Outlook Email Broken Layout Fix: Resolve Outlook Background Image 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 Outlook Background Image Collapse inside Outlook Office 365 (Web) templates when using Brevo (Sendinblue).
Technical Breakdown
Outlook Office 365 (Web) uses the Office Rendering Service which lacks support for standard rendering rules. This causes Outlook Background Image 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 resolve this in Outlook desktop, you must wrap your element or cell inside a Microsoft VML (Vector Markup Language) shapes structure that declares the background image explicitly using the 'v:background' or 'v:fill' vector properties. In your Brevo (Sendinblue) campaign manager, make sure you configure your links to run via {{ unsubscribe }}.
<td background="https://example.com/bg.jpg" bgcolor="#222222" valign="top" style="background-image: url('https://example.com/bg.jpg'); background-repeat: no-repeat; background-size: cover;">
<!--[if mso]>
<v:rect xmlns:v="urn:schemas-microsoft-com:vml" fill="true" stroke="false" style="width:600px;height:300px;">
<v:fill type="tile" src="https://example.com/bg.jpg" color="#222222" />
<v:textbox inset="0,0,0,0">
<![endif]-->
<div>Overlay Content</div>
<!--[if mso]>
</v:textbox>
</v:rect>
<![endif]-->
