Fix Outlook Background Image Collapse in iOS Mail (Apple) — Brevo (Sendinblue) Guide for Financial Services & Banking

Financial emails carry high-compliance requirements. Layout collapses, overlapping text, or accessibility failures can lead to compliance audits and client confusion. Below is the targeted integration guide to fix Outlook Background Image Collapse inside iOS Mail (Apple) templates when using Brevo (Sendinblue).

Technical Breakdown

iOS Mail (Apple) uses the WebKit Mobile 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. Enforce strict WCAG color contrast standards across your statement tables and summary grids to ensure legibility and regulatory compliance.

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]-->
</td>
