Outlook Email Broken Layout Fix: Resolve Padding & Margin Collapsing for Retail & Consumer Brand Campaigns
Retail campaigns rely on high-fidelity visual assets, coupon borders, and clear promotional layouts. Default image blocking or button collapses disrupt the visual journey. Below is the targeted integration guide to fix Padding & Margin Collapsing inside Outlook 2021 templates when using Campaign Monitor.
Technical Breakdown
Outlook 2021 uses the Microsoft Word (MSO) which lacks support for standard rendering rules. This causes Padding & Margin 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. Always define ALT descriptions for retail product shots, and base64-encode your brand logo so the email headers render cleanly even when images are blocked.
Remediation Code Block
To ensure spacing works reliably, apply all structural paddings directly to HTML td elements inside tables. Do not apply paddings or margins to raw divs, as Outlook will strip them. For vertical spacing, use explicit spacer tables or empty rows. 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.
