Email Not Displaying Correctly in Gmail: Fix Custom Font Fallback Overrides for Campaign Monitor for SaaS Product Operations
SaaS communications (onboarding guides, product updates, dashboard reports) require clean tech-first typography and functional UI component layout rendering. Below is the targeted integration guide to fix Custom Font Fallback Overrides inside Gmail Web (Desktop) templates when using Campaign Monitor.
Technical Breakdown
Gmail Web (Desktop) uses the Goog/WebKit Layout Engine which lacks support for standard rendering rules. This causes Custom Font Fallback Overrides elements to break or collapse when rendering templates.
Campaign Monitor Behaviors
Campaign Monitor wraps custom blocks in dynamic edit tags, which can break the column flow inside Outlook. Ensuring correct class names is essential. Verify that your dashboard report layouts use nested tables. Flexbox layouts will fail in legacy Outlook clients used by enterprise software buyers.
Remediation Code Block
To prevent Outlook's Times New Roman fallback override, wrap your custom font declarations inside an @media block that Outlook ignores, or use MSO conditional statements to override font-families specifically for Microsoft Word rendering engines. In your Campaign Monitor campaign manager, make sure you configure your links to run via [unsubscribe].

How to Deploy inside Campaign Monitor
Copy the fixed VML or table wrapper code block from the remediation box above.
In Campaign Monitor, click the 'Source' button on your selected editable text region, or edit the template code files directly. Ensure you append the 'class="cs-editable"' flag if you need inline editing later.
