Outlook Email Broken Layout Fix: Resolve Padding & Margin Collapsing 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 Padding & Margin Collapsing inside Outlook 2019 templates when using HubSpot.
Technical Breakdown
Outlook 2019 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.
HubSpot Behaviors
HubSpot's COS template manager automatically wraps content blocks in dynamic div structures to support their drag-and-drop system. These extra wrappers force styling inheritances that override inline td paddings, leading to spacing collapses in Outlook. Setting explicit table element attributes is crucial. 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 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 HubSpot campaign manager, make sure you configure your links to run via {{ unsubscribe_link }}.

How to Deploy inside HubSpot
Copy the fixed VML or table wrapper code block from the remediation box above.
In HubSpot's Design Manager, edit the modules section. Create a 'Rich Text' or 'HTML' module block. Double-click the block, choose 'Tools' or 'Advanced', click 'Source Code', and drop the code snippet inside.
