Outlook Email Broken Layout Fix: Resolve CSS Grid Broken Columns for B2B Cold Outreach

B2B cold outreach templates demand maximum deliverability and a plain-text appearance. Heavy, broken CSS structures or HTML syntax issues trigger spam filters instantly. Below is the targeted integration guide to fix CSS Grid Broken Columns inside Outlook 2013 templates when using MJML Framework.

Technical Breakdown

Outlook 2013 uses the Microsoft Word (MSO) which lacks support for standard rendering rules. This causes CSS Grid Broken Columns elements to break or collapse when rendering templates.

MJML Framework Behaviors

The MJML transpilation compiler parses dynamic columns and wraps them in custom HTML conditional tags. If you paste direct tables or VML code blocks inside an MJML layout without proper escaping, the MJML compiler will try to clean the code, resulting in stripped Outlook namespaces and broken layouts. For cold sales outreach, minimize VML structures and prioritize light, standard text blocks to maximize inbox placement on corporate enterprise filters.

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 MJML Framework campaign manager, make sure you configure your links to run via {{unsubscribe_link}}.

<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 MJML Framework

1

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

2

Wrap the entire RenderOps corrected table block inside an '<mj-raw>' tag block. This tells the MJML compiler to bypass parsing on this segment, exporting the exact conditional statements into the final HTML output.
