How to Send a WhatsApp Broadcast Message (2026 Step-by-Step)

A WhatsApp broadcast message is a single message sent to many recipients at once, where each person receives it as a normal, private one-to-one chat rather than a group thread. Nobody sees the other recipients, nobody can reply to the whole list, and replies come back to you individually. It is the WhatsApp equivalent of an email newsletter — one message, many private inboxes.

There are two completely different ways to send a broadcast on WhatsApp in 2026, and confusing them is the single biggest mistake businesses make:

1. Broadcast lists in the WhatsApp Business App — a built-in feature of the free mobile app, limited to small lists and contacts who have saved your number.
2. API broadcasts via the WhatsApp Business API — the method built for sending to hundreds or thousands of people using approved message templates, with delivery reports and no save-the-number requirement.

This guide explains both, shows you exactly when each one breaks down, and walks you step-by-step through sending a real broadcast at scale. If you only want a quick conceptual overview first, our explainer on broadcast vs campaign vs bulk breaks down the terminology.

The WhatsApp Business App's broadcast list feature is free and built in, but it has hard limits that make it unsuitable for serious marketing. You create a list, add contacts, and any message you send goes to everyone on it as an individual chat.

Here are the rules you must know before relying on it:

1. 256-contact cap per list. A single broadcast list can hold a maximum of 256 recipients. You can make multiple lists, but each is capped.
2. The "save your number" rule. A recipient only receives your broadcast if they have saved your business number in their phone's contacts. If they haven't saved you, your message silently never arrives. This alone kills most campaigns, because the vast majority of your customers have not saved your number.
3. No delivery analytics. You get the standard one or two ticks per chat, but no campaign-level report telling you how many delivered, read, or failed.
4. Manual and phone-bound. You send from your phone, one tap at a time, with no scheduling, no personalization at scale, and a real risk of your number being flagged for spam if you blast strangers.

Broadcast lists are fine for a tiny, loyal audience that has already saved you — say, 50 regulars at a salon. For anything larger or for reaching people who haven't saved your number, you need the API.

API broadcasts use the official WhatsApp Business API to send pre-approved message templates to large lists of contacts, regardless of whether those contacts have saved your number. This is how every professional WhatsApp marketing platform — including PayPerWA — sends bulk messages.

The key differences that make the API the right tool for scale:

1. No 256 limit and no save requirement. You can message thousands of contacts, and they receive the message even if they have never saved your number — as long as they opted in.
2. Template messages. To start a conversation (the broadcast scenario), you send a template that Meta has pre-approved. Templates can include variables like the customer's name, order ID, or offer code. See real examples in our WhatsApp template message examples guide.
3. Delivery reports. Every message returns a status — sent, delivered, read, or failed — so you get a true campaign report.
4. Compliance built in. Outbound marketing requires opt-in, and the template-approval system keeps your sender quality high so your number stays healthy.

The trade-off is that the raw API is developer-only. You either write code against Meta's Cloud API (we cover that in how to send bulk WhatsApp via API) or you use a platform like PayPerWA that gives you the API's power through a dashboard with contacts, templates, and a send wizard.

Here is the direct comparison so you can pick the right method in seconds.

If your answer to "do all my recipients have my number saved?" is no, the Business App is the wrong tool. Move to the API.

To send a WhatsApp broadcast to a large audience, connect your WhatsApp Business API number, import your opted-in contacts, pick an approved template, and launch the campaign. Here is the full walkthrough.

1. Create your account and connect WhatsApp. Sign up for PayPerWA and connect your number through the guided embedded signup — it links your WhatsApp Business API account in a few minutes, no developer needed. If you don't have a Business Account yet, the flow creates one.
2. Import your contacts. Upload a CSV of your opted-in contacts (name, phone with country code, and any custom fields like city or order ID). PayPerWA validates numbers and lets you tag and group them. You can also organize contacts into groups so you broadcast to a precise segment.
3. Confirm opt-in. Only message people who agreed to receive marketing from you — a checkbox at signup, a keyword they sent you, or a form submission. This is a hard rule, not a suggestion (more below).
4. Create or pick a template. Build a marketing template with your offer text and variables like {{name}}, then submit it to Meta for approval (usually minutes to a few hours). Or pick one from the pre-built library and customize it.
5. Map your variables. In the campaign wizard, map each template variable to a contact field so every recipient gets a personalized message — "Hi Rahul" instead of "Hi {{name}}".
6. Review the cost estimate. Before sending, PayPerWA shows the exact breakdown: number of contacts × (PayPerWA ₹0.20 + Meta's category rate). You see the total before you commit.
7. Recharge your wallet if needed. PayPerWA is prepaid — top up via UPI, card, or net banking so your balance covers the campaign.
8. Send or schedule. Launch immediately or pick a future date and time. Messages are queued and sent at WhatsApp's allowed rate so your number stays healthy.
9. Track the report. Watch live as messages move through sent, delivered, and read, with failures flagged. Failed messages are auto-refunded to your wallet.

That's a true broadcast — thousands of personalized, private messages, with a full report, and no one needing to have saved your number first.

You must have opt-in before sending any outbound marketing broadcast on WhatsApp — this is a Meta requirement, not optional. Sending unsolicited messages gets your number flagged, your quality rating dropped, and ultimately your account restricted.

Valid ways to collect opt-in:

1. Checkbox at checkout or signup stating the customer agrees to receive updates on WhatsApp.
2. A keyword opt-in — the customer messages you first (e.g. sends "JOIN" to your number) via a click-to-chat link or QR code.
3. A form or landing page where they enter their number and consent.

Good practice that protects your number: always offer an easy opt-out (a "reply STOP to unsubscribe" line), never buy contact lists, and keep your first marketing message relevant to why they signed up. WhatsApp rewards businesses that send wanted messages with higher messaging limits over time.

A WhatsApp broadcast costs PayPerWA's flat ₹0.20 per message plus Meta's own per-message charge, with no subscription. There is no monthly fee and no minimum — you pay only for what you send.

Meta's per-message charge depends on the message category. For India:

For international numbers, PayPerWA's fee is $0.004 per message and Meta's rate varies by country — see the full country rate card. A 1,000-contact marketing broadcast in India works out to roughly ₹1,060 all-in. Compare that with the per-message economics on our pricing page, and explore everything the platform does on features.
