To prevent exposed code in your email campaigns, consider the following best practices:
Use Inline CSS: Always use inline CSS instead of external stylesheets to ensure compatibility across different email clients. Validate Code: Use HTML and CSS validators to check for errors before sending out the email. Test Across Clients: Test your emails across multiple email clients and devices to ensure consistent rendering. Use ESP Templates: Utilize templates provided by your ESP as they are often optimized for compatibility. Minimize Copy-Paste: Avoid copying and pasting from word processors; use plain text editors if necessary.
