WhatsApp Messaging Limits and Quality Rating Explained
Short answer
WhatsApp limits how many customers a business can start conversations with in a rolling 24 hours, and scores your number’s quality from customer feedback such as blocks and reports. Good engagement and business verification can raise your limit; poor feedback can lower it or restrict your templates.
Your number’s reputation with WhatsApp is a real asset, and easy to damage with one careless broadcast. Understanding limits and quality rating helps you scale campaigns without losing the ability to send them. Meta updates these systems, so verify details in Meta’s current documentation.
Messaging limits
Meta caps how many unique customers you can start business-initiated conversations with in a rolling 24-hour period. New or unverified accounts begin with a lower limit and can move up through tiers as they send quality messages and complete business verification. Limits apply to business-initiated messages; replying to customers who message you is not restricted in the same way.
Tier names and thresholds have changed over time and may be applied at the business-portfolio level. Check Meta’s documentation for the current structure rather than relying on a fixed number.
Quality rating
Meta rates the quality of your messaging using recent feedback such as blocks, reports and how customers respond. The rating is commonly shown as high, medium or low.
- High: healthy engagement and few negative signals.
- Medium: warning territory; look at recent campaigns.
- Low: at risk of a reduced limit or restrictions on sending.
What hurts your rating
- Messaging contacts who never opted in. See opt-in.
- Sending too many marketing messages, or irrelevant ones.
- Templates that are misleading or badly categorised.
- No easy way to opt out.
- Ignoring customers who ask you to stop.
How to protect and grow your limit
- Complete business verification.
- Start campaigns with your most engaged contacts and expand gradually.
- Segment. Relevant messages get fewer blocks. See the broadcast guide and WhatsApp broadcast software.
- Make templates clear, honest and correctly categorised.
- Honour opt-outs immediately.
- Watch delivery, read and block trends after every campaign.
If your rating drops
- Pause non-essential broadcasts.
- Review the last few campaigns: audience, wording, frequency.
- Remove contacts who did not opt in or who never engage.
- Resume with smaller, better-targeted sends and watch the rating recover.
Support conversations are less affected than broadcasts, since replies inside the 24-hour window are customer-initiated.
