How to write a cold email people answer

Start with one reader and one reason

Before you write a word, finish this sentence: “I’m writing to [this person] because [something true about their situation] means [what I do] could help with [a problem they own].” If you can’t, the problem is the list, not the copy. Go back and find a reason, or a better person to write to.

Write for one reader, even if the campaign goes to five hundred. Picture a real person on the list and write to them. Then check that every sentence is still true for the others; if it isn’t, split the list.

The subject line

The subject line has one job: to tell the reader honestly what the email is about, in a way that makes it worth opening. Short, lower-key subjects tend to look like ordinary work email. Some patterns that work without tricks:

• The topic in a few words: “Onboarding for new hires at Acme”
• A question they’d recognise: “Who handles supplier invoices?”
• A reference to the reason: “Your new Leeds office”

Avoid fake replies (“Re:” on a first email), fake urgency, ALL CAPS and anything the email doesn’t deliver. Misleading subject lines are prohibited under CAN-SPAM and are a fast route to complaints. Try options in the subject line tester.

The first line

The first line shows in the preview next to the subject, so it decides whether the email gets read. Skip “I hope this finds you well” and “My name is”. Open with the reason you’re writing, in their terms:

• “Saw you’re hiring three support engineers in Lisbon.”
• “Your pricing page mentions invoicing in five currencies.”
• “You spoke about onboarding time at the Leeds meetup last month.”

Only use a detail if it’s true and relevant. A compliment on a podcast you didn’t listen to is worse than no personalisation at all.

A four-part structure

1. Why them: the reason you’re writing, in one sentence.
2. What you do: one sentence on the problem you solve, in the reader’s words, not your product’s.
3. Why it might matter now: one concrete detail, such as what a first step looks like or how long it takes. Only claim results you can back up.
4. One easy ask: a question they can answer in a line.

That is usually four to six sentences. If the email needs scrolling on a phone, it’s too long for a first message.

Asks that get replies

Ask for something small. A 30-minute call with a stranger is a big ask; a yes-or-no question is not. Good asks:

• “Is this something you look after, or is there someone better to ask?”
• “Worth a short call, or not a priority this quarter?”
• “Would a two-minute video of how this would look for you be useful?”

Ask one question per email. Two questions get zero answers.

Personalisation that is real

Personalisation is not inserting {{first_name}}. It’s the reason for writing. Use variables for the mechanics (name, company, the trigger you found) and write the reasoning yourself. If you research each lead, put the research in a custom field and reference it in the first line.

In Inboxed, variables like {{first_name}} and {{company}} fill from your lead list, with fallbacks for missing values, and the preview shows the email as a specific lead will see it. AI-written lines use your own AI provider account, and every draft can be reviewed before it sends.

Match the email to the reader’s role

The same offer needs different words for different people. Write about the problem as that person experiences it:

• A founder or managing director cares about outcomes and risk: revenue, cost, time, what could go wrong. Keep it shortest of all.
• A department head cares about their team’s targets and workload. Name the metric or process they own.
• A hands-on specialist cares about how it works. A concrete detail (the integration, the file format, the setup step) earns more trust than a benefit statement.

If you can’t say which of these you are writing to, you probably have two lists in one. Split them and write two versions.

Write in the reader’s language

If your leads work in different languages, write to each group in its own language rather than sending English to everyone, and have a native speaker check the template. Keep the same structure: a translated email that runs twice as long has lost the point. Store the language on the lead so the right version goes to the right person, and make sure your unsubscribe line and footer read naturally in that language too.

Proof without hype

A cold email can’t carry a case study, but it can carry one honest proof point: a customer in their industry who agreed to be named, a public number you can link to, or the specific thing you did for a similar team. If you don’t have proof yet, say what a first step looks like instead. Never invent results, logos or testimonials; it is dishonest, and a reader who checks will remember.

Format and length

• Plain text. No banners, logos or images in a first email.
• Short paragraphs of one or two sentences, so it reads well on a phone.
• At most one link, to your own domain. Better still, no link: let them reply.
• A real signature: your name, role, company. Inboxed adds the legally required footer (your company name, postal address and an unsubscribe line) under it.

Words and patterns that hurt

Filters and people react to the same things: hype, pressure and vagueness. Leave out “guaranteed”, “risk-free”, “act now”, exclamation marks, invented statistics and claims you can’t prove. Inboxed scans content before launch and blocks known spam patterns; the free spam word checker shows you the same kind of issues.

Examples

A weak first email

Subject: Quick question!!! — Hi {{first_name}}, I hope this finds you well. I’m reaching out because we are the leading platform for revolutionising customer success. Companies like yours see huge improvements. Do you have 30 minutes this week for a demo? [three links] [logo]

It’s about the sender, makes a claim it can’t back up, asks for a lot, and has no reason why this reader got it.

A better version

Subject: Support hiring in Lisbon — Hi Marta, saw Acme is hiring three support engineers in Lisbon. We help support teams get new hires answering tickets on their own sooner, by turning past tickets into a searchable playbook. Setup takes an afternoon with your help-desk export. Is ramping new hires something you look after, or is there someone better to ask? — Sam, Head of Partnerships, Example Co

It gives the reason, says what it does in the reader’s terms, keeps the claim modest and concrete, and ends with an easy question.

A question-only email

Subject: Supplier invoices at Acme — Hi Marta, quick one: who looks after supplier invoice processing at Acme? I’d like to send them a short note about how we handle multi-currency invoices. Thanks, Sam

Asking for the right person is honest, short and useful even when the answer is “not me”.

Variations at scale

When you send to many people, identical emails can look like bulk mail. Spintax lets you write alternatives such as {Hi|Hello} {{first_name}} so each lead gets one version. Inboxed picks a version per lead and step, consistently (a retry sends the same words), with nesting, weights and shuffled sentence order, and the editor previews the variations. Use it for small wording changes, never to hide what the email is.

Before you hit launch

• Read it aloud. Would you send this to one person you respect?
• Check every variable in the preview for three different leads.
• Remove one sentence. Then another, if it still works.
• Make sure the follow-ups each add something new.
• Check the footer: name, postal address, unsubscribe.

Need a starting point? The templates are short sequences in this style, such as Simple introduction and Ask before pitching.
