Best Practices

Email-Safe Design

Width: Always use 600px width for maximum email client compatibility
File Size: Keep images under 1MB for fast loading
Format: PNG for graphics with transparency, JPG for photos
Alt Text: Always include descriptive alt text for accessibility
Retina Support: Consider 1200px width scaled to 600px for retina displays

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:

Dimensions: Specify exact size (e.g., 600x300px)
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.
Industry: E-commerce, SaaS, fitness, fashion, etc.

Example Prompt Structure

"Create a [width]x[height]px email [banner type] for [industry/brand].
[Style description] with [color scheme].
Include space for [text elements like headline, CTA, logo].
[Mood/feeling] aesthetic."

Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

Mode	Best For	Speed	Quality
`max`	Final campaign banners, A/B testing winners	Slower	Highest
`eco`	Quick drafts, concept exploration, bulk variations	Faster	Good
