HTML and CSS that survive real-world email clients.
Recommended
Robust email layout tables
Use a simple presentation-table scaffold where client support requires it, without leaking table semantics into the reading experience.
RecommendedInline CSS and safe fallbacks
Inline critical presentation, keep selectors simple, and design fallbacks for clients that remove style blocks or ignore unsupported properties.
RequiredResponsive email layout
Messages must fit narrow screens, preserve readable type, and keep controls usable even when media queries or viewport hints are ignored.
