Best Practices Email Design

Prioritize a mobile-first approach

A majority of emails are now opened on mobile devices, so optimizing for mobile is more critical than ever. Consider the following:

  • Use a responsive design that adapts to different screen sizes
  • Keep the email width between 320-600 pixels
  • Increase font sizes for better readability on small screens
  • Use larger buttons and touch targets to ensure easy navigation

Keep your layout clean and organized

Cluttered and disorganized emails can confuse readers and decrease engagement. To maintain a clean layout:

  • Use a single-column design for easy reading on mobile devices
  • Stick to a maximum of three fonts and colors to maintain visual harmony
  • Use white space strategically to separate elements and improve readability

Use eye-catching subject lines and preheader text

Compelling subject lines and preheader text can significantly impact your open rates. To make the most of these crucial elements:

  • Keep your subject lines under 50 characters
  • Use action words and personalize when possible
  • Craft engaging preheader text that complements the subject line and entices readers to open the email

Utilize strong visuals and imagery

Visuals play a vital role in capturing attention and setting the tone for your email content. To effectively incorporate visuals:

  • Use high-quality images that are relevant and support your message
  • Opt for illustrations or icons to break up text-heavy sections
  • Test image rendering on different devices and email clients to ensure consistency

Craft concise and engaging copy

Your email copy should be informative, valuable, and enjoyable to read. Remember these tips when crafting your copy:

Keep sentences short and paragraphs no longer than three lines
Use headings and subheadings to guide readers through the content
Employ bullet points and lists to present information in a digestible format
Write in a conversational tone and use “you” language

Emphasize your call-to-action (CTA)

CTAs are crucial for guiding readers to take the desired action. To make your CTAs more effective:

  • Place the primary CTA above the fold for easy visibility
  • Use a contrasting color and size to make the CTA button stand out
  • Keep the CTA copy short, clear, and action-oriented

Optimize email accessibility

Ensuring your emails are accessible to all users, including those with disabilities, is ethical and expands your potential reach. To create accessible emails:

  • Use descriptive alt text for images
  • Choose fonts with high readability and sufficient contrast
  • Employ a logical content hierarchy with headings and subheadings

Test and monitor email performance

Continuous testing and monitoring will help refine your email design for better results. Be sure to:

  • Test your emails on various devices and email clients
  • Track open rates, click-through rates, and conversion rates
  • Analyze results and make adjustments as needed

Personalize and segment your emails

Personalization and segmentation can significantly improve engagement and conversion rates. To effectively implement these strategies:

  • Use subscriber data to tailor content, offers, and recommendations
  • Segment your audience based on factors such as demographics, interests, and behavior
  • Test different personalization and segmentation approaches to find what works best for your audience

Apply email design psychology

Leveraging psychology in your email design can help influence your readers’ decisions and encourage action. Consider these psychological principles:

  • Consistency: Maintain a consistent design across all your emails to create a cohesive brand experience
  • Social proof: Showcase testimonials, reviews, or user-generated content to build trust and credibility
  • Scarcity: Use limited-time offers or exclusive content to create a sense of urgency

Ensure email deliverability

A well-designed email is only effective if it reaches your audience’s inbox. To maximize deliverability:

  • Maintain a clean and up-to-date email list
  • Avoid spam trigger words and phrases in your subject lines and copy
  • Authenticate your emails using Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and
  • Domain-based Message Authentication, Reporting, and Conformance (DMARC)

Encourage social sharing

Encouraging readers to share your content can expand your reach and attract new subscribers. To facilitate social sharing:

  • Include prominent social sharing buttons within your email design
  • Craft share-worthy content that appeals to your audience’s interests and values
  • Offer incentives for sharing, such as discounts or exclusive content

Consider adding interactive elements

Interactive elements can boost engagement and create memorable experiences for your readers. Some ideas to incorporate interactivity include:

  • Image carousels or galleries to showcase products or content
  • Quizzes or polls to collect feedback and engage readers
  • Animated elements or hover effects to add visual interest


Email design best practices are key to ensuring your emails are visually appealing, engaging, and effective in achieving your marketing goals. By prioritizing a mobile-first approach, maintaining a clean layout, crafting compelling subject lines and copy, using strong visuals, optimizing accessibility, and continually testing and monitoring, you can create emails that stand out in the inbox and drive results.
