Outlook Email Broken Layout Fix: Resolve Broken SVG Image Vectors for WCAG Accessibility Violations
Accessibility failures prevent screen readers from navigating templates, isolating disabled subscribers and increasing unsubscribe rates. Below is the targeted integration guide to fix Broken SVG Image Vectors inside Outlook 2021 templates when using React Email.
Technical Breakdown
Outlook 2021 uses the Microsoft Word (MSO) which lacks support for standard rendering rules. This causes Broken SVG Image Vectors elements to break or collapse when rendering templates.
React Email Behaviors
React Email relies on compiling CSS parameters dynamically. However, React Email's compiler cannot parse raw MSO conditional comments or VML structures in TSX files directly. Inject correct table roles (role='presentation') and keep color pairings above the WCAG AA contrast threshold of 4.5:1.
Remediation Code Block
Always convert logo assets and icons from vector SVG formats into web-friendly PNG or JPG formats. If vector rendering is required, host the SVG on a CDN with an absolute URL and define a PNG fallback utilizing conditional comments. In your React Email campaign manager, make sure you configure your links to run via {unsubscribeUrl}.

How to Deploy inside React Email
Copy the fixed VML or table wrapper code block from the remediation box above.
Import the standard '<Html>' or '<Container>' primitives. To insert our VML or custom Outlook table markup directly, wrap the raw HTML snippet inside React's 'dangerouslySetInnerHTML' parameter on a div or span.
