Send bulk WhatsApp messages without risking your number
Upload a CSV, pick a Meta-approved template, and send — with automatic rate limiting that keeps you inside Meta's safe thresholds, campaign after campaign.
Start Free TrialHow does compliant bulk WhatsApp messaging work?
Bulk WhatsApp messaging is legal and safe in India when done through the official WhatsApp Business API, sent only to contacts who have explicitly opted in, using Meta-approved message templates for the outreach.
The risk isn't the volume — it's how the volume is sent. Sending too fast, to un-opted-in numbers, or through unofficial tools is what triggers WABA quality drops and bans. A proper bulk sender rate-limits sends to stay under Meta's per-number and per-WABA thresholds automatically.
wChatFlowAI runs bulk sends on a dedicated queue with a two-bucket rate limiter — separate for platform-managed and self-hosted (BYO) WABAs — so one client's bulk job never affects another's sending capacity.

Frequently asked questions
Is bulk WhatsApp messaging legal in India?
Yes, when sent through the official WhatsApp Business API to contacts who have explicitly opted in, using Meta-approved templates. Unofficial bulk-sending tools and unsolicited messaging violate Meta's policy and India's DPDP Act, and risk a permanent WABA ban.
How does wChatFlowAI prevent my number from being banned during bulk sends?
A built-in two-bucket rate limiter throttles outbound volume to stay within Meta's safe per-number and per-WABA thresholds, and continuously monitors your quality rating, slowing sends automatically if it starts to drop.
What happens if a bulk job is interrupted halfway through?
Recovery tasks run automatically every few minutes to retry failed dispatches, re-queue stuck messages, and resume held jobs — a bulk campaign doesn't need to be manually restarted after a worker restart or a temporary Meta rate-limit response.
Does the system prevent duplicate messages if the same number appears twice in my CSV?
Yes. Duplicate phone numbers are detected at import time and silently skipped, so a contact is never messaged — or billed — twice from the same list.
