Email Not Displaying Correctly in Gmail: Fix Default Image Blocking Layouts for Klaviyo 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 Default Image Blocking Layouts inside Gmail App (iOS & Android) templates when using Klaviyo.
Technical Breakdown
If layouts rely on images for structural spacing or navigation, blocking image downloads by default will collapse the structural boxes.
Klaviyo Behaviors
Klaviyo's drag-and-drop template parser automatically wraps all user-defined block sections in proprietary 'kl-part' class selectors. When rendering templates inside Microsoft Word engines (Outlook 2007-2021), Klaviyo's nested flex fallback blocks can cause structural tables to collapse or shift columns. You must use explicit table widths to override Klaviyo's styling wraps. 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, always define explicit width and height attributes on your images to preserve their layout boxes when blocked. Add robust alternative (ALT) text styled with CSS font-sizes and colors, and encode vital brand logos directly as Base64 data URIs. In your Klaviyo campaign manager, make sure you configure your links to run via {% unsubscribe %}.
<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADIA..." width="150" height="40" alt="Company Logo" style="display: block; font-family: sans-serif; font-size: 14px; color: #111111; font-weight: bold; border: 0;">Live Code Sandbox Test
How to Deploy inside Klaviyo
Copy the fixed VML or table wrapper code block from the remediation box above.
Open your Klaviyo template editor. Drag an 'HTML' block directly into your layout timeline (do not use a standard text box). Clear the default skeleton content inside the Klaviyo markup editor and paste the RenderOps corrected inline code.
