The basics
Understanding bulk WhatsApp broadcast
A bulk WhatsApp broadcast sends one approved message to a large contact list in a single campaign, using WhatsApp Cloud API integration instead of forwarding messages one by one from a phone. TeamInbox operates as a WhatsApp Business Solution Provider (BSP), so every broadcast runs through Meta's own infrastructure, with Green Tick verification (Official Business Account) available for numbers that qualify, and template message pre-approval required before any promotional message goes out.
Every broadcast is filtered through explicit opt-in consent protocols, so contacts must agree to receive messages before a template can reach them. Meta tracks each number against a phone number quality rating of Green, Yellow, or Red status, and that rating decides which messaging limit tier, from Tier 1 up to unlimited daily limits, your account can send within. Understanding Meta conversation-based versus per-message billing rates, and following account block and spam report prevention practices, keeps a broadcast number healthy long after the first campaign ships.
Use same WhatsApp number on app and API simultaneously
The number, the profile, and the verified status stay the same. Only where you send and receive messages from expands to include your API-connected tools like TeamInbox, so nothing about your existing setup gets replaced.
Keep WhatsApp Business app while using API
Existing conversations on the app remain intact, and going forward, messages sent or received through the API are synced back to the app through a linked companion device, so history stays in one place.
Campaign Flow
How a bulk WhatsApp broadcast goes out
Four steps, from list to inbox to dashboard, run on the same official broadcast infrastructure every time.
-
Build and segment your list
Import contacts and apply broadcast list segmentation by tag, purchase history, or opt-in date, so every campaign reaches the right group instead of your entire list.
-
Get the template approved
Submit your message using interactive message templates, including Quick Reply and CTA buttons, for Meta's approval before it can be used in a broadcast.
-
Personalize and schedule
Add dynamic personalization variables like name, order number, or city, then schedule the send for the moment your audience is most likely to open it.
-
Send, track, and manage opt-outs
Watch open rates, click-through rates (CTR), and conversion tracking roll in live, while opt-out management through STOP keyword triggering keeps your list compliant automatically.
Built Around Compliance
What keeps a broadcast
What keeps a broadcast
number healthy
Scale is only useful if the number sending the messages stays trusted by Meta and welcomed by contacts.
Free replies inside the service window
When a customer responds to a broadcast, TeamInbox opens the 24-hour customer service window automatically — so your team can reply freely without needing another approved template.
Delivery, read, and click tracking
Every broadcast reports delivery, read, and click status per contact, so an underperforming template can be paused and rewritten before a full list burns through.
Multi-agent send approval
Route campaigns through an approval step before they leave, so a broadcast never ships to a live list without a second set of eyes on the copy and the audience.
Segment-level throttling
Large lists send in controlled batches rather than all at once, protecting your quality rating while still finishing a full campaign within the day.
Template library with version history
Keep every approved, rejected, and draft template in one library — so nothing waits on Meta's review twice for a wording change that already cleared once.
Consent records kept per contact
Every opt-in and opt-out is timestamped and stored against the contact, giving you a clear record if Meta or a customer ever asks how consent was collected.
App Broadcast Versus API Broadcast

Both can reach a list. Only one is built to reach a large one safely, with rate limits, tracking, and consent handled for you.

Frequently Asked Questions
Bulk WhatsApp broadcast, common questions
A bulk WhatsApp broadcast sends one approved template message to a large, opted-in contact list in a single campaign through the WhatsApp Business API, rather than forwarding messages one by one from a phone.
Business App broadcasts are capped near 256 contacts, sent manually, and offer no tracking or quality rating visibility. API broadcasts run through TeamInbox with list segmentation, pre-approved templates, live analytics, and automatic opt-out handling at any scale.
Daily limits depend on your phone number's quality rating and messaging tier, ranging from around 1,000 contacts per day at Tier 1 up to unlimited daily sends for numbers with a strong, consistent quality rating.
It is a message format, including any variables, buttons, or media, that Meta has reviewed and approved in advance. Only approved templates can be used to start a conversation in a bulk broadcast.
Keep every recipient opted in, use approved templates only, segment lists instead of blasting your entire base at once, honor STOP requests immediately, and let your quality rating rise gradually before increasing send volume.
Meta requires clear, documented consent before a business can message someone, collected outside of WhatsApp itself, such as through a website form, checkout flow, or in-store sign-up, with the business identified by name at the point of opt-in.
A Green rating unlocks higher and eventually unlimited daily sending tiers. A Yellow rating signals rising blocks or reports and caps growth. A Red rating restricts messaging until the number's rating recovers.
Cost is driven by Meta's conversation-based pricing per recipient country, plus TeamInbox's plan fee for list management, template governance, and analytics. Starter, Growth, and Enterprise plans price this differently based on volume.
Each sent template is billed as a Meta conversation, priced by destination country and conversation category, on top of TeamInbox's platform fee. Session replies inside the 24-hour service window are typically free of Meta's per-conversation charge.
Look for a tool built on the official WhatsApp Business API with list segmentation, template approval tracking, scheduled sends, and analytics in one place. TeamInbox covers all of this alongside a shared inbox for the replies that follow.
