Outlook Email Broken Layout Fix: Resolve Button Clickable Area Collapse for Transactional & System Notifications

Transactional emails (receipts, password resets, shipping alerts) carry critical operational data. Spacing collapses or broken buttons can block users from completing essential user journeys. Below is the targeted integration guide to fix Button Clickable Area Collapse inside Outlook Office 365 (Web) templates when using Campaign Monitor.

Technical Breakdown

Outlook Office 365 (Web) uses the Office Rendering Service which lacks support for standard rendering rules. This causes Button Clickable Area Collapse elements to break or collapse when rendering templates.

Campaign Monitor Behaviors

Campaign Monitor wraps custom blocks in dynamic edit tags, which can break the column flow inside Outlook. Ensuring correct class names is essential. Because system notifications are triggered frequently, ensure your CSS rules are completely inlined to guarantee readability in high-volume, automated delivery queues.

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 Campaign Monitor 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>
