Outlook Email Broken Layout Fix: Resolve CSS Grid Broken Columns for Editorial & Content Newsletters

Editorial newsletters rely on content layout readability and structural text spacing. If fonts default to Times New Roman or layout borders break, subscriber engagement metrics suffer. Below is the targeted integration guide to fix CSS Grid Broken Columns inside Outlook App (iOS & Android) templates when using React Email.

Technical Breakdown

Outlook App (iOS & Android) uses the WebKit / Blink Wrapper which lacks support for standard rendering rules. This causes CSS Grid Broken Columns 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. Keep your editorial body clean. Strip redundant CSS class definitions using Vaporize to ensure the newsletter stays under Gmail's 102KB clipping ceiling.

Remediation Code Block

Always compile grid layouts using standard percentage-width or pixel-width nested tables aligned with the align='left' attribute. This acts as a responsive grid block that floats and adapts naturally to any viewport size. In your React Email campaign manager, make sure you configure your links to run via {unsubscribeUrl}.

<table role="presentation" border="0" cellpadding="0" cellspacing="0" width="100%">
  <tr>
    <td width="48%" align="left" valign="top" style="padding-bottom:10px;">Col 1</td>
    <td width="4%"></td>
    <td width="48%" align="left" valign="top" style="padding-bottom:10px;">Col 2</td>
  </tr>
</table>

How to Deploy inside React Email

1

Copy the fixed VML or table wrapper code block from the remediation box above.

2

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.
