How to Run a WhatsApp Broadcast Campaign That Actually Works
Sending a bulk WhatsApp message is easy — sending one that gets responses and drives sales takes a bit more thought. Here is a practical guide.
What is a WhatsApp Broadcast?
A WhatsApp broadcast is a message sent to multiple contacts simultaneously via the WhatsApp Business API. Unlike a group message, each recipient receives it as an individual conversation — it feels personal, not mass.
Before You Send: Know Your Costs
WhatsApp charges per conversation, not per message. A broadcast to 1,000 contacts opens 1,000 marketing conversations — each billed at the marketing rate for your country.
Use the free Broadcast Cost Estimator to calculate your total cost before you send. And the WhatsApp ROI Calculator to estimate whether the campaign is worth it.
Message Quality Matters
Meta monitors the quality of your templates and conversations. Low open rates and high block rates will downgrade your phone number quality rating, limiting future sending.
Do:
- Send to opted-in contacts only.
- Time your message when recipients are likely to be free.
- Include a clear call to action — reply, click, or visit.
Do not:
- Blast promotions to unqualified lists.
- Use misleading subject lines in your template header.
- Send the same template repeatedly without variation.
Use a Proper Platform
The WhatsApp Business App caps broadcasts at 256 contacts and lacks analytics. For scale, use the WhatsApp Business API through a provider like Tenreply — which adds template management, contact segmentation, delivery reports, and two-way inbox management.
Preview Before You Submit
Always use the Template Message Previewer to check your message renders correctly before submitting to Meta for approval.
