WhatsApp broadcasts can reach opted-in customers through approved templates. The free WhatsApp Business mobile app caps broadcast lists at 256 contacts, while the WhatsApp Business API supports larger, governed campaigns with templates and delivery controls. Here is how to run one without putting your number at risk.

The Two WhatsApp Broadcast Paths

Path 1: WhatsApp Business mobile app (free, capped)

What you get: Broadcast lists up to 256 labeled contacts. Each recipient sees the message individually (private from each other).
Limits: 256-contact cap per list, no automation, no template management, no opt-in tracking, no analytics, no team inbox.
Fits: Solo operators sending a few hundred messages a month, where 256 contacts is enough.

Path 2: WhatsApp Business API (paid, unlimited scale)

What you get: Broadcasts to thousands or hundreds of thousands, template management, opt-in tracking, delivery analytics, multi-user inbox, AI replies on inbound responses.
Cost: Meta message rates vary by category and market. Software runs $59-300/mo depending on provider. Instant Reply Growth is $129/mo ($107.50 annual) with broadcasts plus the AI closer included.
Fits: Any business sending more than 256 broadcast messages or running automation alongside broadcasts.

What It Costs to Send a Real WhatsApp Broadcast

Two cost layers: Meta's message pricing, plus your software subscription.

Meta's message pricing (rough 2026 numbers)

Marketing templates: paid per delivered message; rates vary by market and category
Marketing conversation in India: ~$0.0086
Marketing conversation in Brazil: ~$0.064
Utility conversation in the US: ~$0.015
Authentication conversation: $0.0135-$0.0768 depending on country

So a 1,000-contact US marketing broadcast: ~$80 in Meta fees. A 5,000-contact US marketing broadcast: ~$400 in Meta fees. A 5,000-contact Indian marketing broadcast: ~$43.

Software subscription (the part you control)

WATI Pro: ~$99/mo for 5 users, then $24/extra user. AI Co-pilot metered separately.
Respond.io Growth: $159/mo for 10 users with AI included, but MAC overage can add $100-400/mo.
Gallabox Scale: $197/mo for 6 users (3 on Growth at $89/mo).
Instant Reply Growth: $129/mo ($107.50 annual) flat. Broadcasts + AI closer + voice transcription + image understanding included. No per-user fees on the entry tiers, no MAC overage, no AI credit packs.

The Compliance Rules That Keep Your Number Alive

Meta is strict about WhatsApp broadcast compliance. Cross the line and your number gets suspended; in extreme cases, your entire Meta Business Account gets restricted.

Rule 1: Explicit opt-in for marketing templates

Every contact you broadcast a marketing template to must have given explicit opt-in. Store the opt-in source and timestamp for every contact. Common compliant opt-in points:

Website signup form with a checkbox: "Yes, I'd like to receive WhatsApp updates from [brand]."
Click-to-WhatsApp ad: the click counts as opt-in if the ad copy makes it clear.
In-person sign-up at point of sale with a clear opt-in line on the receipt or form.
Existing customer post-purchase opt-in via the order confirmation.

What doesn't count: purchased lists, scraped numbers, "implied" opt-in from any other channel.

Rule 2: Honor opt-outs immediately

Every broadcast must include a clear opt-out path: "Reply STOP to unsubscribe" or a button. Process opt-outs in real time. A user who replies STOP and gets another marketing message in 24 hours reports your number, drops your quality rating, and triggers a suspension review.

Rule 3: Use only approved templates outside the 24-hour window

Inside the 24-hour customer-care window (after a customer messages you), you can send any free-form content. Outside it, you can only send Meta-approved templates. Trying to send free-form content outside the window fails silently or triggers a compliance flag.

Rule 4: Keep your quality rating green

Meta scores every business number on quality (Green / Yellow / Red). Drops happen when users block, report spam, or your delivery rate tanks. Green keeps you at higher messaging tiers; Red restricts your sending limits and can lead to suspension. Quality is the single most important metric to monitor.

Rule 5: Match template content to category

Submitting promotional copy as a utility template to obtain a different category can lead to rejection or policy problems. Marketing is promotional content. Utility is transactional, such as an order, appointment, or billing update. Authentication covers verification messages. Describe the real purpose of the message and let Meta make the final category decision.

Template Approval: What Gets Approved, What Gets Rejected

Templates that get approved fast

Order confirmations, shipping updates, delivery alerts (utility)
Appointment reminders and confirmations (utility)
Promotional offers with clear product/price (marketing, opt-in required)
Account-related authentication codes (authentication)
Customer survey or review requests (utility/marketing depending on framing)

Templates that get rejected

Misleading claims ("Guaranteed 10x ROI in 30 days")
Prohibited content (gambling in some markets, alcohol in others, adult content)
Free-form sales pitches that look like cold outreach
Templates with broken variables or unclear button actions
Marketing content submitted as utility (and vice versa)

Pro tip: write the template, get it Meta-approved, then variabilize the dynamic parts ({name}, {order_id}, {discount}). Don't submit ten variations of the same template; submit one well-built template with variables.

What to Send in a WhatsApp Broadcast (Templates That Convert)

Abandoned cart recovery (highest-ROI use case)

"Hey {first_name}, you left {product_name} in your cart. We're holding it for 24 hours. Want to grab it? [Complete order button]"

Recovery rate: 25-35 percent (vs ~10 percent for email abandoned cart). Send 1 hour after abandonment.

Flash promotion / new product drop

"{first_name}, our new {collection_name} just dropped. First 100 buyers get {discount}% off. Tap to shop: [link button]"

Best practice: short, urgent, single CTA, clear discount or scarcity.

Appointment reminder (utility)

"Reminder: your {service} is scheduled for {date} at {time}. Reply C to confirm, R to reschedule, X to cancel."

Cuts no-show rate by 30-50 percent vs email reminders alone.

Review request

"{first_name}, thanks for choosing us. Quick favor: would you take 30 seconds to rate us? [5-star button][1-star button]"

Pair with conditional logic: 5 stars → public review link. 1-4 stars → internal feedback form. Automate this with Instant Reply.

Order shipped (utility, transactional)

"Your order #{order_id} just shipped. Tracking: {tracking_link}. ETA: {delivery_date}."

Highest deliverability category. Use as the foundation broadcast template for any commerce business.

Handling the Replies (This Is Where Most Tools Fail)

A WhatsApp broadcast to 5,000 people generates inbound replies. Typical reply rates run 5-15 percent, so a 5,000-contact broadcast generates 250-750 replies. Most BSPs hand off the replies to your team and walk away. That's where the AI closer matters.

Instant Reply's WhatsApp AI handles the inbound reply storm: transcribes voice notes, reads attached photos, frames replies with closer logic, and escalates only the conversations that need a human. The same plan that runs the broadcast handles the replies. AI auto-replies close the routine 70-80 percent of inbound, leaving your team focused on the 20-30 percent that needs judgment.

Send Your First Compliant Broadcast

WhatsApp broadcasts done right are the highest-converting channel available to a small business in 2026. Done wrong, they get your number suspended in 72 hours. The difference is opt-in discipline, template hygiene, and a tool that enforces compliance automatically.

Instant Reply ships the WhatsApp Business API access, template submission, opt-in tracking, broadcast scheduling, and the AI closer that handles inbound replies, all on one plan.

FAQ

Frequently asked questions

Quick answers to what people ask most.

Only the WhatsApp Business API can broadcast to 5,000+ recipients. The free WhatsApp Business mobile app caps broadcast lists at 256 labeled contacts. With API access through a Meta-approved BSP like Instant Reply, you submit a marketing or utility template (approval timing varies because Meta makes the final decision), upload an opt-in contact list, and run the broadcast. Meta charges eligible template messages by category and market. Marketing templates require explicit opt-in from every recipient.
A broadcast list sends the same message to many recipients individually; each recipient sees only your message and replies only to you (private). A group chat shows every member's identity to every other member; replies go to the whole group (public). Broadcasts are for marketing and announcements; groups are for community. For business marketing, always use broadcasts, never groups.
Meta charges eligible outbound template messages by market and category. A 1,000-contact campaign's Meta cost depends on how many messages are delivered, the template category, and the recipients' markets. Add your software provider's fee separately; use Meta's current rate card and your provider's pricing for an estimate.
No. Meta requires explicit opt-in for every marketing-template recipient. Sending without opt-in triggers user reports, drops your quality rating, and gets your business number suspended. Utility templates (order updates, appointment reminders) are looser because they're transactional, but the safe rule is: collect opt-in for everyone, and offer a clear opt-out path in every broadcast.
You submit a template (text, images, video, buttons, variables) to Meta for review. Meta classifies it as marketing, utility, or authentication and approves or rejects based on content policy. Approval timing varies because Meta makes the final decision. Rejections may include a reason; common risks include misleading claims, prohibited content, or template structure errors. Approved templates can be reused until their status or content changes.
Six rules: 1) Use the official WhatsApp Business API, not the consumer app for bulk messaging. 2) Get explicit opt-in for every marketing recipient. 3) Send only Meta-approved templates outside the 24-hour customer-care window. 4) Honor opt-outs immediately. 5) Don't blast purchased or scraped lists. 6) Keep your quality rating green by avoiding spammy content. Compliant tools like Instant Reply enforce these automatically.
When a customer messages you, you have 24 hours to reply with any free-form content (text, media, voice). After 24 hours of customer silence, you can only send pre-approved templates. The 24-hour window resets every time the customer sends a new message. For broadcasts initiated by your business outside an active conversation, the template rule always applies.
For high-volume broadcasts with template management, opt-in tracking, and analytics, the best fit depends on your team. WATI is broadcast-focused and India-popular but caps users and meters AI separately. Respond.io supports broadcasts in a multi-channel inbox at higher price points. Instant Reply ships broadcasts plus an AI closer that handles the replies, voice transcription, and image understanding on the same plan, starting at $129/mo on Growth ($107.50 annual).
