WhatsApp Quality Rating and Messaging Limits
The number of unique daily customers a business can message on the WhatsApp Business API is governed by Meta's **Messaging Limit Tiers**. Scaling these limits depends directly on maintaining a healthy **Quality Rating**.
What is WhatsApp Quality Rating?
Quality Rating reflects customer feedback on messages sent over the past 7 days: Green (High), Yellow (Medium), Red (Low).
Messaging Limit Tiers
Tiers scale from Tier 1 (1,000 unique users/24h) up to Tier 4 (Unlimited), upgrading automatically when 50% of current capacity is utilized with high quality ratings.
