Your messaging limit, not your plan, decides how many people you can reach today.
The four tiers
The limit counts unique customers you start conversations with in a rolling 24-hour window, not total messages. Replying inside an open conversation does not consume it.
New numbers start at the entry tier and move up automatically. Business verification is required before a number can progress past the first step.
- 1,000 unique customers per 24 hours, the starting tier
- 10,000 unique customers per 24 hours
- 100,000 unique customers per 24 hours
- Unlimited, once the number has a sustained record
Quality rating is the real control
Meta scores each number high, medium or low based on recent recipient behaviour. Blocks and "report business" actions push it down; replies and reads keep it up.
A low rating stops progression and can push a number back down a tier. In the worst case the number is restricted from sending entirely. This is why opt-out handling and segmentation matter commercially rather than only legally.
How to climb faster
The pattern that works is boring: send to people who genuinely opted in, send something relevant, and increase volume gradually rather than in one spike.
- Complete business verification before anything else, since progression is gated on it.
- Start with your most engaged segment, not the whole list.
- Increase daily volume steadily instead of jumping from 200 to 50,000.
- Watch the quality rating weekly and stop if it dips.
- Make opting out easy, because an opt-out is far cheaper than a block.
Reaching a large list before you are unlimited
If the list is larger than the tier, you have two honest options: spread the send over several days, or spread it across several registered numbers. Running one campaign across many numbers is supported by Meta and is how very large sends are cleared in a single day.
What does not work is trying to beat the limit with unofficial tooling. That is a WhatsApp policy breach and gets numbers banned rather than throttled.
