Email White Space

Definition

White space, also called negative space, is the empty area surrounding text, images, buttons and other design elements in an email. It is not wasted space — it is a deliberate design tool that separates content into scannable sections, gives the eye breathing room and draws attention toward the elements that matter most.

Emails crammed with content and lacking white space feel overwhelming and are more likely to be deleted unread. Strategic white space makes even long emails feel manageable and signals professionalism and design maturity.

Types of White Space

• Macro white space: Large gaps between major sections such as between the header and body, or between content blocks and the CTA
• Micro white space: Small spacing within elements — line height in paragraphs, padding inside buttons, margins around images
• Active white space: Space deliberately added to guide attention toward a focal point
• Passive white space: Natural spacing that occurs from element boundaries

Best Practices

• Increase line height to at least 1.4 for body text to prevent lines from crowding each other
• Surround primary CTAs with generous white space so they stand out from surrounding content
• Use consistent spacing values throughout the email rather than variable gaps
• On mobile, white space becomes even more important — smaller screens benefit from fewer elements with more room around each one
