### Visual Guidelines

Text Space: Leave clear areas for text overlays
Contrast: Ensure text areas have sufficient contrast
Brand Consistency: Maintain consistent colors and style across campaigns
Mobile: Design with mobile email clients in mind (single column)
Safe Zones: Keep critical elements away from edges

### Content Tips

Clear Hierarchy: Most important information should be immediately visible
Single Focus: One main message per banner
CTA Visibility: Ensure call-to-action areas stand out
Minimal Text: Use supporting HTML text instead of image text when possible

### Prompt Tips for Email Banners

When creating email banners, include these details in your prompt:

Banner Type: Header, promotional, announcement, etc.
Color Scheme: Brand colors or desired palette
Text Space: Where headlines/CTAs will be placed
Style: Minimalist, bold, elegant, playful, etc.
