TL;DR
- A WhatsApp broadcast sends one message to many people at once, but each person receives it as a private one-to-one chat, so it feels personal, not like a group blast.
- There are two very different versions: the free WhatsApp Business app "broadcast list" (capped at 256 contacts who already saved your number) and broadcasts through the WhatsApp Business Platform (approved templates, opt-in, and real scale). Business broadcasting means the second one.
- WhatsApp gets read. The honest, measured open rate is around 60 to 68 percent, not the "98 percent" you see quoted everywhere, and still far ahead of email.
- Since July 1, 2025, you pay per message, priced by category and country. Opt-in is mandatory, and your quality rating decides how many people you can reach.
- Done right, with segmentation, personalization, and two-way replies, broadcasts become your highest-converting channel. Done wrong, they get you blocked.
One broadcast, many private one-to-one chats. That is what makes WhatsApp broadcasts feel personal at scale.
What is a WhatsApp broadcast?
A WhatsApp broadcast lets you send the same message to many contacts at once, while each recipient sees it as a normal private chat. No one sees the other recipients, and anyone can reply directly to you. That single detail is why broadcasts feel like a conversation instead of an ad.
The confusion starts because "WhatsApp broadcast" means two different things:
- The free app broadcast list. Built into the WhatsApp Business app. It is capped at 256 recipients per list, and it only reaches people who have saved your number in their phone. There are no real analytics and no way to scale. It is fine for a single small shop messaging its regulars.
- Broadcasts through the WhatsApp Business Platform. This is the official business route, used through a provider like Invent. You send approved template messages to customers who have opted in, you can reach tens or hundreds of thousands of people, and you get delivery, read, and reply analytics. This is what "WhatsApp broadcast marketing" actually means at business scale.
Broadcast list versus WhatsApp Business Platform: same channel, very different reach.
If you are comparing tools or planning real campaigns, you want the Platform version. The rest of this guide focuses there.
Do WhatsApp broadcasts actually work? The honest numbers
You will see "95 to 98 percent open rates" repeated across the internet. Be skeptical. The credible, measured open rate for WhatsApp campaigns sits around 60 to 68 percent, with Braze reporting 68 percent across its customer base. That is the number to plan with, and it still beats email by a wide margin.
For context in 2026:
- Open rate (2026): about 60 to 68 percent on WhatsApp broadcasts (measured) versus about 20 to 25 percent on email.
- Click rate (2026): about 15 to 25 percent on WhatsApp broadcasts versus about 2 to 3 percent on email.
- Best for: WhatsApp for high-intent, time-sensitive messages; email for long-form, low-cost bulk.
So WhatsApp typically delivers three to five times the engagement of email, even at conservative measured benchmarks. The reason is simple: people keep WhatsApp open all day, they trust it, and a broadcast lands in the same thread where they already talk to friends and family. That trust is also why the WhatsApp business economy now runs into the tens of billions of dollars. Vendors also report strong e-commerce returns (often quoted at 15 to 60 times campaign cost), though those figures vary by sender, so treat them as directional, not guaranteed.
How many people can you send a WhatsApp broadcast to?
It depends on which version you use. The free WhatsApp Business app caps each broadcast list at 256 contacts, but there is no limit on how many lists you can create, so ten lists of 256 reach 2,560 people from one number. Treat that cap as a nudge toward targeted lists, not a ceiling on your audience.
The WhatsApp Business Platform removes the list cap entirely and replaces it with a messaging tier system. It limits how many unique customers you can message in a rolling 24 hours, and the limit grows as you prove you send quality messages:
- New numbers start at 250 unique customers per 24 hours.
- As you send healthy volume, you climb automatically: 1,000, then 10,000, then 100,000, then unlimited.
- Completing Business Verification raises your starting tier.
Two things gate all of this:
- Quality rating. Meta grades every number Green, Yellow, or Red based on how people react to your messages: reads, replies, blocks, and reports. A drop to Yellow freezes your tier, and Red can cut your limit or pause the number entirely. See Meta's messaging limits documentation for the current thresholds.
- Portfolio-level limits. Since October 2025, these limits are shared across all the numbers in your Meta Business Portfolio, not counted per number.
The takeaway: limits are earned, not bought. Send relevant messages to people who opted in, and the ceiling rises on its own.
How much does a WhatsApp broadcast cost in 2026?
This is where most articles are out of date. Since July 1, 2025, WhatsApp charges per message, not per 24-hour conversation. You pay for each delivered template message, priced by category and the recipient's country. There are four categories (Meta's pricing docs have the full rate card):
- Marketing: promotions, launches, offers, abandoned-cart nudges. The category that drives revenue, and the one you are usually paying for.
- Utility: order, payment, and account updates triggered by something the customer did. Non-promotional.
- Authentication: one-time passwords and verification codes.
- Service: your free-form replies to a customer inside the conversation window.
A few money savers worth knowing:
- Service messages are free.
- Utility templates are free when sent inside the 24-hour customer-service window (after a customer messages you).
- Everything is free for 72 hours after a customer taps an ad that clicks to WhatsApp or a Page call-to-action button.
- Utility and authentication get cheaper at higher volume.
One trap: do not label a Marketing message as Utility to pay less. Meta's classifier detects promotional content, re-categorizes it, and dings your quality rating. If it sells something, send it as Marketing.
How do you send a WhatsApp broadcast? Step by step
1. Get on the WhatsApp Business Platform through a provider, and verify your business.
2. Collect opt-ins, and ask people to save your number. Add a checkbox at checkout, a website widget, a keyword to text, or an ad that clicks to WhatsApp, and keep a record of consent. For app-based broadcast lists, only contacts who have saved your number will receive the message, so prompt people to save it with a QR code that pre-fills your number or a thank-you page that explains how.
3. Build and segment your audience. Group contacts by behavior, lifecycle stage, location, or language instead of one giant list.
4. Create and submit a template in the right category, with variables for personalization (name, order, product link, coupon). Templates need Meta approval.
5. Personalize and preview. Insert per-recipient values and check how the message looks on a phone before you send.
6. Schedule or send, and pick the right moment for the audience and time zone.
7. Handle the replies. A broadcast is a conversation starter, so route responses to your team or an AI assistant with full context.
8. Measure and iterate. Track delivery, read, click, and reply rates, then refine your copy, timing, and segments.
How do you write a WhatsApp broadcast that gets read?
The message is where most broadcasts fail. Long paragraphs, two competing offers, and a generic opener all kill replies. A high-performing broadcast follows four parts, in order:
- A personalized opener with the recipient's name.
- One clear, specific offer or update.
- Social proof or urgency, but only where it is genuinely earned.
- A single call to action.
That is the whole structure. Messages that try to sell two things, or add a second button, consistently underperform. Do one thing, and make it easy to act on.
Your first line is your subject line. It shows in the notification preview before anyone taps to open, and people decide in seconds. Be specific: "Your 20% discount expires tonight" beats "We have an exclusive offer for you." Lead with the benefit, not your brand name, and only use urgency that is real.
WhatsApp broadcast template examples
Use these as starting points and adapt them to your brand voice:
- Promotional: "Hi {{name}}, get 20% off your next order at [Brand] with code SAVE20. Valid until Friday: [link]"
- Transactional (utility): "Hi {{name}}, your order #{{order_id}} is confirmed. Expected delivery: {{date}}. Reply if you need help."
- Re-engagement: "Hey {{name}}, it has been a while. We have added new features since you last checked in. Here is what is new: [link]"
Each one has a personalization token, a single specific update or offer, and one clear next step.
What are the best practices for WhatsApp broadcasts?
- Make opt-in non-negotiable. WhatsApp is not a cold-outreach channel. Use a clear opt-in, ideally double opt-in. No consent means blocks, and blocks kill your quality rating.
- Keep a consent record. For GDPR and CCPA, log who opted in, when, through which channel, the exact wording they agreed to, and their opt-out history. A clean consent ledger protects both your customers and your account.
- Segment, do not blast. A relevant message to 500 people beats a generic one to 50,000. Four cuts cover most cases: purchase history (buyer vs non-buyer, repeat vs first-time), engagement (active in the last 30 days vs dormant), location (for time zone and regional offers), and funnel stage (lead, trial, customer, at-risk). Send the abandoned-cart nudge only to people who abandoned a cart.
- Cap your frequency. Around two to four marketing messages per contact per month for active segments, and roughly one per 30 days for lapsed ones. Meta also enforces a per-user marketing cap that can silently block over-senders.
- Time it well. Mid-morning (9 to 11am) and early evening (6 to 8pm) local time tend to land best on mobile. Avoid Monday mornings and late nights, and even active lists rarely need more than two or three broadcasts a week. Then test against your own data, because the best send time is the one your list actually responds to.
- Always offer an exit. Put "reply STOP to unsubscribe" or an opt-out button on every marketing broadcast. It protects your rating and your reputation.
- Personalize for real. Use the recipient's name, last order, or a product link, not just a first-name token.
- Lead with value and a clear action. One message, one purpose, one button.
- Preview and test before every send.
How do you measure performance and protect deliverability?
Four metrics tell you almost everything:
- Delivery rate (delivered divided by sent): is your list clean, and have people saved your number?
- Read rate (read divided by delivered): are your content and timing relevant?
- Reply rate: is your call to action compelling enough to get action?
- Click-through rate: does your offer turn curiosity into intent?
As aspirational targets for a warm, well-segmented list, aim for delivery above 90 percent, read above 70 percent, and replies in the 15 to 30 percent range, then calibrate against your own baseline. Keep it honest: the measured open rate across all senders is closer to 60 to 68 percent, so treat 70 percent as a goal for your best segments, not a guarantee. A falling read rate is the earliest sign of list fatigue.
To protect deliverability over time:
- Prune inactive contacts every 60 to 90 days.
- Rotate message formats so people do not see the same template structure every time.
- Watch your template quality ratings in WhatsApp Business Manager, and pause any template that starts slipping before it drags down your account.
- Reply fast to inbound messages to keep the 24-hour service window open, where richer non-template replies are free.
What WhatsApp broadcast mistakes should you avoid?
- Using scraped or "unofficial" bulk senders. They violate Meta's policies and get numbers banned. Stick to the official Platform.
- Skipping opt-in, then wondering why deliverability collapsed.
- One unsegmented list that sends everyone everything.
- Over-messaging until people mute, block, or report you.
- Gaming the category by labeling marketing as utility.
- No opt-out on marketing sends.
- Ignoring the quality rating until the number is throttled or paused.
- Treating it as one-way. The whole advantage of WhatsApp is that people reply. If no one is ready to answer, you waste the channel.
How to send WhatsApp broadcasts with Invent
In Invent, every broadcast starts as either Marketing or Transactional, so the same composer covers campaign sends and event-triggered messages.
Invent runs broadcasts on the official WhatsApp Business Platform, so you get approved templates and proper opt-in compliance, not scraped routes that risk your number. It covers both marketing broadcasts (one message to a segment, sent now or scheduled) and transactional broadcasts (single event-triggered messages like order confirmations, receipts, or one-time passcodes, fired from your backend through the API). You also bring your own providers, so your sender reputation, IPs, and phone numbers stay yours. From one dashboard you can:
- Segment contacts in a built-in, CRM-style workspace using tags and properties like last purchase, plan, location, or language.
- Personalize every message with per-recipient variables (coupon code, product link, first name) and a live template preview before you send.
- Run multi-channel campaigns across WhatsApp, Email, and SMS from the same composer, then schedule or send instantly.
- See every broadcast inside the conversation. When a customer replies, your team and your AI assistant can see exactly which broadcast they received and how they engaged, so replies have full context.
- Let AI handle the first reply and the routine questions, then hand off to a human with the whole history attached.
- Measure delivery, read, click, and reply rates, and connect campaigns to the conversations and sales they create.
The difference between businesses that get strong broadcast ROI and those that do not is simple: the first group built a loop, the second built a send button. A practical loop looks like this:
1. Segment your contacts by tag (purchase history, engagement, or funnel stage).
2. Send an approved template to each segment with relevant, specific messaging.
3. Let a conversational AI flow handle what comes next: it answers replies, qualifies intent, and follows up automatically with anyone who goes quiet.
4. Route high-intent conversations to a human agent with full context.
The broadcast loop, end to end: segment, send a template, follow up, let AI reply, hand off to a human.
Invent runs that entire loop from one inbox, so the broadcast, the reply, the follow-up, and the handoff all live in the same place. For a wider look at the options, see our guide to the best WhatsApp Business automation tools and strategies.
Broadcast pricing is usage-based, and you only pay for messages delivered successfully: $0.004 per WhatsApp message and $0.001 per Email or SMS, deducted from your credit balance. Because you use your own providers, their delivery fees are billed separately. For a click-by-click walkthrough, see our step-by-step guide to WhatsApp Broadcasts with Invent.
Frequently asked questions
What is a WhatsApp broadcast?
A WhatsApp broadcast sends one message to many contacts at once, while each person receives it as a private one-to-one chat. They cannot see the other recipients, and they can reply directly to you. At business scale, broadcasts are sent through the WhatsApp Business Platform using approved template messages to customers who opted in.
How many people can I send a WhatsApp broadcast to?
In the free WhatsApp Business app, a broadcast list is capped at 256 contacts who have saved your number. On the WhatsApp Business Platform, you start at 250 unique customers per 24 hours and scale automatically to 1,000, then 10,000, then 100,000, then unlimited as your sending volume and quality rating grow.
How do I increase my WhatsApp broadcast limit?
Your limit rises automatically as you send quality messages to people who opted in. Complete Business Verification, keep your quality rating Green by avoiding blocks and reports, and send relevant, well-segmented campaigns. Limits climb from 250 to 1,000 to 10,000 to 100,000 to unlimited unique customers per 24 hours, and since October 2025 they are shared across all numbers in your Meta Business Portfolio.
How much does a WhatsApp broadcast cost in 2026?
Since July 1, 2025, WhatsApp charges per delivered template message, priced by category (marketing, utility, or authentication) and the recipient's country. Service replies are free, utility templates are free inside the 24-hour customer-service window, and all messages are free for 72 hours after a customer taps an ad that clicks to WhatsApp.
Is WhatsApp broadcast free?
The free WhatsApp Business app lets you broadcast to up to 256 saved contacts at no cost. On the WhatsApp Business Platform you pay per delivered template message by category and country, but service replies, utility templates inside the 24-hour window, and all messages for 72 hours after an ad-click-to-WhatsApp are free. With a platform like Invent, broadcasts are usage-based, so you pay only for the messages you actually deliver.
Do I need opt-in to send WhatsApp broadcasts?
Yes. Customers must opt in before you message them, and every marketing broadcast must include an easy way to opt out. WhatsApp is not a cold-outreach channel, and sending without consent triggers blocks and reports that damage your quality rating.
WhatsApp broadcast vs email: which is better?
WhatsApp wins on engagement, with measured open rates around 60 to 68 percent and click rates of 15 to 25 percent, versus roughly 20 to 25 percent open and 2 to 3 percent click for email. Email still wins for long-form content and very large, low-cost sends. Most teams use both: WhatsApp for high-intent, time-sensitive messages, email for richer storytelling.
What is the best tool to send WhatsApp broadcasts?
Look for an official WhatsApp Business Platform partner with easy opt-in management, segmentation, personalization, two-way reply handling, and analytics. Invent covers all of this, adds Email and SMS in the same campaign, and shows every broadcast inside the customer conversation so replies keep their context.
Ready to turn broadcasts into conversations?
WhatsApp broadcasts are the rare channel that scales and stays personal. Get the opt-in, the segments, and the replies right, and it becomes the channel your customers actually look forward to.
