Messaging limits and tiers, and how to move up them

Your messaging limit is the number of unique customers you can start a conversation with in a rolling 24 hours. It is a cap on how many people you reach, not on how many messages you send — replying inside an open conversation does not count against it at all.

New business portfolios start at 250. That surprises merchants who have just imported a list of 5,000 contacts, and it is the reason a first campaign so often reaches a fraction of the intended audience.

The five tiers

These come from Meta's messaging limits documentation.

Getting from 250 to 2,000

Meta gives three routes, and one of them is far faster than the others:

1. Verify your business. The fastest deliberate route — you control the timing, and it multiplies your reach eightfold.
2. Have a partner verify it. An alternative path to the same place.
3. Earn it by sending. Deliver 2,000 messages to unique users outside customer service windows within a 30-day moving period, using high-quality templates. Slow, and it requires you to already be sending at volume.

If you are planning a launch or a seasonal campaign, start business verification weeks ahead. It takes days rather than minutes, and arriving at your busiest trading day capped at 250 recipients is a self-inflicted wound.

Moving up from 2,000

Above tier 2 the mechanism changes and becomes automatic. Meta raises you one level within 6 hours when two things are true at once: you have used at least half your current limit within a 7-day period, and your message quality stays high.

The "half your limit in 7 days" condition is the one people miss. A store that sends in occasional bursts and then goes quiet may never trigger an increase, regardless of quality, because it never reaches the usage threshold.

What the limit does not cover

Three separate systems get confused with each other constantly, and the fix for each is different.

Meta's tier documentation explicitly notes that it does not cover quality-rating-based limits, which are a separate mechanism. And the per-user marketing cap is a different thing again — an adaptive limit with no published number that applies to what the recipient receives, not what you send.

What happens when you hit the ceiling mid-send

The send does not fail loudly. Recipients beyond your limit simply are not reached in that 24-hour period. If a campaign to 5,000 people delivered to roughly 2,000 and stopped, your tier is the first thing to check — before you start investigating template quality or phone numbers.

Practically, this means a large list should be sent in planned batches sized to your tier rather than fired at once. Our broadcast-side guide to limits and tier caps covers the sending mechanics.

Design around the limit, not against it

The most effective response to a low tier is not to fight it but to lean on conversations you did not have to start. Replies inside an open window are uncapped, so a store whose customers message it — from a Click-to-WhatsApp ad, a website button, a QR code on the packaging — operates with far more headroom than one that broadcasts outward.

That is the same conclusion as the cost article reaches from a different direction: inbound conversations are both free and uncapped, and outbound ones are neither.

Before your next big send

1. Check your current tier.
2. If it is 250 and you have not verified your business, start that now.
3. Size the batch to the tier, rather than sending and hoping.
4. Check your quality rating is green, since a downgrade blocks increases.
5. Send to people who engage — it protects quality and the tier that depends on it.
