HTML Email Development

HTML Email Techniques

• Table-Based Layout: Email clients don't support Flexbox/Grid — use nested <table> elements for layout. role='presentation' for accessibility. width='100%' for fluid containers
• Inline Styles: Most email clients strip <style> blocks — inline all CSS on elements. Use tools like Juice or MJML to automate inlining from a stylesheet
• Client Quirks: Outlook uses Word's rendering engine (not a browser). Gmail strips <style> in non-AMP emails. Apple Mail is the most standards-compliant. Test everywhere
• Responsive Email: Use max-width on outer table, media queries in <style> (when supported), fluid images (max-width: 100%), stacked layout for mobile
• MJML Framework: Write email in simplified markup — <mj-section><mj-column><mj-text>. Compiles to compatible HTML. Handles client quirks automatically
• Testing: Litmus or Email on Acid — preview in 90+ email clients without sending. Test rendering, links, images, dark mode, and accessibility
