Email Not Displaying Correctly in Gmail: Fix Outlook Background Image Collapse for HubSpot for eCommerce Campaigns

In eCommerce email marketing, rendering issues directly tank conversion rates and cart recoveries. Product grids, checkout CTAs, and discount banners must display flawlessly to prevent purchase drop-offs. Below is the targeted integration guide to fix Outlook Background Image Collapse inside Gmail App (iOS & Android) templates when using HubSpot.

Technical Breakdown

Gmail App (iOS & Android) uses the WebKit / Blink which lacks support for standard rendering rules. This causes Outlook Background Image Collapse elements to break or collapse when rendering templates.

HubSpot Behaviors

HubSpot's COS template manager automatically wraps content blocks in dynamic div structures to support their drag-and-drop system. These extra wrappers force styling inheritances that override inline td paddings, leading to spacing collapses in Outlook. Setting explicit table element attributes is crucial. Double-check your dynamic product feed blocks. When injecting product loops from your catalog, ensure width sizes are explicitly handled to keep columns from overlapping.

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 HubSpot campaign manager, make sure you configure your links to run via {{ unsubscribe_link }}.

<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>
