# How to Generate Email Headers with ChatGPT

ChatGPT combines email marketing knowledge with visual generation, suggesting header designs that drive higher open-to-click rates. Describe your campaign and audience, and ChatGPT creates headers optimized for email rendering. The conversational approach produces both the visual and suggested subject lines together.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT via MCP settings
2. Describe the email header: "I need a banner for our welcome email series"
3. ChatGPT generates the header image and shows it in conversation
4. Refine: "Make it warmer and add a friendly illustration"
5. Ask for headers for each email in your drip sequence

## Example Prompt

```
Create an email header for our welcome series. Warm, inviting design that says "Welcome aboard!" with friendly abstract illustrations. 600x200 pixels.
```

## Tips

- ChatGPT can suggest header designs based on your email campaign goals
- Ask for A/B test variations to optimize open-to-click rates
- Request matching headers for an entire drip campaign sequence
