Outlook Email Broken Layout Fix: Resolve Outlook Button Border Collapsing 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 Button Border Collapsing inside Outlook App (iOS & Android) templates when using Campaign Monitor.
Technical Breakdown
Outlook App (iOS & Android) uses the WebKit / Blink Wrapper which lacks support for standard rendering rules. This causes Outlook Button Border Collapsing 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. Enforce strict WCAG color contrast standards across your statement tables and summary grids to ensure legibility and regulatory compliance.
Remediation Code Block
To guarantee perfectly rounded buttons inside Outlook, we must generate a hybrid VML (Vector Markup Language) roundrect structure overlaid with normal HTML tables. VML is read only by Outlook, while WebKit clients read the HTML layout. 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.
