WhatsApp quality rating and messaging limits, explained

Updated 2026-09-24 · 5 min read · By the Convo360 team

What quality rating actually measures

Meta assigns each business phone number a quality rating of high, medium or low, shown in Business Manager. It is not a measure of your content or your intentions. It is a measure of how recipients respond.

Blocks weigh heaviest. Reports weigh heavily. Messages that go unread over a long period contribute. Positive engagement, meaning people replying and reading, holds the rating up.

This is why two businesses sending identical volumes can have completely different ratings. One is messaging people who asked to hear from them about things they care about; the other bought a list.

The rating is a rolling window, so it reflects recent behaviour rather than your history. That cuts both ways: a bad campaign hurts quickly, and a recovery is possible within weeks.

One consequence surprises people: a number can have a low rating while its owner has done nothing obviously wrong. A single poorly targeted campaign to a large list is enough, because the rating reflects a proportion of recipients rather than an absolute count of complaints.

How messaging limits work

Separately from quality, each number has a messaging limit: how many unique customers you can start a conversation with in a rolling twenty-four hours.

Limits rise automatically when you send consistently at a healthy quality rating. They fall when quality drops. Note that the limit counts business-initiated conversations only; customers writing to you are not restricted at all.

Most Indian small businesses never encounter the limit. It becomes relevant the first time you run a real broadcast campaign, which is also when quality is most at risk.

Verification matters at the start. A business that has completed Meta's verification begins at a higher limit than one that has not, which is worth doing before your first campaign rather than discovering the cap halfway through it.

What actually drops a rating

In order of how often it causes problems for Indian businesses:

• Broadcasting to an unsegmented list. Sending a jewellery offer to everyone who ever wrote about a delivery is the fastest route to blocks.
• Messaging people who did not really opt in. A number collected at a counter two years ago is not consent to receive marketing today.
• Too much, too often. Weekly promotional messages to the same list wear out quickly.
• Messages with no value. Festival greetings from a brand somebody bought from once are mostly noise.

The common thread is relevance. Meta is effectively measuring whether recipients wanted the message, and recipients are unforgiving.

What to do when the rating drops

Treat it as an alarm that needs action the same day.

Stop all marketing broadcasts immediately, before analysing anything. Then look at what you sent in the preceding seventy-two hours and identify the campaign responsible, which is usually obvious.

Do not respond by sending more, and do not switch to a new number to escape the rating. Meta tracks businesses, not just numbers, and a pattern of abandoning numbers is itself a signal. Recovery on the existing number, by sending less and better, is faster in practice.

Service conversations, where customers write to you, are safe to continue and actively help. Genuine engagement is exactly what pulls a rating back up.

Tell your team what happened, in plain terms. Quality drops are usually caused by a decision somebody made with good intentions, such as messaging the full list because a sale was underperforming. If the reason is never explained, the same decision gets made again next quarter.

How Convo360 helps you avoid it

Convo360 paces broadcast campaigns rather than firing everything at once, with speed presets and a daily cap set as a proportion of your current tier, so a campaign cannot push you past your own limit.

If Meta signals a spam or quality problem mid-campaign, the broadcast pauses automatically, keeps the remaining numbers queued, and retries on a backoff rather than continuing into a wall. A failure breaker stops a campaign that is failing consistently instead of burning your rating on a broken template.

Contacts, consent records and tags live alongside the campaign tool, so segmenting by what somebody actually asked about is a filter rather than a spreadsheet exercise. That is the single most effective protection there is. The campaigns docs cover the controls in detail.

Building the habit that keeps quality high

Three rules cover almost everything.

Segment every marketing send by something the recipient did, not by everyone you have. Send less often than you think you should. And make utility messages, which people genuinely want, the majority of what you send.

Watch the rating weekly rather than after a campaign. A drift from high to medium is far easier to reverse than a drop to low, and the early signal is usually a rising block rate on one segment rather than across the board.

Finally, resist the temptation to judge a campaign only by orders. A broadcast that produced sales and cost you a tier is a bad trade, because the tier affects everything you send for months afterwards.

Keep a simple record of every broadcast: which segment, how many, what template, and the rating before and after. Three months of that turns quality management from guesswork into something you can reason about, and it is the fastest way to find out which kind of message your particular audience tolerates.
