How to Send Bulk WhatsApp Messages Legally in India

Opt-in rules, approved templates, and WhatsApp Business Policy basics for Indian businesses using Cloud API broadcasts.

Direct answer

Legal bulk WhatsApp in India means messaging people who opted in to hear from your business, using Meta-approved message templates through the WhatsApp Business Platform, and respecting WhatsApp Business Messaging Policy plus applicable Indian laws (including TRAI DND considerations for promotional content).

WhatsInfinity helps you organize opted-in contacts, send template broadcasts, and log delivery outcomes — but compliance remains your responsibility as the business sender.

Checklist before you broadcast

  • Collect explicit opt-in (website form, checkout, in-store consent, or lead ad with clear WhatsApp follow-up disclosure)
  • Use only approved WhatsApp templates for outbound marketing outside the 24-hour session window
  • Include an opt-out path where required and honour unsubscribe requests promptly
  • Avoid purchased or scraped contact lists
  • Keep records of consent and campaign logs for audits

How WhatsInfinity supports compliant outreach

Templates are synced from Meta — you cannot send arbitrary marketing text outside policy. Broadcasts target your customer list inside WhatsInfinity with per-recipient status (sent, delivered, read, failed). Failed sends often indicate invalid numbers, template issues, or policy blocks — fix the root cause instead of retrying blindly.

Frequently asked questions

Is cold messaging allowed on WhatsApp?
No. WhatsApp prohibits unsolicited messages. Only contact users who expect messages from you.
Can WhatsInfinity send messages without templates?
Session messages are possible within Meta rules when a user has recently messaged you. Marketing outside that window requires approved templates.
