Anti-Ban Pacing & Limits
Bulk sending is the fastest way to get a WhatsApp number banned — so Loopwave makes the safe path the only path. A broadcast is delivered by a background worker that sends one recipient at a time, with deliberate randomized delays and a hard daily ceiling. You can’t accidentally fire a burst.
The four safeguards
The worker never sends in bulk. Each tick handles a single recipient, then waits.
Between sends, Loopwave waits a random 8 to 20 seconds, so the cadence looks human, not scripted.
Sending stops once the daily ceiling is reached and resumes the next day, so a single number never blasts thousands in 24 hours.
If the sending number isn’t connected and ready, the broadcast pauses instead of failing every remaining recipient.
What this means in practice
- A 100-recipient broadcast takes roughly 20–30 minutes to send, by design — not seconds.
- A campaign larger than the daily cap automatically spreads across multiple days.
- If a number drops mid-send, the campaign waits and picks up where it left off once the number reconnects.
- Cancelling stops the worker on its next tick; remaining recipients stay unsent.
These limits are intentionally conservative defaults baked into the worker. They exist to protect your number — the most valuable asset in your account.
Your responsibility
Pacing protects you from how you send, but not from who you send to. The safeguards can’t fix a bad list. To stay safe, also:
- Only broadcast to opted-in recipients.
- Personalize with
{{name}}and vary your copy. - Offer an opt-out (“reply STOP”) and honor it immediately.
- Warm up new numbers before broadcasting — see Warming up new numbers.
Everything that keeps a number healthy at scale.
