What is a fallback value in variable mapping?
Fallback Values for Variables
A fallback value is a default placeholder text used when a variable has no data in your uploaded file. It ensures every recipient receives a coherent message, even with missing personalizations.
✅ Why Use a Fallback?
- Prevents messages from failing when data is missing
- Keeps tone professional and user-friendly
- Maintains campaign continuity without delays
- Protects template approval by avoiding broken personalization
📊 Before / After Example
Template:
Hi , your order of ₹ will be delivered on .
Scenario | Message Output | Result |
|---|---|---|
Without Fallback | | ❌ Awkward, broken message |
With Fallback ("Customer") | | ✅ Clean, professional output |
🛠️ Where to Set Fallback Values
- Upload your contact list during campaign setup.
- On the Variable Mapping screen, locate each placeholder (e.g.,
{{name}},{{delivery_date}}). - Next to each variable, enter a Fallback Value (e.g.,
Customer,N/A,TBD). - Click Preview to validate how the message will render.
⚠️ Edge Cases & Solutions
Issue | Impact | Recommended Action |
|---|---|---|
No fallback + missing data | Message may fail or look broken | Always define a fallback |
Fallback too long | May truncate or cause template rejection | Keep ≤ 25 characters |
Unsupported fallback types | Media or rich content not allowed | Use plain text only |
Visual mismatch | Layout may look off in preview | Test with sample data and preview |
🧠 Pro Tips
- Use neutral fallbacks like “Customer” or “there” for universal readability.
- Preview with missing data rows to confirm tone and formatting.
- Keep fallbacks policy-compliant (no promotional text inside Utility templates).
- Save your most-used fallbacks for reuse across campaigns.
