# Cold email generator: run it free, or from your agent

A subject line and three short cold email drafts from your offer, audience and one proof point.

## Prompt

Use looot to draft cold emails. I sell [offer] to [audience]. Proof: [one real result]. 1. Set up https://looot.ai/skill.md. 2. Search the catalog for a chat completion endpoint and check its price before you call. 3. Ask a small model for one subject under 50 characters and three emails under 45 words, each ending in one question, using only my facts. 4. Return the drafts and the cost.

## What it needs

What you sell, who you write to and one proof point

## What comes back

- one subject line
- three email drafts under 45 words
- spam words found in the drafts

## Endpoints and providers

- openrouter: openrouter-chat

## What it costs

The tool on the web page runs live at no cost to you and is limited per hour. The results come from public data through looot. For heavier or repeated use, run the same job from your own looot account: looot bills per call and charges nothing while your agent is idle. The live price comes from the catalog and shows on the web page.

## Beat the blank page

Get three angles in seconds: the problem, the proof and the direct ask.

## Stay out of spam

Each draft is checked for risky words before you copy it.

## Test angles

Send each version to a small group and keep the one that gets replies.

## Write at scale

Your agent drafts per lead from your own looot account with the same rules.

## How does the cold email generator work?

You fill in what you sell, who you write to and one proof point. An AI model with fixed instructions writes a subject and three short drafts, and the page checks them for spam words.

## Is this cold email generator free?

Yes. Each run in the box costs you nothing and is limited per hour. Your agent can run the same job from your own looot account at the price shown above.

## Which AI model writes the drafts?

Gemma 4 31B, an open model from Google, run through OpenRouter. The answer is capped at a few hundred tokens, enough for a subject and three short emails.

## Will it make up results or customers?

It is told to use only the facts you give and to invent nothing. Models can still slip, so read each draft and remove any claim you cannot back up.

## Do you store what I type?

No. This page does not save or log your text or the drafts. Your text is sent once to the model provider through looot, and the drafts go only to your browser.

## Why are the emails so short?

Short cold emails are easier to read on a phone and to answer. Each draft stays under 45 words and ends with one question. Add a personal first line for each lead before you send.

## Can I make variations for a sequence?

Yes. Run it again for new drafts, or turn your favorite into spintax with the spintax generator to vary each send.

## How do I run this from an agent with looot?

Give your agent the skill.md link from the prompt above. It calls the openrouter-chat endpoint with a model, a system message with your rules, your facts as the user message and a max_tokens cap.
