Quick answer
WhatsApp messaging limits cap how many unique customers a business can send messages to outside open customer service windows in a rolling 24 hours. Limits are set per Meta business portfolio, start low, and rise in steps when the business is verified and keeps sending well-received messages. The quality rating reflects recent customer feedback such as blocks and reports; low quality pauses templates and stops limits from growing.
Key takeaways
- The limit counts unique customers you message outside open service windows in 24 hours, not total messages.
- Since 2025 the limit belongs to your Meta business portfolio and is shared by all its phone numbers.
- New businesses start on a low tier; business verification and good-quality sending unlock higher tiers.
- Replies to customers who messaged you within the last 24 hours do not use up your limit.
- Quality is driven by how customers react: blocks, reports and complaints pull it down.
WhatsApp messaging limits are the maximum number of unique customers a business can message, outside an open customer service window, within a rolling 24-hour period. Together with the quality rating, they are how Meta lets trustworthy businesses scale while slowing down anyone who spams.
This explainer is for owners and marketers planning broadcasts, reminders or campaigns on the WhatsApp Business API. It covers how the tiers work, how a new business moves up, what the quality rating measures and what to do when it drops. Meta has changed these rules more than once, so treat the numbers here as a guide and confirm the current figures in Meta's messaging limits documentation.
What are WhatsApp messaging limits?
A messaging limit is a daily ceiling on the number of different people your business can reach with messages they did not just ask for, which in practice means template messages to customers who have not written to you in the last 24 hours. Sending three templates to the same customer counts once.
Customers who message you first are not limited. If 5,000 people write to your shop in a day, your team can reply to all of them, because each reply happens inside an open customer service window. Limits only bite when you start conversations, as with broadcasts, reminders and follow-ups.
What are the messaging limit tiers?
Meta's documentation, as of October 2026, describes these steps. Check it before planning a large send, as the figures have changed over time.
| Tier | Unique customers per 24 hours | How you reach it |
|---|---|---|
| Starting tier | 250 | New business portfolios start here |
| Second tier | 2,000 | Complete a scaling path, such as business verification |
| Higher tiers | 10,000, then 100,000 | Automatic increases with high quality and enough usage |
| Top tier | Unlimited | Automatic, after sustained high quality at 100,000 |
You can see your current limit in WhatsApp Manager under Account tools, in the messaging limits panel. If you use a provider such as chat.or.ke, ask them to check it for you.
Why are limits set per business portfolio?
Meta moved messaging limits from individual phone numbers to the business portfolio in 2025. All the WhatsApp numbers in one portfolio now share one limit.
This matters for businesses with several numbers. If a Nairobi retailer has a sales number and a support number in the same portfolio, a big promotion from the sales number uses up capacity the support number might need for delivery updates that day. Plan big sends around your operational messages, or send updates first.
How do you increase your WhatsApp messaging limit?
Get to the second tier through a scaling path, then let automatic scaling do the rest. Meta lists several ways to move off the starting tier:
- Verify your business with Meta, using your registration certificate, KRA PIN and proof of address. Our guide to verifying your business on Meta walks through it.
- Partner verification, where the provider that onboarded you vouches for your business.
- Sending volume: delivering a set number of good-quality messages outside service windows to unique customers within a set period.
After that, Meta raises the limit one step at a time when two things are true: your messages are high quality across your numbers and templates, and you have used at least half of your current limit in recent days. Increases usually take effect within hours.
On chat.or.ke, setup includes creating your Meta business profile and submitting it for verification, so you start on the right path.
What is the WhatsApp quality rating?
The quality rating is Meta's assessment of how customers have received your recent messages, shown as high, medium or low (green, yellow or red) in WhatsApp Manager. It is driven by customer signals such as blocks, reports and the reasons people give when they block.
Templates have their own quality too. A template that reaches low quality is paused automatically: for a few hours the first time, longer the second time, and disabled after repeated problems, according to Meta's template pausing rules. Other healthy templates keep working, but a business whose templates keep falling to low quality can see its phone number affected.
What happens when quality drops?
A falling rating is a warning. At medium you can usually keep sending, but your limit is unlikely to grow. At low, templates may be paused, automatic scaling stops and repeated problems can lead to restrictions on the number.
Meta's exact consequences have changed over the years, including how and whether limits are reduced, so check the current documentation if your rating turns red. The fix is the same regardless: stop the messages causing complaints.
What lowers your quality rating?
Almost always, sending messages people did not expect or want.
| Cause | What to do instead |
|---|---|
| Messaging contacts who never opted in | Build a genuine opt-in list |
| One promotion to your entire list | Segment by interest, location or purchase history |
| Promotions too often | Space them out and make each one worth reading |
| No way to stop | Add "Reply STOP" or a stop button |
| Vague, salesy templates | Name your business and give a clear reason for the message |
| Sending at night | Send during reasonable hours |
Worked example: a Nairobi electronics shop
An electronics shop on Luthuli Avenue moves from the WhatsApp Business app to the API. It has 3,000 past customers and wants to announce a phone sale on its first day.
On the starting tier it can only reach 250 unique customers outside service windows in 24 hours. Sending to all 3,000 in one go is not possible, and trying to reach the least engaged first would risk blocks.
Instead, the shop completes Meta business verification during setup, then sends the sale only to the 250 customers who opted in most recently and bought in the last six months. Replies come in, the quality rating stays high, and over the following weeks the shop works through the rest of its opted-in list in segments. As its limit rises, it can reach more people each day. chat.or.ke broadcasts pace sends to stay within WhatsApp's limits and filter out contacts who opted out, keep failing or were messaged too often, which makes this approach easier to run.
How do you protect your rating long term?
Treat every broadcast as a test of whether customers want to hear from you. Check sent, delivered, read and failed counts after each send, watch opt-outs, and pause if blocks rise. Our guide on sending WhatsApp broadcasts without getting blocked covers the habits in detail, and why WhatsApp business numbers get banned explains what happens in the worst cases.
