Outlook Email Broken Layout Fix: Resolve CSS Grid Broken Columns 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 CSS Grid Broken Columns inside Outlook Office 365 (Web) templates when using HubSpot.

Technical Breakdown

Outlook Office 365 (Web) uses the Office Rendering Service which lacks support for standard rendering rules. This causes CSS Grid Broken Columns elements to break or collapse when rendering templates.

HubSpot Behaviors

HubSpot's COS template manager automatically wraps content blocks in dynamic div structures to support their drag-and-drop system. These extra wrappers force styling inheritances that override inline td paddings, leading to spacing collapses in Outlook. Setting explicit table element attributes is crucial. 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

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 HubSpot 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>
