WhatsApp blast FAQ

What is WhatsApp blast?

Bulk WhatsApp to a contact list. LoginWA: dashboard CSV and schedule, or POST /api/v1/messages/send in a loop. 1 blast = 1 quota unit.

How is WhatsApp blast different from WhatsApp’s built-in broadcast?

WhatsApp’s built-in broadcast is limited to contacts who have saved your number and must be done manually. With the LoginWA broadcast WhatsApp API, you can send to a contact list from your system/CRM, schedule delivery, personalize messages, and track delivery status.

How do I keep WhatsApp blast from getting blocked easily?

LoginWA uses smart number rotation, send throttling, and failover to lower the blocking risk. We still recommend sending to relevant contacts, using non-spammy messages, and providing an unsubscribe option.

Can WhatsApp blast be scheduled and personalized?

Yes. You can schedule delivery and personalize message content (for example customer name, invoice number) through the broadcast WhatsApp API.

How much does WhatsApp blast cost?

Cost follows your subscription plan based on the monthly message quota. Pricing is in USD from $1/month; start free with 100 messages, then upgrade via instant QRIS for the blast volume you require.
