Email Not Displaying Correctly in Gmail: Fix Outlook Background Image Collapse for Brevo (Sendinblue) 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 Outlook Background Image Collapse inside Gmail Web (Desktop) templates when using Brevo (Sendinblue).
Technical Breakdown
Gmail Web (Desktop) uses the Goog/WebKit Layout Engine 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. 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 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]-->
