The Broadcast Engine is designed for high-volume message delivery. Whether sending a weekly newsletter or a flash sale notification, the engine provides the tools to manage large-scale distribution with confidence.

​
Campaign Creation

Building a broadcast follows a streamlined workflow to ensure accuracy and compliance.

​
1. Audience Selection

Select recipients from your contact database using:
  • Tags: Target specific segments like vip-customers or beta-testers.
  • Imported Lists: Use contacts from a recent CSV import.
  • Filters: Combine criteria (e.g., “Tag = ‘Newsletter’ AND Region = ‘UK’“).

​
2. Audience Preview

Before sending, the Audience Preview tool shows you a sample of the recipients. This helps verify that your variable mappings (like {{name}}) are pulling data correctly from the contact records.

​
3. Template Configuration

Select an approved template and map variables to contact fields. The preview will update dynamically to show how the message looks for the selected audience sample.

​
Scheduling and Sending

The Broadcast Engine supports both immediate and planned delivery.

​
Schedule Picker

  • Send Now: Immediate dispatch to the fan-out engine.
  • Scheduled Send: Select a specific date and time in the future.
  • Timezone Awareness: Choose whether to send at a fixed UTC time or at the recipient’s local time (requires contact timezone data).

​
Fan-out Engine

Our proprietary fan-out engine manages delivery at scale:
  • Rate Limiting: Automatically adheres to your WABA’s current messaging tier limits.
  • Queue Management: Prioritizes messages to ensure timely delivery even during peak traffic.
  • Throughput Monitoring: Real-time tracking of send success rates.

​
Analytics and Reporting

Once a broadcast is live, monitor performance in the dashboard:
  • Delivery Rate: Percentage of messages successfully accepted by WhatsApp.
  • Read Rate: Percentage of delivered messages opened.
  • Click-through Rate: Engagement with buttons or links.
  • Conversion Tracking: Success against predefined campaign goals.
  • Meta Usage & Cost: Settings → Usage estimates delivered-template Meta costs, free service-window traffic, and per-campaign spend attribution across 7-day, 30-day, and month-to-date windows.
See Meta Usage & Cost Monitor for the estimate model and caveats.

​
Safety Measures

  • Deduplication: Automatically prevents sending the same broadcast to a contact multiple times within a 12-hour window.
  • Opt-out Handling: Automatically excludes contacts who have used the “Opt-out” button on previous marketing messages.
  • Safety Preflight (opt-in): A workspace can require a passing campaign_safety_audits preflight before a campaign is allowed to launch — a hard-block severity ladder gates launch, and a recipient-set hash check refuses a launch if recipients changed since the audit ran. See Campaign Safety Preflight for the full gate model and data shape.
