How to Send Bulk WhatsApp Messages Without Getting Banned
Unofficial bulk senders get numbers banned fast. Here's the safe, official way to reach thousands of customers on WhatsApp.
Why numbers get banned
Most bans come from 'grey-route' bulk sender tools that automate the personal or Business app against WhatsApp's terms. Meta detects the pattern — high volume, no opt-in, spam reports — and blocks the number, often permanently.
Rule 1: Use the official WhatsApp Business API
The official Cloud API is the only sanctioned way to message at scale. Sandeshly is built entirely on it — your own number and WhatsApp Business Account, no grey routes, no ban risk from the tooling itself.
Rule 2: Only message opted-in contacts
Get explicit opt-in before you message someone. Quality ratings drop when people block or report you, and a low quality rating throttles your sending. Clean, consenting lists are the foundation.
Rule 3: Use approved templates and respect the session window
Business-initiated messages must use Meta-approved templates. Free-form replies are only allowed inside the 24-hour customer service window. Sandeshly handles template approval and the session window for you.
Rule 4: Warm up and pace your sending
Don't blast your full list on day one from a fresh number. Sandeshly throttles sends to stay within Meta's tier limits and ramps volume as your number's messaging tier increases.
