Dynamic Content Preview & QA
Validate your conditional rules, loops, and fallback variables in real time inside the PostBrix preview suite.
Key Takeaways
- Toggle between raw template syntax mode (showing {{variables}}) and rendered data mode.
- Switch between light and dark backgrounds during live dynamic preview.
- Inspect the generated HTML output side-by-side with the rendered visual iframe.
Live Dynamic Preview Modes#
The PostBrix Preview Modal features two key view modes:
- Syntax Mode: Displays the raw template with curly brace tags visible. Perfect for copywriters verifying where variables are placed.
- Hydrated Data Mode: Evaluates the Handlebars engine against your active Sample Data JSON. Loop items are repeated, conditions are evaluated, and fallbacks are tested.
Dynamic Content QA Checklist#
Before exporting your email template:
- Verify that all personalized greetings resolve cleanly without trailing spaces when names are missing.
- Confirm that repeated product items maintain equal vertical alignment across columns.
- Test conditional discount banners with both
trueandfalseflag states. - Verify that dynamic link URLs form valid destinations when query parameters are appended.
Frequently Asked Questions
Why does my dynamic preview show empty space where a condition was placed?
If a conditional block evaluates to false, its content collapses completely. If you see remaining blank space, check if the parent section or column has fixed padding applied.
Can I send a live test email with hydrated sample data?
Yes. In the "Send Test" dialog, choose "Hydrate with active Sample Data" to receive the fully populated preview email in your inbox.
