WhatsApp Broadcast: What It Is and How to Send One

01 · Glossary

Broadcast vs. campaign

The words are used interchangeably, but the mechanics differ.

• Broadcast: the raw act of sending one message to many recipients
• Campaign: the managed version — segment, template, schedule, follow-up
• On the API both use approved templates and bill per conversation
• Managed campaigns add tracking, targeting, and opt-out handling

The rules that keep you unbanned

Broadcast failures are rarely technical; they are compliance failures.

• Every recipient must have opt-in with a timestamp
• Purchased or scraped lists are the fastest route to a ban
• Honor STOP replies instantly during and after the send
• Match volume to your number's quality rating
• Start slow on new numbers and grow gradually

What a broadcast costs

Each recipient is a conversation, so the bill scales with the list.

• Marketing template: $0.025 per conversation in the US
• Utility broadcast: $0.004 per conversation in the US
• Rates follow the destination country tier
• Wutt adds zero markup — the calculator shows the list cost before you send

How Wutt runs broadcasts

Wutt blocks sends to contacts without opt-in, auto-handles opt-out keywords, and surfaces quality signals before launch. The broadcast checker reviews a list for the patterns that get numbers banned — before the send, not after.

• Sends blocked without opt-in
• Opt-out keywords auto-handled
• Broadcast checker reviews the list before launch
