Email Design Fundamentals
Visual Hierarchy
Visual hierarchy guides your reader's eye through your email content in order of importance. Use these principles to create a clear path from opening to action.

- • Neutral colors for supporting content
White Space
Strategic use of white space improves readability and creates a clean, professional appearance.

- • Avoid cramped layouts
- • Use padding and margins consistently
Typography Best Practices
Font Selection

Inverted Pyramid
Start with the most important information and narrow down to specific details.
