A WhatsApp broadcast message lets you send the same message to up to 256 contacts at once, delivered as individual chats so recipients cannot see each other. It is free, built into both WhatsApp and WhatsApp Business, and works on Android and iPhone. However, all 256 recipients must have your number saved in their contacts, there is no scheduling or automation, and high-volume sending risks triggering spam detection. Below is a complete guide to sending broadcasts, understanding the limits, and deciding when to upgrade to the WhatsApp Business API.
What Is a WhatsApp Broadcast Message?
Note
A WhatsApp broadcast message is a one-to-many messaging feature. You send one message to multiple contacts simultaneously without creating a group. Each recipient receives it as a private, individual chat and cannot see who else received the same message.
This feature is useful for individuals who need to contact multiple people at once and for businesses sending updates, promotions, or announcements. Many small businesses use broadcast lists because they are free, simple, and require no technical setup.
However, broadcast messages have hard limits that growing businesses will hit quickly. Understanding these limits before adding broadcasts to your workflow prevents wasted effort and potential account bans.
How to Send a Broadcast Message on WhatsApp
The steps differ slightly between Android and iPhone. Both WhatsApp and WhatsApp Business support broadcast lists.
1. On Android
- Open WhatsApp and tap the three-dot menu in the top-right corner.
- Select New broadcast.
- Search or scroll to select up to 256 contacts. Only contacts who have saved your number will receive the message.
- Tap the green checkmark to create the broadcast list.
- Type your message, attach media if needed, and tap Send.
2. On iPhone
- Open WhatsApp and go to the Chats tab.
- Tap Broadcast Lists at the top of the screen.
- Tap New List.
- Select up to 256 contacts and tap Create.
- Type your message and send. Each recipient sees it as a private 1:1 chat.
3. On WhatsApp Business App
The WhatsApp Business app follows the same broadcast steps as the personal app but adds two business-specific features:
- Label-based filtering: Select contacts by label (e.g., "New Customers" or "VIP") when building a broadcast list.
- Quick replies and catalog links: Insert saved quick replies or product catalog links directly into your broadcast message.
The Business app is free and suitable for small businesses with fewer than 256 contacts per campaign. Beyond that, the WhatsApp Business API is the official path for scaling.
WhatsApp Broadcast Message Limits Every Business Should Know
WhatsApp broadcast messages have five hard limits that affect how businesses can use them:
- 256 contacts per list: Each broadcast list supports a maximum of 256 recipients. To reach more people, you must create and manage multiple lists manually.
- Recipient must save your number: If a contact has not saved your phone number, they will not receive your broadcast. There is no way to bypass this requirement.
- Spam detection risk: Sending high volumes of identical messages or promotional content from a personal account can trigger WhatsApp spam filters, leading to temporary restrictions or a permanent ban.
- No scheduling or automation: Broadcasts must be sent manually. There is no built-in way to schedule messages, set up drip sequences, or trigger automated follow-ups.
- No analytics: WhatsApp provides blue double-check marks for read receipts, but no delivery rate, open rate, or click tracking at the campaign level.
Is a Personal Account Safe for Business Broadcasts?
Using a personal WhatsApp account for commercial broadcasts violates the WhatsApp Terms of Service (Section 4: Acceptable Use). WhatsApp explicitly prohibits using personal accounts for bulk or automated messaging. The risks include:
- Account temporarily restricted or permanently banned
- Phone number flagged as spam across WhatsApp
- No access to business-grade security features (two-step verification for business, encrypted backups)
- No compliance with data protection regulations (GDPR, PDPA) that require audit trails
For any business sending promotional or transactional messages at scale, the WhatsApp Business App (free) or WhatsApp Business API (paid, through a BSP) is the compliant path.
Broadcast List vs. Group Chat vs. WhatsApp Business API
These three WhatsApp features serve different purposes. Choosing the wrong one wastes time and limits your reach.
| Capability | Broadcast List | Group Chat | Business API |
|---|---|---|---|
| Delivery | Private 1:1 chat | Public to all members | Private 1:1 chat |
| Contact Limit | 256 per list | 1,024 members | Unlimited |
| Recipient Requirement | Must save your number | Must join group | Must opt in (template-based) |
| Automation | Not supported | Not supported | Full workflow automation |
| Analytics | Read receipts only | None | Delivery, read, click tracking |
| CRM Integration | None | None | Native CRM/ERP integration |
| Message Types | Text, image, video | Text, image, video | Templates, buttons, carousels, catalog |
| Compliance Risk | High (if used commercially) | Moderate | Fully compliant (Meta-approved) |
| Cost | Free | Free | Per-conversation pricing ($0.005-$0.15 by region and category) |
| Best For | Small teams, <256 contacts | Community discussions | Businesses scaling beyond 256 contacts |
Quick decision rule: If you need to message fewer than 256 contacts who already have your number saved, a broadcast list works. If you need automation, analytics, CRM integration, or unlimited contacts, the WhatsApp Business API is the right tool.
When and How to Scale with WhatsApp Business API
The WhatsApp Business API is Meta's official solution for businesses that have outgrown native broadcast lists. Unlike the free WhatsApp or WhatsApp Business apps, the API requires setup through a Business Solution Provider (BSP) such as EngageLab, Twilio, or WATI.
With the API, your business can:
- Send approved templates at scale: Marketing, utility, and authentication templates with no contact limit.
- Automate customer journeys: Trigger messages based on user actions (abandoned cart, order shipped, appointment reminder).
- Integrate with existing systems: Connect WhatsApp to your CRM, ecommerce platform, or helpdesk.
- Track campaign performance: Monitor delivery rate, read rate, and link clicks in real time.
- Stay compliant: All messages go through Meta-approved templates, reducing ban risk to near zero.
Getting Started with WhatsApp Business API
Step 1: Register a WhatsApp Business account. Verify your business through Meta Business Manager. This confirms your identity and unlocks API access.
Step 2: Connect through a BSP. A Business Solution Provider like EngageLab handles the technical setup: number connection, webhook configuration, and security controls. This eliminates the need for in-house API development.
Step 3: Create and submit message templates. All outbound marketing and utility messages require Meta approval. Templates support rich media, interactive buttons, and dynamic variables (customer name, order number, etc.).
Step 4: Launch, monitor, and optimize. Track delivery rates, read rates, and click-through rates per campaign. Use A/B testing to refine message timing, content, and audience segments.

WhatsApp Broadcast Message FAQ
How many contacts can I add to a WhatsApp broadcast list?
Each broadcast list supports a maximum of 256 contacts. You can create multiple broadcast lists, but each must be managed and sent to separately. There is no way to increase the 256 limit within WhatsApp or WhatsApp Business.
How do I send a broadcast message on WhatsApp iPhone?
Open WhatsApp, go to the Chats tab, tap "Broadcast Lists" at the top, then tap "New List." Select up to 256 contacts, tap "Create," type your message, and send. Each recipient receives it as a private chat.
How do I know if my broadcast message was delivered?
WhatsApp shows standard delivery indicators: one gray checkmark means sent, two gray checkmarks mean delivered, and two blue checkmarks mean read. However, these are per-contact indicators. There is no aggregated delivery report or campaign-level analytics in native broadcast lists.
What is the difference between a WhatsApp broadcast and a group?
A broadcast list sends your message as a private 1:1 chat to each recipient. No one can see other recipients or their replies. A group chat is a shared space where all members see every message. Broadcasts are better for announcements; groups are better for discussions.
Can WhatsApp ban me for sending broadcast messages?
Yes. If you send high volumes of promotional or identical messages from a personal account, WhatsApp may flag your number as spam. This can result in temporary restrictions or a permanent ban. Using the WhatsApp Business App or WhatsApp Business API reduces this risk significantly because these tools are designed for commercial messaging and follow Meta's compliance guidelines.
How much does WhatsApp Business API cost?
The WhatsApp Business API uses per-conversation pricing set by Meta. Rates vary by country and message category: utility conversations range from $0.005 to $0.08, and marketing conversations range from $0.02 to $0.15. BSP providers like EngageLab may add a platform fee or offer bundled pricing. Service conversations (user-initiated) are free for the first 1,000 per month.
Can I schedule a WhatsApp broadcast message?
Native WhatsApp and WhatsApp Business do not support message scheduling. To schedule broadcasts, you need the WhatsApp Business API connected through a BSP, which provides scheduling, automation, and campaign management features. For more on automating WhatsApp messages, see our WhatsApp marketing automation guide.
Bottom Line
WhatsApp broadcast messages are a fast, free way to reach up to 256 contacts privately. For small teams and personal use, they work well. For businesses that need to message larger audiences, automate follow-ups, track campaign performance, or stay compliant with WhatsApp commercial policies, the WhatsApp Business API is the official upgrade path.
Evaluate your current contact list size, messaging frequency, and compliance requirements. If you are regularly hitting the 256-contact limit or managing multiple broadcast lists manually, it is time to explore API-based solutions.
