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 App (iOS & Android) templates when using Klaviyo.
Technical Breakdown
Outlook App (iOS & Android) uses the WebKit / Blink Wrapper which lacks support for standard rendering rules. This causes Gmail 102KB Layout Clipping elements to break or collapse when rendering templates.
Klaviyo Behaviors
Klaviyo's drag-and-drop template parser automatically wraps all user-defined block sections in proprietary 'kl-part' class selectors. When rendering templates inside Microsoft Word engines (Outlook 2007-2021), Klaviyo's nested flex fallback blocks can cause structural tables to collapse or shift columns. You must use explicit table widths to override Klaviyo's styling wraps. 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 Klaviyo campaign manager, make sure you configure your links to run via {% unsubscribe %}.

How to Deploy inside Klaviyo
Copy the fixed VML or table wrapper code block from the remediation box above.
Open your Klaviyo template editor. Drag an 'HTML' block directly into your layout timeline (do not use a standard text box). Clear the default skeleton content inside the Klaviyo markup editor and paste the RenderOps corrected inline code.
