If your campaigns suddenly stop sending, you may have hit a messaging limit. WhatsApp assigns each number a tier that caps how many new conversations you can start per day. Here is how tiers and rate limits work in 2026, and how to scale safely.
What are messaging tiers
Messaging tiers limit how many unique customers you can message in a rolling 24-hour window. New numbers start lower and move up automatically as you send quality messages and maintain a good rating.
The typical tier ladder
- Start with a modest daily conversation cap on a new number.
- Higher tiers unlock larger daily limits.
- Top tiers allow effectively unlimited new conversations.
How to move up tiers
- Keep your quality rating green by sending relevant, opted-in messages.
- Grow volume steadily rather than spiking overnight.
- Verify your business to raise your ceiling.
- Reduce blocks and reports with useful content.
Avoiding rate-limit issues
Spread large sends over time, keep lists clean, and monitor delivery. Sudden failures usually mean you hit a cap or your quality dropped.
