Outlook Email Broken Layout Fix: Resolve Gmail 102KB Layout Clipping for eCommerce Campaigns
In eCommerce email marketing, rendering issues directly tank conversion rates and cart recoveries. Product grids, checkout CTAs, and discount banners must display flawlessly to prevent purchase drop-offs. Below is the targeted integration guide to fix Gmail 102KB Layout Clipping inside Outlook 2013 templates when using React Email.
Technical Breakdown
Outlook 2013 uses the Microsoft Word (MSO) which lacks support for standard rendering rules. This causes Gmail 102KB Layout Clipping 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. Double-check your dynamic product feed blocks. When injecting product loops from your catalog, ensure width sizes are explicitly handled to keep columns from overlapping.
Remediation Code Block
To resolve this, you must run your layouts through a specialized tree-shaking parser. Unused CSS selectors must be shaken off, styling rules inlined, comments removed, classes shortened, and layouts compressed to fit well under 100KB. 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.
