WhatsApp Broadcast:
Start Real Conversations.
Nexvox WhatsApp Broadcast lets you send one message to thousands of contacts at once - and each recipient receives it as a private, personal chat. No group threads. No shared names. Just direct, one-to-one conversations at scale, backed by the WhatsApp Business API.
How WhatsApp Broadcast Works
Build Your Broadcast List
Import contacts from a CSV file, sync directly from your CRM, or segment existing customers by tag, purchase history, or engagement level. Lists update automatically as new contacts opt in.
Personalize at Scale
Insert first names, order details, appointment times, or any custom field into your approved message template - so every recipient gets content that feels written for them, even across a mass send.
Send and Track in Real Time
Launch the broadcast and monitor delivery rates, read receipts, and reply rates from the Nexvox dashboard. Failed sends and opt-outs are flagged automatically so your list stays clean.
Automate the Follow-Up
Replies flow straight into your unified inbox. Bots handle common questions instantly, and a single click escalates any conversation to a human agent the moment a personal touch is needed.
Email gets read once in 5.
WhatsApp gets read.
WhatsApp open rates regularly exceed 90% compared to roughly 20% for email - because WhatsApp is the app people check first.
- Open rates regularly exceed 90%, compared to roughly 20% for email
- Messages land in an app people already check dozens of times a day
- Rich media support - images, PDFs, videos, and clickable buttons
- Two-way replies turn a broadcast into a real conversation, not a one-way announcement
- Official WhatsApp Business API compliance keeps your number verified and spam-free
Everything You Need to Run Winning Broadcast Campaigns
Contact List Management
Import via CSV, sync from your CRM, or let contacts self-enroll through opt-in flows. Lists update automatically and keep themselves clean as opt-outs come in.
Message Personalization
Dynamic variables let you insert names, order numbers, appointment times, or any custom field - every recipient reads a message that feels handcrafted for them.
Real-Time Delivery Tracking
Monitor delivery, read receipts, click-throughs, and reply rates from a single dashboard as your campaign goes live. No waiting for batch reports.
Automated Reply Handling
Route all inbound replies into your unified inbox where pre-built bots can answer common questions immediately, reducing your team's manual workload.
Bot-to-Human Handoff
The moment a reply needs a personal touch, one click escalates the conversation to the right agent - with full context already visible, no re-explaining required.
WhatsApp API Compliance
Built-in template approval workflow, explicit opt-in management, and automatic opt-out handling keep your number verified and your campaigns within WhatsApp's Business Policy.

Five Rules for High-Performance Broadcasts
Always collect explicit opt-in consent
Add contacts only after they have actively agreed to receive WhatsApp messages from you. This keeps your list quality high and protects your Business API standing.
Keep messages short and well-timed
Send when your audience is likely to be active - mid-morning or early evening typically outperforms late-night sends. Brevity drives higher reply rates.
Use approved templates for first outreach
WhatsApp Business API requires pre-approved message templates for contacts outside the 24-hour reply window. Submit templates in advance to avoid delays.
Segment lists by interest or behavior
A promotion for loyal customers should never go to first-time visitors. Targeted broadcasts get higher engagement and fewer opt-outs than one-size-fits-all campaigns.
Monitor opt-out rates and adjust frequency
A healthy broadcast list has an opt-out rate well below 2%. If unsubscribes start climbing, reduce frequency before increasing it again, not the other way around.
