# AI email writer: run it free, or from your agent

A subject line and a short email body from your goal and key points. Missing facts stay as [placeholders].

## Prompt

Use looot to draft an email: goal [goal], recipient [role], key points [points]. 1. Set up https://looot.ai/skill.md. 2. Search the catalog for a chat completion endpoint and check its price. 3. Run it with a system prompt that asks for a subject under 60 characters and a body under 140 words, using only my facts and [placeholders] for the rest. 4. Return the draft for me to edit.

## What it needs

A goal, a recipient role, a tone and key points up to 500 characters

## What comes back

- subject line
- email body
- sign-off with placeholder

## 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.

Let your agent draft replies through looot and leave the sending to you.

## What does the AI email writer return?

A line starting with Subject:, then a body under 140 words and a sign-off with [Your name]. Facts you did not give stay as [placeholders].

## Will it make up details?

The prompt forbids invented names, numbers, dates and links. Models can still slip, so read the draft before you send it.

## Can it write cold sales emails?

It writes any short email from your brief. Follow the anti-spam law of your country, and check addresses with the email checker before you send.

## How long can the input be?

200 characters for the goal, 100 for the recipient and 500 for the key points. The answer is capped at 250 tokens.

## Is it free?

Yes on this page, limited per hour. Each run is one real call on looot's own key, billed per output token. The price for your own account is shown above.

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

Copy the prompt above into your agent. It sets up looot from skill.md, finds the chat completion endpoint and drafts the email with the same rules.

## Is my text stored?

The brief goes to the model provider for this one call. Do not paste personal or confidential data.
