Outlook Email Broken Layout Fix: Resolve Button Clickable Area Collapse for Retail & Consumer Brand Campaigns
Retail campaigns rely on high-fidelity visual assets, coupon borders, and clear promotional layouts. Default image blocking or button collapses disrupt the visual journey. Below is the targeted integration guide to fix Button Clickable Area Collapse inside Outlook 2013 templates when using Brevo (Sendinblue).
Technical Breakdown
Outlook 2013 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.
Brevo (Sendinblue) Behaviors
Brevo's rendering system injects inline spacing helpers to support their responsive editor, which can cause column overlaps in Outlook. Using explicit table alignments is required. Always define ALT descriptions for retail product shots, and base64-encode your brand logo so the email headers render cleanly even when images are blocked.
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 Brevo (Sendinblue) 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>
