Does it write the email or just the prompt?

It builds the prompt. You paste it into your own LLM to generate the emails. Everything runs in your browser and nothing is sent anywhere.

Cold emails that get replies, not deletes

Most cold emails fail because they open with the sender’s product and read like a template blast. This builder produces a prompt that forces the opposite: problem-first, conversational, one clear ask, and a follow-up sequence — the structure that actually earns replies.

How it works

You provide five inputs — persona, pain point, value proposition, CTA, and length. The tool composes them into a prompt with hard rules baked in for the model: lead with the prospect’s problem, ban filler like “I hope this finds you well” and hype words, use a single low-friction CTA phrased as a question, and write a curiosity-driven subject line under six words.

The prompt always asks for three emails: the initial touch, a +3-day follow-up that adds a new angle, and a +5-day break-up email that is easy to say no to. It also inserts a {{placeholder}} so the sender drops in one researched detail, keeping the message from reading as mass-sent. Your chosen length swaps a single instruction block controlling word count and proof points.

Why the three-email structure matters

Most cold outreach sequences send one email and give up. The generated prompt always asks the model for three because the reply dynamics of cold outreach are well understood:

  • Email 1 (initial): Earns awareness. Even if the prospect does not reply, they have now seen your name and offer once.
  • Email 2 (+3 days, value-add): Adds a new angle — a case study, a relevant stat, a question they had not considered. Many replies come here from prospects who were interested but not ready.
  • Email 3 (+5 days, break-up): Short, low-friction, easy to say no to. “Should I close your file?” or “Is this worth 15 minutes?” often converts fence-sitters who feel the door closing.

After three emails, move on. More than three with no response is spam.

The personalization placeholder and why it works

The generated prompt inserts a {{researched_detail}} placeholder as the second sentence of the opening email. This is structural — it forces the sender to drop in one piece of research about the specific prospect before hitting send. It could be a recent company announcement, a shared connection, a problem visible from their job postings, or a content piece they published. One genuine line of research is worth more than five perfect sentences of template copy, because it signals that the email was written for them, not broadcast.

Tips for higher reply rates

  • Make the pain point specific and current — “tickets pile up overnight” beats “you want better support.” Specificity is what makes a stranger keep reading.
  • Keep your value prop to one quantified outcome; the model will not stack multiple claims if you give it one.
  • Always fill the personalization placeholder before sending — a researched line about the prospect’s company doubles the credibility of the whole email.
  • Keep the subject line under six words and avoid clickbait — a subject like “quick question about your onboarding” outperforms “Revolutionize Your CX!”
  • Send the follow-ups. The majority of positive replies arrive on email two or three, not email one.
