Email clients are not browsers. Small HTML mistakes can turn into broken layouts, clipped content, or spammy rendering. Use this tool as a fast feedback loop while iterating on templates.
Tips for production templates
- Prefer inline styles or email-safe CSS.
- Keep HTML simple: tables beat modern layout for compatibility.
- Always include a plain-text alternative if your sending flow supports it.
- Use real unsubscribe links and your physical address for compliance.
