Outlook Email Broken Layout Fix: Resolve Button Clickable Area Collapse for Deliverability & Spam Audits
Spam filters analyze email HTML code quality alongside body copy. Unclosed tags, excessive styling block nesting, and broken link parameters are flagged as spam risks. Below is the targeted integration guide to fix Button Clickable Area Collapse inside Outlook 2019 templates when using React Email.
Technical Breakdown
Outlook 2019 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.
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. Run your finished layouts through the Spam Word Auditor to catch trigger phrases and verify structural delivery alignments before launching.
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 React Email campaign manager, make sure you configure your links to run via {unsubscribeUrl}.
<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="{unsubscribeUrl}" style="color: #ffffff; text-decoration: none; display: block; font-family: sans-serif; font-size: 14px; font-weight: bold;">Click Here</a>
</td>
</tr>

How to Deploy inside React Email
Copy the fixed VML or table wrapper code block from the remediation box above.
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.
