Why This Rejection Happens
Your sample messages show two distinct types of traffic (e.g., "Your code is 1234" AND "Check out our sale!"), but you selected a single-purpose use case like "2FA" or "Marketing".
Root Cause Analysis
The Fix
Change your campaign use case to Mixed or split the traffic into two separate campaigns (recommended for better deliverability).
✓ Correct Choice
Select "Low Volume Mixed" or "Mixed".
✗ Incorrect Choice
