Email Not Displaying Correctly in Gmail: Fix Padding & Margin Collapsing for SendGrid for SaaS Product Operations
SaaS communications (onboarding guides, product updates, dashboard reports) require clean tech-first typography and functional UI component layout rendering. Below is the targeted integration guide to fix Padding & Margin Collapsing inside Gmail App (iOS & Android) templates when using SendGrid.
Technical Breakdown
Gmail App (iOS & Android) uses the WebKit / Blink which lacks support for standard rendering rules. This causes Padding & Margin Collapsing elements to break or collapse when rendering templates.
SendGrid Behaviors
SendGrid's template parser automatically injects custom style tags that can override inline styles. Always use inline style definitions and define clear target widths. Verify that your dashboard report layouts use nested tables. Flexbox layouts will fail in legacy Outlook clients used by enterprise software buyers.
Remediation Code Block
To ensure spacing works reliably, apply all structural paddings directly to HTML td elements inside tables. Do not apply paddings or margins to raw divs, as Outlook will strip them. For vertical spacing, use explicit spacer tables or empty rows. In your SendGrid campaign manager, make sure you configure your links to run via {{{unsubscribe}}}.

How to Deploy inside SendGrid
Copy the fixed VML or table wrapper code block from the remediation box above.
Open SendGrid Design Editor, toggle the view mode to Code Editor, or insert a custom 'Code' module block inside your drag-and-drop layout. Drop the corrected code inside the box.
