Write a cold outreach email to potential clients for my [product/service]

Optimized Claude Prompt

<context>
The user wants to generate a cold outreach email to potential clients. The goal of the email is to introduce a specific product or service and encourage the recipient to take a next step. The email needs to be persuasive and professional, capturing the recipient's attention quickly.
</context>

<task>
As a seasoned B2B marketing copywriter, your task is to write a compelling cold outreach email. The email should effectively introduce the user's [product/service] to potential clients. Focus on clearly articulating the value proposition and prompting a specific, low-friction call to action.
</task>

<requirements>
*   **Personalization Hooks:** Include 2-3 placeholders for personalization (e.g., `[Client Company Name]`, `[Specific Pain Point]`, `[Recipient Name]`). This is crucial for making the email feel less generic and more relevant to the individual recipient.
*   **Value Proposition:** Clearly articulate the primary benefit(s) of the [product/service]. Focus on solving a specific problem or achieving a desired outcome for the client, rather than just listing features. Aim for 1-2 core benefits.
*   **Conciseness:** Keep the email body concise, ideally between 150-200 words. Busy professionals appreciate brevity and getting straight to the point.
*   **Clear Call to Action (CTA):** Define a single, clear, and low-commitment CTA. Examples include scheduling a brief call, visiting a specific landing page, or downloading a resource. Avoid multiple or demanding CTAs.
*   **Subject Line:** Craft 2-3 distinct subject line options that are attention-grabbing and relevant, aiming for a high open rate.
*   **Professional Tone:** Maintain a professional, respectful, and confident tone throughout the email.
</requirements>

<format>
*   Present the final email clearly.
*   List the subject line options separately above the email body.
*   Use standard email formatting (salutation, body paragraphs, closing, signature placeholder).

Before finishing, verify your response covers the core ask of writing a cold outreach email for a specific product/service, including personalization, value proposition, and a clear CTA.
