Rainbow Email Generator

Two Python scripts for creating colorful, rainbow computer-styled HTML emails from Markdown content. Markdown is converted to colorful HTML for insertion into eMails. As each eMail is created, you can add a personalized message.

On Linux, Thunderbird can send each one automatically. Fork this repository and have AI walk you through adapting it to your operating system.

Step-by-Step Instructions

1. Write your email content

   • Edit email-input.md with your message in Markdown format
   • Use {{top}} placeholder where personalized content should go

2. Basic generation

   python3 rainbow_email.py

   • Converts email-input.md to colorful HTML
   • Copies HTML to clipboard automatically
   • Paste into email client with Ctrl+V

3. With personalized top content

   python3 rainbow_email.py "Hi **Sarah**! Hope you're *doing well*."

   • Replaces {{top}} with your personalized message
   • Supports bold, italic, and links

4. Generate preview file

   python3 rainbow_email.py --preview

   • Creates preview.html to view in browser
   • Also copies to clipboard

5. Save to file

   python3 rainbow_email.py "Hello!" --save my_email.html

   • Saves HTML to specified file instead of clipboard

Tool 2: Batch Processing (batch_rainbow_email.py)

Step-by-Step Instructions

1. Create recipient list

   • Make a text file (e.g., recipients.txt) with one email per line:

   sarah@example.com
   john@company.org
   mary@startup.io
   

2. Prepare base email

   • Write your template in email-input.md
   • Include {{top}} where personal content goes

3. Run batch processor

   python3 batch_rainbow_email.py "Subject Line" recipients.txt

4. For each recipient, the script will:

   • Show recipient email address
   • Prompt: "Enter personalized content (supports markdown):"
   • You type personalized message (supports bold, italic, links)
   • Press Enter twice to finish, or type 'skip' for no personalization
   • Generate HTML and copy to clipboard
   • Open email client with recipient and subject pre-filled
   • Auto-paste HTML content (if xdotool available)
   • Ask if you want to continue to next recipient

5. Options:

   # Create drafts (default)
   python3 batch_rainbow_email.py "Monthly Update" recipients.txt --drafts
