Reach thousands without burning your numbers
Send to lists on WhatsApp with human-like pacing, rotation across numbers, gradual warm-up and an automatic pause at the first sign of a block. Opt-out and consent built in.
Campaigns with a safety autopilot
Reach thousands with an anti-ban expert built in. You bring the list and the template; bZapper handles the pacing, the warm-up and the protection of your numbers — on its own.
Build the template
Use variables like {name} and {amount}, plus up to 3 variations that bZapper rotates to escape the identical-message pattern.
Upload the list
Each contact with its own content. Anyone who replied “STOP” is blocked automatically.
Start and relax
The autopilot drips the sends at a safe pace, spreads them across numbers and shows everything on a live dashboard.
What the autopilot does for you
- Human pace
Randomized intervals, per-number caps and a time window — no burst that fries a chip.
- Number rotation
Spreads volume across your numbers (2+ required). Concentrating it on one is what gets you blocked.
- Automatic warm-up
A new number enters a gradual ramp; it only gains volume once it matures.
- Smart pause
If it senses a block signal, it pauses the campaign on its own and warns you — before the ban.
3 rotated variations · {name} and {amount} filled per contact
Campaigns require the Pro plan and, by default, 2 warmed numbers (7+ days) — bZapper rotates across them and protects your chips. The minimum is adjustable per account.
WhatsApp over an API, without interruption
Delivery is engineering. Every number in the project has its own volume limits, send pacing, continuous health monitoring and real-time alerts. When a number goes down, traffic keeps flowing through the others — with no action from you.
- Load spread across the numbers in the project
- Gradual volume ramp-up on newly connected numbers
- Conversations unified per contact, even when switching numbers
- Real-time alerts when a number goes down
