Outlook Email Broken Layout Fix: Resolve Button Clickable Area Collapse for Client Rendering Engine Anomalies

Email client rendering variations are caused by differences in parser engines. Legacy Outlook engines ignore modern block models, forcing layouts to stack vertically. Below is the targeted integration guide to fix Button Clickable Area Collapse inside Outlook 2016 templates when using Klaviyo.

Technical Breakdown

Outlook 2016 uses the Microsoft Word (MSO) which lacks support for standard rendering rules. This causes Button Clickable Area Collapse elements to break or collapse when rendering templates.

Klaviyo Behaviors

Klaviyo's drag-and-drop template parser automatically wraps all user-defined block sections in proprietary 'kl-part' class selectors. When rendering templates inside Microsoft Word engines (Outlook 2007-2021), Klaviyo's nested flex fallback blocks can cause structural tables to collapse or shift columns. You must use explicit table widths to override Klaviyo's styling wraps. Test layout code regressions side-by-side using the Campaign Diff Comparator before pushing visual style changes to your production templates.

Remediation Code Block

To maintain button structural size and clickable areas, apply paddings to the parent table cell (td tag) rather than the link element, and format the anchor tag style to display: block. In your Klaviyo campaign manager, make sure you configure your links to run via {% unsubscribe %}.

<table role="presentation" border="0" cellpadding="0" cellspacing="0" style="border-collapse:collapse;">
  <tr>
    <td bgcolor="#6366F1" style="padding: 10px 20px; border-radius: 4px;">
      <a href="{% unsubscribe %}" style="color: #ffffff; text-decoration: none; display: block; font-family: sans-serif; font-size: 14px; font-weight: bold;">Click Here</a>
    </td>
  </tr>
</table>

How to Deploy inside Klaviyo

1

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

2

Open your Klaviyo template editor. Drag an 'HTML' block directly into your layout timeline (do not use a standard text box). Clear the default skeleton content inside the Klaviyo markup editor and paste the RenderOps corrected inline code.
