourself. If this is not a fit, no is a completely fine answer.

Hope things are good with you.

I know you two overlap with Marcus Hale, COO at Brookfield. I would love an introduction, but only if you think it is a fit.

I have written the note below so you can forward it as it is, without writing anything yourself. And if this is not one you want to make, no is a completely fine answer and I will not ask twice.

Asking a former colleague, very short

Minimum viable ask. Still forwardable, still gives an exit.

Questions people ask about introduction emails

How do you introduce two people over email?

Ask both of them first, separately, then send one email to both. The introduction itself has four parts: a subject line with both names, one sentence introducing each person to the other, one line on why you think they should talk, and an explicit handover so they know you are stepping back.

Keep each description to a single specific fact rather than a summary of someone's whole career. "Tomas places platform engineers at seed to Series B startups" is more useful than three sentences of background.

What is a double opt-in introduction?

A double opt-in introduction means you check with both people privately before connecting them, and only send the introduction once both have said yes. It takes one extra message to each side and it is the difference between a useful introduction and an ambush.

The alternative, cc'ing two people who never agreed to meet, puts both of them in an awkward position: one now has an obligation they did not ask for, and the other is waiting on a reply that may never come.

Should you ask permission before introducing two people?

Yes, in almost every case. The exception is when both sides have already explicitly asked to meet each other, in which case you are just opening the thread.

Asking costs you two short messages. Not asking costs you credibility with whichever person did not want the introduction, and they will be more hesitant the next time you offer one.

How do you write an introduction email between two parties?

Subject line with both first names. "Maya <> Tomas" is the common convention and it makes the thread easy to find later.
Open to both at once, then introduce each person to the other in one sentence with a specific detail.
Say briefly why you are making this introduction, so neither has to guess.
Hand over explicitly. Something like "I will step back now" tells them the next move is theirs.
Move yourself to bcc on any reply so you are not cluttering their thread.

How do you ask someone to introduce you?

Make it as close to zero work as possible. Write a short paragraph about yourself in the third person that your connector can forward without editing a word, and put it in the message clearly separated from the rest.

Then give them an exit. A line like "if this is not a fit, no is a completely fine answer" makes it easy to decline, which matters because a connector who feels cornered will often just not reply at all. You lose the relationship as well as the introduction.

What is a forwardable blurb?

A forwardable blurb is a short third-person description of you and your ask, written so your connector can paste or forward it straight to the other person. It is third person because they are the one sending it: "Alex is the founder of Northwind" works when forwarded, "I am the founder of Northwind" does not.

It is the single hardest part of the whole process and the most common reason introductions never actually get sent. If your connector has to write anything themselves, the request moves to the bottom of their list.

What should an introduction email include?

Both names in the subject, one specific line about each person, the reason for the connection, and a clear handover. What it should not include: a full biography, a pitch, an agenda, or a proposed meeting time. The introduction opens the door. Whatever happens next belongs to the two of them.

How do you introduce yourself in an email?

That is a different job from this tool, which introduces two other people or asks for an introduction. But the structure is similar: say who you are in one line, say why you are writing in the next, make one specific ask, and stop. Most self-introductions fail by explaining background before getting to the point.

If there is any shared connection between you and the recipient, mention it in the first sentence. A referenced relationship outperforms a cold opening by a wide margin, which is why the name-drop email generator exists.

How do you know who can introduce you in the first place?

That is the harder half, and no template solves it. The path usually exists somewhere across your company already: an executive who worked with the person, an investor whose portfolio overlaps, a customer who used to be their colleague. It is just not written down anywhere one person can see. Boomerang maps those paths, scores which is strongest, and tells you who internally should make the ask.
