WhatsApp Rate Limits: Sending Without Tripping Meta's Systems

What the limits actually are

Meta applies per-number sending limits that scale with business verification, number age, and quality. New numbers start with little headroom; verified, aged numbers with green quality get far more.

• Hard ceilings exist but are not published as fixed universal numbers
• Business verification raises the ceiling
• Number age and history build headroom
• Quality is the moving variable that tightens or loosens everything

The quality rating system

Every number carries a quality rating — green, yellow, or red — visible in Meta Business Manager.

• Green: normal sending, keep the current practices
• Yellow: sending reduced; review opt-in and recent volume
• Red: sending restricted or paused until quality recovers
• Rating follows reports, opt-outs, and spam signals

Growing a new number

A new number is like a new credit file: there is no history, so there is no headroom.

• Start with service messages and replies, not broadcasts
• Grow business-initiated volume gradually over weeks
• Send to engaged, opted-in contacts first
• Spread sends instead of bursting a campaign in one hour

What trips the limits

The triggers are predictable and mostly voluntary.

• Broadcasts to lists without opt-in
• High volume to cold contacts who never replied
• Identical bulk text with links
• Ignoring STOP replies and re-adding opted-out contacts
• Bursts of volume from a young number

Operating inside the limits

The limit is a dial, not a wall: good behavior turns it up.

• Watch the quality rating weekly
• Reduce volume the moment yellow appears
• Fix the cause — usually list quality — before resuming
• Verify the business to raise the ceiling
• Keep opt-in evidence so every send is defensible
