Summary Metrics

Read count may be lower than actual reads — recipients with read receipts turned off are not counted.

  • Use body_0, body_1, NOT body1 or Body_0
  • Case-sensitive
  • Numbering starts from 0

  • Proper UTF-8 encoding

​
Troubleshooting

Check:
  • Template is APPROVED
  • Phone number is CLOUD_API
  • CSV format is correct
  • Phone numbers in international format
Issue: Template shows {{1}} instead of valuesSolution:
  • Verify CSV column headers match exactly
  • Check body_0, body_1 numbering
  • Ensure no typos in headers
Common causes:
  • Invalid phone numbers
  • Blocked by recipients
  • WhatsApp account limits reached
Solution:
  • Validate phone numbers
  • Check Meta quality rating
  • Spread campaigns over time
Why: Many users disable read receiptsNote: This is normal. Seen count only includes users with read receipts ON. Actual read rate is likely higher.
