Frequently Asked Questions

How many contacts can I message at once?
Audience size and delivery throughput depend on your WACM plan, available credits, eligible opted-in contacts and Meta messaging limits. Preview the eligible audience before creating a campaign.
Do I need pre-approved templates for bulk messaging?
Yes. WhatsApp requires pre-approved templates for outbound bulk messages. You can create and submit templates through the WACM dashboard, and they're typically approved within 24 hours.
Can I personalize bulk messages?
Absolutely. Use dynamic variables like contact name, phone, custom fields, and runtime values (e.g., order ID) to personalize each message even in bulk campaigns.
What happens if some messages fail to deliver?
Failed messages are tracked in campaign analytics. Retry queues eligible failures and returns retried/skipped counts; protected messages are left unchanged. Review delivery and billing status when troubleshooting.
Can bulk messages trigger as bot replies?
Yes. You can set campaigns as bot replies by enabling is_bot=true and defining trigger keywords. When a contact messages with a matching keyword, the campaign template is sent automatically.
How do I track campaign performance?
Real-time tracking shows sent, delivered, read, and failed counts. Advanced analytics include Google Maps visualization of delivery locations and conversation traffic reports.
