A new number cannot message everyone immediately. There is a ceiling on how many distinct people you can start conversations with in a rolling 24 hours, it starts low, and it moves in response to behaviour rather than to effort.
How the tiers work
Limits are counted as unique recipients you initiate business-conversations with per rolling 24 hours. The usual ladder runs 250, then 1,000, then 10,000, then 100,000, then unlimited. Replies to people who messaged you first do not count against it.
The distinction matters: a support-heavy business answering inbound messages can operate happily at the lowest tier indefinitely. The limit only bites when you initiate.
What actually moves you up
Two conditions, together: your quality rating must be acceptable, and you must actually approach your current limit. Sending 40 messages a day at a 250 cap will not promote you, because the system has no evidence you need more.
- Send consistently, to people who want to hear from you.
- Keep quality at medium or high — a low rating freezes progression and can lower your limit.
- Be verified. Unverified numbers hit a ceiling regardless of behaviour.
- Give it days, not hours. Evaluation is periodic.
The counter-intuitive bit
Buying a list and sending to all of it to "prove volume" does the opposite of what people expect. Blocks and reports from strangers drop quality, and a low quality rating stops progression outright. The fastest route to a higher tier is a smaller, genuinely opted-in audience that replies.
Planning around a low limit
- Prioritise. At 250 a day, spend them on messages that matter — order updates, appointment reminders — not on a general promotion.
- Stagger. A 900-person campaign at a 250 cap is four days. Plan it as four days rather than discovering it mid-send.
- Warm up deliberately. Start with your most engaged contacts. Early replies and low block rates are exactly the signals that raise both quality and tier.
- Use free entry points. Conversations customers start from a click-to-WhatsApp ad or a website button do not consume initiated capacity.
If your limit goes down
Limits can be reduced when quality falls. It is a symptom, not the disease. Look at what you sent in the preceding days: a broadcast to an old list, a message people did not expect, a template whose content did not match its category. Fix the cause and quality recovers over days.
Pausing outbound entirely for a short period while you fix targeting is usually faster than continuing to send and hoping the average recovers.
A realistic timeline
A verified business sending genuinely wanted messages to an opted-in list typically moves off the lowest tier within a couple of weeks and reaches the 10,000 tier within a month or two. Businesses that start by importing a purchased list frequently never get past the first tier, because the early damage to quality is hard to undo.
The first fortnight matters disproportionately. Spend it on people who will be pleased to hear from you.
