WhatsApp quality rating and messaging limits: how to grow from 250 to unlimited without Meta throttling you

Anyone who moves from the free WhatsApp Business App to the Cloud API trades an invisible rule for two visible dials. In the app you never know how close you are to a block; why WhatsApp Business gets blocked there is covered in the first article of this series. On the API, Meta, the parent company of WhatsApp, does show you: a quality rating (also called quality score) that says how your messages are received, and a messaging limit that says how many people you may approach per day.

The two are connected. A good rating lets your limit grow, from 250 contacts a day up to unlimited. A poor rating brings it down. Anyone who understands how Meta turns those dials can plan campaigns without surprises and grows within a few weeks to a reach the free app never gets near.

The messaging limit is the number of unique contacts you as a business may start a conversation with in a rolling period of 24 hours. Three things make that number different from what it looks like:

• Only conversations you start count. A customer who messages you and whom you reply to costs you nothing from your limit. Only template messages you send first are counted.
• Unique means unique. Send the same customer three messages today and that counts as one contact.
• The limit applies per business portfolio at Meta, not per phone number. Since October 2025 all WhatsApp numbers in the same portfolio share one limit. Requesting an extra number therefore gives you no extra room.

Meta has five tiers. Every new account starts at the bottom and grows based on behaviour:

1. 1250 unique contacts per 24 hours. The starting tier for every new number. Enough to test and approach your first opt-ins, too little for a campaign to your customer base.
2. 22,000 per 24 hours. You get this tier as soon as Meta has verified your business. Business verification is therefore the fastest step you can take yourself.
3. 310,000 per 24 hours. From here Meta raises the limit automatically, based on your quality and your usage.
4. 4100,000 per 24 hours. For companies with a large, active base and a consistently good rating.
5. 5Unlimited. No daily ceiling any more; only your quality rating still counts.

Above 2,000 you do not have to request anything. Meta raises your limit by itself as soon as you meet three conditions at the same time:

• Your quality rating is good, across all numbers and templates in your portfolio together.
• You use your current limit actively. In the past seven days you have used at least half of your limit, without receiving negative feedback.
• Your account is in order. Your number is verified and your display name is approved.

The second condition often comes as a surprise. Anyone who plays it safe and sends only a few hundred messages a week on a limit of 2,000 stays at 2,000. Growing therefore asks for structural sending, at a pace your customers are comfortable with. That is why we plan a build up with customers: a little more every week, only to contacts with an opt-in, and the next step only once the rating stays green.

The quality rating is not a mark for your texts, but for how your contacts reacted in the past seven days. Meta looks at:

• contacts who block you or report you as spam;
• contacts who mute or archive the conversation;
• the reason someone gives when blocking you.

Recent signals weigh more heavily than older ones. What does not count: how many messages were delivered or read. A campaign with a high read rate but ten blocks scores worse than a small, targeted campaign without complaints.

Meta expresses the rating in three colours: green (high quality), yellow (medium) and red (low, many complaints). In CommuniQate you see it as a word, for example High, with a note on whether action is needed. Because the window is seven days, a rating also recovers quickly once you adjust.

Meta works in steps, and every step is a chance to adjust:

1. 1The rating turns red. Your number gets the status Flagged at Meta. If the rating improves within seven days, the status goes back to Connected and nothing else happens.
2. 2The rating stays red for seven days. Meta lowers your messaging limit by one tier straight away. Going from 10,000 back to 2,000 means your next campaign suddenly has to run over five days instead of one.
3. 3The complaints keep coming. Your number gets the status Restricted and your WhatsApp Business is restricted: you temporarily cannot start new conversations. Replying to customers who message you keeps working as usual. You can see the current status of your number in Meta Business Manager, and that is also the place where you can reach Meta support yourself.

Besides your account, every WhatsApp message template has a quality status of its own. If one template gets a lot of complaints, Meta pauses that template: three hours the first time, six hours the second time, and the third time it is switched off for good. Your account simply carries on, but that one campaign comes to a standstill.

A green rating is not luck but routine. These are the habits we keep seeing with customers on the unlimited tier:

1. 1Only contacts with a recorded opt-in. People who gave permission themselves rarely block you.
2. 2Segmenting instead of everyone. Send a promotion to the people it is useful for, not to your whole base.
3. 3A fixed, predictable frequency. One relevant message a week holds attention; three a day gets you muted.
4. 4Utility where it is utility. Confirmations, reminders and updates as a service message, not dressed up as a promotion. That is cheaper and gets fewer complaints.
5. 5Make unsubscribing easy. A button or a word like "stop" in every marketing message. An unsubscribe costs you nothing; a block costs you your rating. How to organise that neatly is covered in our article on WhatsApp opt-in and GDPR.
6. 6Test new templates small. First to a few hundred contacts, then scale up if the rating stays stable.
7. 7Look every week. One glance at your dashboard a week is enough to spot a downward trend before Meta steps in.

Once your limit is full, you cannot approach any new unique contacts until the end of the rolling 24 hours. Existing conversations and replies to customers who message you simply carry on. This is how you plan around it:

• Split large campaigns up. A base of 6,000 contacts on a limit of 2,000 goes out over three days, with the most engaged segments first.
• Apply for business verification if you are still on 250. That is the fastest route to 2,000.
• Check where you stand before every large send. In CommuniQate you see your current limit and rating on the Dashboard, in the WhatsApp account block, and under Channels with your WhatsApp account. With Sync with WhatsApp you fetch the latest state from Meta.

That way a limit becomes not a wall but a planning detail.
