What are Email Marketing Coding Standards?
Email marketing coding standards are a set of best practices and guidelines that ensure your
email campaigns are visually appealing, functionally reliable, and accessible across different email clients and devices. These standards help in maximizing the effectiveness of your email marketing efforts by ensuring that emails render correctly and provide a good user experience.
Cross-Client Compatibility: Different email clients (e.g., Gmail, Outlook, Yahoo) render HTML emails differently. Adhering to coding standards helps ensure that your emails look consistent across all platforms.
Mobile Responsiveness: With a significant portion of users now checking emails on their mobile devices, it's vital to follow standards that guarantee your emails are mobile-friendly.
Accessibility: Ensuring your emails are accessible to people with disabilities is not just ethically important but also broadens your reach.
Deliverability: Proper coding can help in avoiding spam filters, thereby improving your email deliverability rates.
Use Inline CSS: Most email clients strip out external CSS. Therefore, always use inline styles for better compatibility.
Table-Based Layouts: While modern web design uses divs and CSS for layout, email clients often render table-based layouts more consistently.
Alt Text for Images: Always include alt text for images to improve accessibility and provide context if images do not load.
Responsive Design: Use media queries and fluid grids to make your emails responsive.
Test Extensively: Use tools like Litmus or Email on Acid to test how your email renders in various clients.
Avoid Unsupported CSS: Some CSS properties are not supported by all email clients. Stick to the basics like font-size, color, and background.
Use Standard Fonts: Use web-safe fonts like Arial, Helvetica, and Georgia to ensure text displays correctly.
Semantic HTML: Use semantic HTML elements like <h1> to <h6> for headings to improve screen reader compatibility.
Contrast Ratios: Ensure sufficient contrast between text and background colors for readability.
Keyboard Navigation: Make sure all interactive elements are accessible via keyboard.
Litmus: A comprehensive tool for testing email compatibility across various clients.
Email on Acid: Another excellent tool for email testing and optimization.
W3C Validator: Use it to check the HTML validity of your emails.
