Email Preview Different from Actual Rendered Email
The emails generated by your v0 application look perfect in the development preview or React Email preview tool, but render completely differently when received in Gmail, Outlook, Apple Mail, or other email clients. Layouts break, images disappear, fonts change, and carefully styled components look mangled.
Email clients have notoriously inconsistent HTML and CSS support. Gmail strips most CSS, Outlook uses the Word rendering engine for HTML, and many clients block external images by default. V0 often generates email templates using modern CSS features like flexbox, grid, or CSS variables that are not supported by major email clients.
The gap between what you see in the browser preview and what recipients actually see can be dramatic, especially for complex layouts with multiple columns, custom fonts, or interactive elements.
Error Messages You Might See
Email layout broken in Outlook
Images not loading in Gmail
CSS styles stripped from email
Font not rendering in email client
Dark mode inverting email colors
Common Causes
- Modern CSS not supported — flexbox, grid, CSS variables, and custom properties do not work in most email clients
- External stylesheets stripped — Gmail and Outlook remove link tags and most head styles; only inline CSS is reliable
- Images blocked by default — many clients block external images until the user explicitly allows them
- Outlook Word renderer — Microsoft Outlook uses Word's HTML engine which has extremely limited CSS support
- Dark mode inconsistencies — email clients apply dark mode differently, inverting colors unpredictably
How to Fix It
- Use React Email components — install @react-email/components which generates email-safe HTML with table-based layouts
- Inline all CSS — use a CSS inliner like juice to convert stylesheet rules to inline styles before sending
- Use table-based layouts — replace flexbox and grid with HTML tables for reliable cross-client rendering
- Test across clients — use Litmus or Email on Acid to preview your email in 90+ email clients simultaneously
- Provide alt text for images — always include descriptive alt text since images may be blocked by default
- Add dark mode meta tag — include
<meta name="color-scheme" content="light dark">and provide dark mode color overrides

Get HelpFrequently Asked Questions
Why does my email look different in Outlook?
Outlook desktop uses Microsoft Word's HTML rendering engine, which only supports a subset of CSS. Use table-based layouts and inline CSS for Outlook compatibility.
Should I use React Email for templates?
Yes, @react-email/components generates email-safe HTML using table layouts. It provides components like Section, Row, Column that compile to email-compatible markup.
How do I test emails in multiple clients?
Use services like Litmus or Email on Acid for cross-client testing. For free testing, send to Gmail, Outlook, Yahoo, and Apple Mail accounts manually.
