Fix CSS Grid Broken Columns in iOS Mail (Apple) — React Email Guide for B2B Cold Outreach
B2B cold outreach templates demand maximum deliverability and a plain-text appearance. Heavy, broken CSS structures or HTML syntax issues trigger spam filters instantly. Below is the targeted integration guide to fix CSS Grid Broken Columns inside iOS Mail (Apple) templates when using React Email.
Technical Breakdown
iOS Mail (Apple) uses the WebKit Mobile which lacks support for standard rendering rules. This causes CSS Grid Broken Columns elements to break or collapse when rendering templates.
React Email Behaviors
React Email relies on compiling CSS parameters dynamically. However, React Email's compiler cannot parse raw MSO conditional comments or VML structures in TSX files directly. For cold sales outreach, minimize VML structures and prioritize light, standard text blocks to maximize inbox placement on corporate enterprise filters.
Remediation Code Block
Always compile grid layouts using standard percentage-width or pixel-width nested tables aligned with the align='left' attribute. This acts as a responsive grid block that floats and adapts naturally to any viewport size. In your React Email campaign manager, make sure you configure your links to run via {unsubscribeUrl}.
<table role="presentation" border="0" cellpadding="0" cellspacing="0" width="100%">
<tr>
<td width="48%" align="left" valign="top" style="padding-bottom:10px;">Col 1</td>
<td width="4%"></td>
<td width="48%" align="left" valign="top" style="padding-bottom:10px;">Col 2</td>
</tr>

How to Deploy inside React Email
Copy the fixed VML or table wrapper code block from the remediation box above.
Import the standard '<Html>' or '<Container>' primitives. To insert our VML or custom Outlook table markup directly, wrap the raw HTML snippet inside React's 'dangerouslySetInnerHTML' parameter on a div or span.
