Highlighting text in your Klaviyo emails transforms ordinary messages into visually compelling communications that capture subscriber attention and drive engagement. Strategic text highlighting serves as a powerful tool for creating visual hierarchy, emphasizing critical information, and guiding readers through your content with purpose. When implemented correctly, these techniques can significantly improve click-through rates and overall campaign performance.
What Makes Text Highlighting So Effective
Text highlighting works because it mimics natural reading patterns and visual processing behaviors. Your subscribers scan emails quickly, looking for relevant information that stands out from the surrounding content. Highlighting creates visual anchors that draw the eye to specific elements like discount codes, deadlines, or special offers.

The psychology behind effective highlighting lies in contrast and visual hierarchy. When certain text elements appear different from the surrounding content, they automatically receive more attention from readers. This principle applies whether you’re changing text color, adding background highlights, or adjusting font weight to create emphasis.
Modern email clients support various highlighting techniques, though compatibility varies across platforms. Understanding these limitations helps you choose highlighting methods that work consistently across Gmail, Outlook, Apple Mail, and other popular email applications. The key is balancing visual impact with technical reliability to ensure your highlighted content appears as intended for all subscribers.
Basic Highlighting Techniques That Work Everywhere
The most reliable highlighting methods use standard formatting options available in Klaviyo’s text editor. Bold text provides strong emphasis without compatibility issues, making it perfect for highlighting important dates, product names, or key benefits. Italic text offers subtle emphasis that works well for quotes, testimonials, or secondary information that deserves attention.
Color changes represent another fundamental highlighting technique that works across most email clients. Klaviyo’s color picker allows you to select brand-consistent colors or choose from pre-defined options that ensure readability. When changing text color, consider contrast ratios to maintain accessibility standards while creating visual impact.

Font size adjustments create natural hierarchy within your email content. Larger text naturally draws attention, making it ideal for headlines, subheadings, or critical announcements. Combining size changes with other highlighting techniques amplifies the effect without overwhelming your design.
Advanced Color Selection Strategies
Klaviyo’s color picker offers multiple selection methods that support sophisticated highlighting strategies:
- Gradient field selection: Choose precise shades and hues for subtle highlighting effects
- HEX and RGB codes: Maintain exact brand color consistency across campaigns
- Recent colors: Access previously used colors for consistent highlighting patterns
- Eyedropper tool: Match colors from existing email elements for cohesive design
Brand consistency becomes crucial when selecting highlight colors. Using your established brand palette for highlighting reinforces visual identity while creating familiar patterns that subscribers recognize. Save frequently used colors in Klaviyo’s recent colors section to streamline future email creation and maintain consistency across campaigns.
Color psychology plays an important role in highlighting effectiveness. Red conveys urgency and importance, making it perfect for limited-time offers or deadlines. Yellow suggests attention and caution, working well for important notices or warnings. Blue communicates trust and reliability, suitable for highlighting guarantees or security features.
How Background Highlights Create Maximum Impact
Background highlighting mimics the familiar highlighter pen effect, creating strong visual emphasis that’s impossible to ignore. This technique works particularly well for short text elements like discount codes, phone numbers, or specific dates that require immediate attention. The background color creates a visual container that separates highlighted content from surrounding text.
Implementing background highlights requires careful consideration of color combinations and contrast ratios. Light background colors with dark text provide excellent readability, while dark backgrounds with light text create dramatic emphasis. The key is ensuring sufficient contrast to maintain accessibility while achieving the desired visual impact.
Padding adjustments around background-highlighted text improve readability and visual appeal. Klaviyo allows you to modify text block padding, creating breathing room around highlighted elements. This prevents highlighted text from appearing cramped or cluttered, especially when using multiple background highlights within the same email.
Strategic Placement for Background Highlights
Background highlights work best when used sparingly and strategically throughout your email content. Reserve this technique for truly critical information that subscribers must notice, such as expiration dates, exclusive offers, or important instructions. Overusing background highlights diminishes their effectiveness and creates visual chaos.
Consider the emotional impact of different background colors when highlighting text. Warm colors like yellow and orange create friendly, approachable emphasis suitable for positive messages. Cool colors like blue and green convey calm professionalism, perfect for highlighting factual information or guarantees. Bright colors demand immediate attention but should be used judiciously to avoid overwhelming subscribers.
The placement of background highlights within your email structure affects their impact. Highlights near the top of your email receive more attention than those buried in later paragraphs. Use this principle to prioritize your most important highlighted content in prime visual real estate.
Why the Styles Tab Transforms Your Workflow
Klaviyo’s main Styles tab offers a systematic approach to text highlighting that ensures consistency while reducing code weight. This method prevents email clipping issues that can occur when individual text blocks contain excessive formatting code. Setting universal styles creates a foundation that you can apply consistently across multiple campaigns.
The Styles tab allows you to define formatting for normal text and heading levels (H1-H4), creating a hierarchy that subscribers learn to recognize. When you consistently use specific styles for certain types of content, subscribers develop visual expectations that improve their email experience. This systematic approach also saves time during email creation.
Universal content blocks extend the Styles tab concept by allowing you to save complete formatted sections for reuse. Create text blocks with your preferred highlighting, then save them as universal content that appears in any email. This approach ensures brand consistency while streamlining the design process for frequent email senders.
Building Custom Highlight Libraries
Creating a library of custom highlight styles supports long-term email marketing success. Document your highlighting conventions in a style guide that specifies when and how to use different highlight techniques. For example, establish rules like using yellow backgrounds for discount codes and red text for urgent deadlines.
Font management through Klaviyo’s Brand Library provides another layer of highlighting customization. Upload custom fonts that align with your brand identity, then use these fonts for highlighting specific types of content. Custom fonts create unique visual signatures that subscribers associate with your brand.
Version control becomes important when managing custom highlight styles across team members. Establish clear guidelines about who can modify universal content blocks and how changes should be communicated. This prevents inconsistencies that can confuse subscribers and dilute your brand message.
What HTML Highlighting Unlocks for Power Users
HTML blocks in Klaviyo enable advanced highlighting effects that aren’t available through standard formatting options. Gradient text, custom spacing, and animated highlights become possible with HTML and CSS knowledge. These techniques create unique visual experiences that differentiate your emails from competitors.
Custom HTML highlighting requires careful testing across email clients due to varying CSS support. Always include fallback styling that ensures critical information remains highlighted even in clients with limited capabilities. This approach balances creative expression with practical reliability.
The complexity of HTML highlighting makes it most suitable for special campaigns or brands with dedicated design resources. Consider the time investment required for coding, testing, and troubleshooting against the potential visual impact. Simple highlighting techniques often provide better return on investment for most email marketers.
Advanced HTML Techniques Worth Exploring
Gradient text effects create sophisticated highlighting that stands out in crowded inboxes. CSS linear gradients can transform ordinary text into eye-catching elements that reinforce brand personality. However, these effects require thorough testing to ensure graceful degradation in unsupported email clients.
Custom spacing and typography effects through HTML allow precise control over highlighted text appearance. Adjust letter spacing, line height, and text shadows to create unique emphasis that aligns with your brand aesthetic. These subtle effects can significantly impact the perceived quality of your email design.
Animation effects for highlighted text should be used sparingly and with consideration for accessibility. Subtle animations can draw attention to important elements, but excessive motion can distract from your message or cause issues for subscribers with motion sensitivity. Always provide static alternatives for animated highlighting.
Best Practices That Maximize Highlighting Success
Effective highlighting follows the principle of strategic restraint—when everything is highlighted, nothing stands out. Reserve highlighting for truly important information that directly supports your email’s primary objective. This might include key benefits, special offers, deadlines, or calls-to-action that drive desired subscriber behavior.
Consistency in highlighting styles helps subscribers quickly identify important information based on familiar visual cues. Develop a highlighting system where specific colors or styles always represent certain types of content. This creates visual shortcuts that improve the subscriber experience and increase engagement with highlighted elements.
Accessibility considerations ensure your highlighting works for all subscribers, including those with visual impairments or color blindness. Use tools like WebAIM’s Contrast Checker to verify that your color combinations meet accessibility standards. Combine color highlighting with other emphasis techniques like bold text to ensure information remains accessible.
Testing across multiple devices and email clients prevents highlighting surprises after your campaign launches. What appears perfect in Klaviyo’s editor might render differently in various email applications. Send test emails to multiple addresses and check rendering across popular platforms before finalizing your campaign.
Measuring Highlighting Effectiveness
Track engagement metrics to understand how highlighting affects subscriber behavior. Monitor click-through rates on highlighted calls-to-action compared to non-highlighted elements. This data helps you refine your highlighting strategy and identify which techniques resonate most with your audience.
A/B testing different highlighting approaches provides concrete data about subscriber preferences. Test variations like color choices, highlighting intensity, or placement strategies to optimize your approach. Small changes in highlighting can produce measurable improvements in campaign performance.
Heat mapping tools can reveal how subscribers interact with highlighted elements in your emails. Understanding where subscribers focus their attention helps you optimize highlighting placement and intensity for maximum impact. This data-driven approach removes guesswork from your highlighting decisions.
Troubleshooting Common Highlighting Challenges
Email client inconsistencies represent the most frequent highlighting challenge. Styles that render perfectly in Gmail might appear differently in Outlook or Apple Mail. Address this by using simpler highlighting methods for critical information and testing extensively across platforms before sending campaigns.
Forwarding compatibility issues occur when email clients strip or modify CSS during the forwarding process. For information that subscribers might forward to others, use basic highlighting techniques like bold text or standard colors rather than complex styling. This ensures your highlighted content remains visible even after forwarding.
Code weight problems can cause email clipping when individual text blocks contain excessive formatting. Use Klaviyo’s main Styles tab instead of manually formatting each element to reduce code weight. This approach prevents clipping while maintaining consistent highlighting across your email.
Solutions for Platform-Specific Issues
Outlook-specific rendering problems often involve background colors and spacing inconsistencies. Test your highlighted content specifically in Outlook versions and adjust padding or color choices as needed. Consider providing Outlook-specific fallbacks for complex highlighting effects.
Mobile rendering requires special attention since highlighted text might appear differently on smaller screens. Ensure your highlighting remains effective and readable on mobile devices by testing across various screen sizes. Adjust font sizes and color contrasts specifically for mobile viewing when necessary.
Dark mode compatibility affects how highlighted text appears in email clients that support dark themes. Test your highlighting in both light and dark modes to ensure readability and visual impact remain consistent. Consider providing dark mode-specific styling for optimal appearance.
