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:

1. Dimensions: Specify exact size (e.g., 600x300px)
2. Banner Type: Header, promotional, announcement, etc.
3. Color Scheme: Brand colors or desired palette
4. Text Space: Where headlines/CTAs will be placed
5. Style: Minimalist, bold, elegant, playful, etc.
6. 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?"
