WhatsApp Broadcast: Lists vs API Campaigns, Limits and Steps

Business app broadcast or API campaign: which should you use?

Use broadcast lists for a few hundred friendly contacts and occasional updates. Use API campaigns when you send promotions, need to reach people who have not saved your number, or want consent records, automation and reporting.

For the account-level differences, read WhatsApp Business API vs the Business app.

How do you send a broadcast list in the Business app?

Create a list, add contacts who have your number saved, and send. WhatsApp's menus differ slightly by phone, so use the app's own prompts.

1. Ask customers to save your business number. Say so on receipts, your website and your Instagram bio, and in your opt-in message.
2. Open the app's broadcast list option and create a new list.
3. Add up to 256 contacts. Add only people who agreed to hear from you.
4. Write a short, useful message with one action. Avoid sending the same offer repeatedly.
5. Send it, then handle replies as private chats.
6. Remove anyone who asks to stop, or who blocks you.

A QR code or link that opens a chat with a prefilled message helps customers start a conversation and save your number. Create one with our WhatsApp link generator or QR code generator.

How do you send a WhatsApp broadcast through the API?

Choose a provider, get your account verified, build the audience from opted-in contacts, get a template approved, and send in batches you can measure. A procedure:

1. Connect your number through a provider using Meta's Embedded Signup. See how to set up the WhatsApp Business API.
2. Build your audience from opted-in contacts. Meta requires opt-in: the person shared their number and agreed to messages from your named business, and you explain how to opt out. See opt-in and consent.
3. Create the template in the right category. An offer, recommendation or upsell is marketing; a message specific to a user's order or account can be utility. Meta may recategorise a template that does not fit.
4. Submit and wait. Meta says template review can take up to 24 hours.
5. Upload the list (CSV or Excel) and map variables such as first name.
6. Preview and test on your own numbers.
7. Schedule for local daytime and send in batches within your messaging limit.
8. Watch delivery, read rate, replies, opt-outs and template quality. Pause if quality drops.
9. Answer replies within the 24-hour window and follow up only with people who engaged.

Template pacing matters on new or lower-rated templates: Meta may release the first part of a send, wait for early feedback, and hold or drop the rest if the signals are negative. Start with your most engaged segment.

What mistakes get a WhatsApp number restricted?

WhatsApp can limit or remove access for significant negative feedback or policy breaches. These are the usual causes.

• Sending to people who never opted in. Purchased and scraped lists produce blocks and reports.
• Using unofficial bulk tools on a normal number. WhatsApp prohibits unauthorised automated or bulk messaging on its apps.
• Sending irrelevant or too frequent promotions. Low read rates and blocks lower quality and trigger per-user caps.
• Mislabelling marketing as utility. Meta can recategorise templates and escalate enforcement for repeated misclassification.
• Ignoring opt-outs and "Not interested" feedback. People can also stop marketing messages from your business inside WhatsApp.
• Retrying capped messages at once. After error 131049, wait at least 24 hours.

How much does a WhatsApp broadcast cost?

Broadcast lists are a feature of the app and are not billed through the Business Platform. API template messages are billed by Meta per delivered message, by category and by recipient country; marketing is a paid category. We pass Meta's charge through at Meta's rate with zero markup, and BroadNet charges no setup fee and no monthly minimum.

For numbers, use our WhatsApp pricing by country and the pricing calculator, and confirm in Meta's current rate card. Business broadcasts with message credits have their own pricing inside the app.

Worked example: a Riyadh fitness studio

A synthetic studio, "Najd Fit", has 1,800 members. Its owner starts with a Business app broadcast list: 256 members per list means eight lists, and members who never saved the studio's number miss the message. After a few weeks the owner cannot tell who read the timetable change.

The studio moves to an API campaign. It imports 1,800 members who opted in at sign-up, gets one utility template approved for timetable changes and one marketing template for the new-term offer, and sends the offer in two batches under its messaging limit. Delivered, read and reply statuses show who engaged, and members who reply "stop" are suppressed. The change is not the list size; it is that every send has consent, a template and a record.
