How to write a first cold email someone answers
Write it about them, not you. Open with one specific line tied to something they wrote, said or shipped, explain in one sentence why that made you write, and end with one clear ask that is easy to say yes to. Keep it short enough to read on a phone, send it from a real person's mailbox, and cut anything that reads like a template.
The five parts of a first cold email
- Subject: a few plain words about their world, not your product. Lowercase and specific beats clever.
- Opener: one line that proves you looked, tied to something they wrote or did.
- Reason: one sentence on why that made you write to them in particular.
- Proof: one short line that makes you credible, such as a similar customer or a result. Skip it if you have nothing true to say.
- Ask: one question with one easy answer.
That is usually four to six sentences. If you can read it aloud in under 30 seconds, the length is right.
An opener tied to what they wrote
The first line decides whether the rest gets read, and most inbox previews show only that line. Generic praise ("I love what you are doing at Acme") reads as automated because it could be sent to anyone. A good opener names something only this person did:
- A post or article: "Your post on closing the books in four days made the case for daily reconciliation better than anything I have read."
- A job listing: "Saw you are hiring two AP specialists in Lisbon."
- A talk or podcast: "In your talk last month you said onboarding is where churn starts."
- A launch or change: "Congrats on opening the Munich office."
Then connect it to your reason in the next sentence. The opener earns attention only if the email that follows is actually about that thing.
One clear ask
Two asks halve your replies because the reader has to choose. Pick the smallest step that moves your goal forward, and make the answer a single word if you can.
| Goal | Weak ask | Clear ask |
|---|---|---|
| A meeting | Let me know if you'd like to chat sometime. | Worth 15 minutes on Thursday or Friday? |
| A referral | Do you know anyone who might be interested? | Who on your team owns supplier payments? |
| Feedback | I'd love your thoughts. | Would you answer two questions by email? |
| An intro | Could you help me connect with people? | Would you be open to introducing me to Maria? |
A worked example
Subject: Revolutionize your finance operations
Hi Sarah, I hope this email finds you well. I'm the founder of Ledgerbird, the leading AI platform for finance teams. We help companies save time and money with automation. Do you have 30 minutes for a demo, and could you also forward this to your team?
Subject: your four day close
Hi Sarah,
Your post on getting the close down to four days stuck with me, especially the part about chasing receipts on day three.
We built a tool that collects receipts from approvers before month end, and two teams your size now close a day earlier with it.
Worth 15 minutes on Thursday to see if it fits?

The second version is shorter, names one thing she wrote, makes one modest claim and asks for one thing.
What to cut
- Pleasantries that delay the point, such as "I hope this email finds you well".
- Claims you cannot back, such as "leading" or "best in class".
- Attachments and images in a first email. They look like marketing and can hurt delivery.
- More than one link. Zero is fine.
- A long signature with banners and badges. Name, role, company and one link is enough.
- A misleading subject line, such as a fake "Re:". It is deceptive and, in the US, against CAN-SPAM.
Do not rely on open tracking to judge an email. Some mail apps, such as Apple Mail with Mail Privacy Protection, load images automatically, so opens are unreliable. Count replies instead.
Doing this for more than a few people
The hard part is that a real opener takes research for every person. Reach gives each person their own draft: Scout finds the right people, Writer reads what they have written and drafts one personal email per person, and you approve every email before Courier sends it from your own mailbox. Before you send, check the rules for the recipient's country, and plan your follow-ups.
Checklist
- The subject is a few plain words about their world.
- The first line names something only this person wrote or did.
- One sentence says why that made you write.
- Any proof is true and specific.
- There is exactly one ask, and it is easy to answer.
- It reads aloud in under 30 seconds.
- No attachments, no images, at most one link.
- It comes from a real person with a plain signature.
- You would be happy to receive it yourself.
Frequently asked questions
How long should a first cold email be?
Short enough to read on a phone in one screen, usually four to six sentences. Length matters less than every sentence being about the reader.
What is a good opening line for a cold email?
A specific reference to something the person wrote, said or shipped, such as a post, a talk, a job listing or a launch, followed by why it made you write. Generic praise that could go to anyone does not count.
Should I ask for a meeting in the first email?
You can, if the ask is small and specific, such as 15 minutes on a named day. If a meeting is a big step for this person, ask for something smaller first, such as whether they are the right person or whether you can send a short answer to a question.
Should I include a link or attachment?
Skip attachments in a first email. At most one link, and only if it helps the reader. A plain text email from a real person is the most natural format.
Do open rates tell me if my email works?
Not reliably. Some mail apps load tracking images automatically, so opens are inflated. Judge an email by replies.
