WhatsApp assigns a Quality Rating and Broadcast Tier to every WhatsApp Business number. These directly impact how many messages you can send and how reliably they are delivered.
Quality Rating
The Quality Rating reflects how recipients respond to your messages.
Based on:
User blocks and reports
Message relevance
Engagement patterns
Quality levels:
High
Medium
Low
A low rating can result in messaging restrictions or reduced delivery.
Broadcast Tier
The Broadcast Tier defines how many unique users you can message within a 24-hour window.
Key points:
Higher tiers allow higher message volume
Tier upgrades depend on message quality and delivery history
Tier limits are managed by WhatsApp, not manually set
