Almost every "WhatsApp broadcast limit" article in India quotes the same number: 256. It's correct — and it's the wrong number for any business serious about marketing, because 256 is the cap on the free WhatsApp Business App, not the WhatsApp Business API that real broadcast software uses.
If you're planning campaigns, you need to understand the API model instead: it isn't a fixed cap, it's a system of messaging tiers governed by your quality rating.
The App cap vs the API model
WhatsApp Business App (the free phone app):
- Broadcast lists are capped at 256 contacts.
- Recipients only get the message if they've saved your number.
- One device, no automation, no segmentation. Fine for a tiny shop; a dead end for marketing at scale.
WhatsApp Business API (via a BSP):
- No fixed 256 cap. Volume is governed by your messaging tier.
- Reaches any opted-in contact using approved templates.
- Multi-agent, automated, segmented — built for scale.
The jump from App to API is the jump from "message my saved contacts" to "run campaigns to thousands of opted-in customers." For the full comparison, see WhatsApp Business API vs App.
Messaging tiers: how volume actually scales
On the API, a number sits in one of four tiers, defined by how many unique customers you can start a conversation with per rolling 24 hours:
| Tier | Unique 24-hour conversations |
|---|---|
| Tier 1 | 1,000 |
| Tier 2 | 10,000 |
| Tier 3 | 100,000 |
| Tier 4 | Unlimited |
New numbers start at Tier 1. Meta promotes you automatically as you send within policy and keep a high quality rating — there's no form to fill, you earn the tier by behaving well. Crucially, the limit is on unique conversations initiated, not total messages, and replies inside the 24-hour service window don't count against it.
Quality rating: the real governor
Your number carries a quality rating — Green (high), Yellow (medium), or Red (low) — based on recent recipient feedback: blocks, reports, and how people engage. It's the lever that actually controls your sending:
- A high rating lets tiers scale up.
- A Red rating can drop your tier or restrict the number entirely.
This is why blasting a purchased list is self-defeating: even if the send goes out, the blocks and reports tank your rating, and Meta throttles the number. One bad campaign can cost you the channel. (See the quality rating glossary entry for the mechanics.)

The practices that keep your number healthy and growing:
- Only message opted-in contacts. Capture explicit, purpose-specific consent — required under DPDPA 2023 anyway — and record the source and timestamp, not just the number.
- Segment instead of blasting. Send relevant content to the right list. Relevance drives engagement, which protects the rating.
- Throttle large sends. Pace a big campaign rather than firing it all at once, so a spike of blocks doesn't trip a downgrade. Good broadcast software does this for you.
- Honour opt-outs instantly and automatically. A frictionless opt-out lowers reports, which protects the rating.
- Watch the quality rating live. Treat a slide from Green to Yellow as an early warning, not a problem to ignore.
WatEase enforces these by default — opt-in capture, automatic opt-out handling, quality-aware throttling, and live rating monitoring — so a growing list never costs you the number. And because broadcasts tie into a catalog and in-chat UPI checkout, a compliant send can end in a measured order rather than just a read receipt.
The takeaway: stop thinking about WhatsApp broadcasting as a number you're allowed to send. Think about it as a reputation you maintain — send to people who asked, keep them engaged, and the limits lift themselves.
