How do I design emails for Right-to-Left (RTL) languages?

RTL email design for languages like Arabic, Hebrew, and Persian requires mirroring your entire layout, not just changing text alignment. Add dir=\"rtl\" to your HTML tag and body element. Text flows from right to left, but so should your visual hierarchy: navigation reads right-to-left, images that imply direction get flipped, and content columns reverse order. What was on the left is now on the right.

CSS logical properties help if your email client support allows: use margin-inline-start instead of margin-left to create direction-aware spacing. For broader compatibility, you may need separate RTL stylesheets or conditional CSS. Pay special attention to icons and images with directional implications-arrows, progress indicators, and illustrated sequences all need RTL versions.

Mixed-direction content adds complexity. English brand names or numbers embedded in Arabic text need proper bidirectional isolation using <bdi> tags or Unicode control characters to prevent rendering confusion. Test thoroughly with native speakers-RTL isn't just flipped LTR, and awkward layouts are immediately obvious to those who read these languages daily. RTL design done well shows respect for your audience; done poorly, it shows you ran English text through a mirror function and called it localization.
