Outlook Email Broken Layout Fix: Resolve Gmail 102KB Layout Clipping for Transactional & System Notifications
Transactional emails (receipts, password resets, shipping alerts) carry critical operational data. Spacing collapses or broken buttons can block users from completing essential user journeys. Below is the targeted integration guide to fix Gmail 102KB Layout Clipping inside Outlook 2016 templates when using ActiveCampaign.
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.
ActiveCampaign Behaviors
ActiveCampaign's editor parses HTML template imports and automatically cleans inline attributes, which can break VML tags. Always use absolute styles and avoid relying on classes. Because system notifications are triggered frequently, ensure your CSS rules are completely inlined to guarantee readability in high-volume, automated delivery queues.
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 ActiveCampaign campaign manager, make sure you configure your links to run via %UNSUBSCRIBELINK%.

How to Deploy inside ActiveCampaign
Copy the fixed VML or table wrapper code block from the remediation box above.
Insert an 'HTML block' from the layout builder panels. Avoid standard text boxes, as the ActiveCampaign parser might strip conditional MSO comment strings on saving.
