Outlook Email Broken Layout Fix: Resolve Gmail 102KB Layout Clipping for Financial Services & Banking
Financial emails carry high-compliance requirements. Layout collapses, overlapping text, or accessibility failures can lead to compliance audits and client confusion. Below is the targeted integration guide to fix Gmail 102KB Layout Clipping inside Outlook 2016 templates when using Campaign Monitor.
Technical Breakdown
Outlook 2016 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.
Campaign Monitor Behaviors
Campaign Monitor wraps custom blocks in dynamic edit tags, which can break the column flow inside Outlook. Ensuring correct class names is essential. Enforce strict WCAG color contrast standards across your statement tables and summary grids to ensure legibility and regulatory compliance.
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 Campaign Monitor campaign manager, make sure you configure your links to run via [unsubscribe].

How to Deploy inside Campaign Monitor
Copy the fixed VML or table wrapper code block from the remediation box above.
