Cold Email Generator: Short, Specific, and About Them

Why Use This Cold Email Generator?

Cold emails fail for one reason more than any other: they are about the sender. “We are a leading provider of…” has never started a reply.

The recipient owes you nothing and is deciding in under two seconds whether this is relevant to them.

Write my cold email

From one real run

“Small sync automation — worth a look?”

One of the subject options it returned for a logistics prospect.

From a real run: “Head of Operations at a 40-person logistics firm”, rekeying delivery data between two systems, offered a small sync automation, friendly tone.

How to Use the Cold Email Generator

  1. Describe who you are writing to and what problem they likely have.
  2. Add one specific detail about them. This is what stops it reading as a template.
  3. Generate and cut. Whatever comes out, it is probably too long.

The Structure That Works

Five parts, each with one job. Under 120 words in total.

Subject3–5 wordsLook like a real person, not a campaign
Opening line1 sentenceSomething specific about them
The problem1–2 sentencesName it in their language
Proof1 sentenceOne relevant result, not a list
The ask1 sentenceSmall, specific, easy to say yes to

The Opening Line Does All the Work

One sentence proving this email was written for them and not sent to four hundred people. It does not need to be clever. A recent hire, a product launch, something on their careers page, a post they wrote.

The point is not flattery — it is evidence that you looked before you wrote.

Generic vs specific

“We are a leading provider of workflow solutions.”

“Saw you opened a second depot last month — congratulations.”

Cold Email Subject Lines

Three to five words. Lower case. No punctuation tricks. Subject lines that look like marketing get treated as marketing. Ones that look like a colleague wrote them get opened.

Reads as marketing

“Transform Your Onboarding Process Today!”

Title case, an exclamation mark, and a promise. Filed accordingly.

Reads as a colleague

“quick question about onboarding”

Outperforms the other every time, and it is not close.

The Ask That Gets Answered

Make it small. “Are you the right person to talk to about this?” is answerable in four words. “Can we book a 30-minute discovery call next week?” asks for a calendar commitment from someone who has not decided you are worth it yet.

Get the reply first. Get the meeting second.

The Follow-Up Matters More Than the First Email

Most replies come from follow-ups, not the original. Two or three, spaced several days apart, each adding something new rather than repeating the ask.

“Just bumping this” adds nothing and reads as pressure. A relevant example or a different angle gives them a fresh reason to engage.

Being straight with you

What it writes, and what you still have to do

  • It is rule-based, not an AI model. Nothing is sent anywhere. The email is assembled in your browser from the role, problem, offer and tone you enter.
  • It is a starting draft. Our run returned 186 words across 4 blocks; the cold email itself was 62 words, inside the under 120 target. Add the specific detail only you know before you send it.
  • It cannot research your prospect. The opening line is only specific if you put something specific in. It has no access to their site, their hiring page or their news.
  • It does not send anything or check deliverability. Sending, sequencing and spam checks are your tools, not this one.
  • The email box is the one thing that leaves your browser, and only if you submit it.
