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 2013 templates when using MJML Framework.
Technical Breakdown
Outlook 2013 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.
MJML Framework Behaviors
The MJML transpilation compiler parses dynamic columns and wraps them in custom HTML conditional tags. If you paste direct tables or VML code blocks inside an MJML layout without proper escaping, the MJML compiler will try to clean the code, resulting in stripped Outlook namespaces and broken layouts. 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 MJML Framework campaign manager, make sure you configure your links to run via {{unsubscribe_link}}.

How to Deploy inside MJML Framework
Copy the fixed VML or table wrapper code block from the remediation box above.
Wrap the entire RenderOps corrected table block inside an '<mj-raw>' tag block. This tells the MJML compiler to bypass parsing on this segment, exporting the exact conditional statements into the final HTML output.
