Features

Everything you need to
ship messaging fast

From a single-message API call to a 1,000-recipient bulk campaign — WA Blast handles it all with zero configuration.

⚡

REST API in seconds

One POST request. Authenticate with your sk_ key, send a message. No SDKs required — curl works.

📤

Bulk messaging

Upload CSV or pass JSON. Per-contact variable substitution and spintax randomisation to avoid filters.

📋

Template library

Reusable templates with {variable} slots, {spin|variations}, and multi-media support.

📱

Multiple accounts

Connect unlimited WhatsApp numbers. Smart idle-disconnect preserves sessions and saves memory.

📊

Delivery tracking

Every message: queued → sending → sent → delivered. One-click retry for failed messages.

🛡️

Anti-ban by design

Randomised delays, stable browser fingerprint, no presence broadcasts. Your accounts stay safe.

⚙️

Auto-failover

Multi-process worker fleet. Dead-worker stale locks are stolen in seconds. Zero message loss.

💰

Fair usage quota

Flat monthly plans. Burst protection at queue time prevents over-sending before limits.

Analytics

Full visibility into every message

Track delivery, retry failures, monitor bulk jobs — all in one place.
