What happens if the same number exists in multiple groups?

The system automatically handles duplicates to prevent sending the same message multiple times.

Automatic Duplicate Handling:

When you select multiple groups for a campaign:

1. System collects all contacts from selected groups
2. Identifies duplicate mobile numbers
3. Removes duplicates (keeps only one entry per number)
4. Sends one message per unique number

Example:

Group A: Premium Customers

• John: 9876543210
• Sarah: 9876543211

Group B: Newsletter Subscribers

• John: 9876543210 (duplicate)
• Mike: 9876543212

Result:

• Only 3 messages sent: John, Sarah, Mike
• John receives only ONE message (not two)
• Credits charged for 3 messages only

Personalization with Duplicates:

If using {{NAME}} placeholder:

• System uses the first occurrence found
• If John appears in both groups, uses name from first group processed
• Recommendation: Keep contact information consistent across groups

Additional Duplicate Filtering:

There’s also a “Filter Duplicates” setting:

• Enabled by default
• Removes duplicates within batch numbers
• Works alongside automatic group deduplication

Best Practices:

1. Don’t worry about duplicates – System handles it automatically
2. Verify contact names – Ensure names are consistent across groups
3. Check reports – Total recipients count shows final deduplicated count
4. Keep groups organized – Though duplicates are handled, clean data is better
