Email Not Displaying Correctly in Gmail: Fix Broken SVG Image Vectors for Salesforce Marketing Cloud (SFMC) for Client Rendering Engine Anomalies
Email client rendering variations are caused by differences in parser engines. Legacy Outlook engines ignore modern block models, forcing layouts to stack vertically. Below is the targeted integration guide to fix Broken SVG Image Vectors inside Gmail App (iOS & Android) templates when using Salesforce Marketing Cloud (SFMC).
Technical Breakdown
Gmail App (iOS & Android) uses the WebKit / Blink which lacks support for standard rendering rules. This causes Broken SVG Image Vectors elements to break or collapse when rendering templates.
Salesforce Marketing Cloud (SFMC) Behaviors
SFMC's Content Builder wraps block exports in div frames that can break conditional comments. Additionally, AMPScript calls for personalizations can trigger parsing errors if they are inside MSO conditional comments. Ensure your AMPScript tags are evaluated *outside* the VML blocks. Test layout code regressions side-by-side using the Campaign Diff Comparator before pushing visual style changes to your production templates.
Remediation Code Block
Always convert logo assets and icons from vector SVG formats into web-friendly PNG or JPG formats. If vector rendering is required, host the SVG on a CDN with an absolute URL and define a PNG fallback utilizing conditional comments. In your Salesforce Marketing Cloud (SFMC) campaign manager, make sure you configure your links to run via %%unsubscribe_url%%.
