Collect opted-in numbers and send them things they asked for, from the free WhatsApp Business app at first and the WhatsApp Business Platform (API) once you need broadcasts at scale. Start in the app: a full business profile, a catalog, quick replies and a wa.me link on Instagram, your site and packaging. When the list outgrows one phone, move to the API through a provider: AiSensy has a Free Forever plan and broadcasts from ₹1,500 a month, Interakt's Growth plan is ₹2,799 a month, WATI's is ₹2,699 a month billed quarterly. Meta charges per delivered message by category (marketing, utility, authentication), from 1 October 2026 only the first 1,000 service messages a month per number are free, and messages to people who arrive from a click-to-WhatsApp ad are free for up to 7 days. Bulk-sending from a normal WhatsApp number breaks WhatsApp's terms. The rule: earn the opt-in, then use WhatsApp for order updates, restocks and drops rather than daily offers.
WhatsApp's consumer terms, which prohibit bulk messaging and auto-messaging from regular accounts; which is why 'bulk sender' tools that automate a normal number break WhatsApp's rules.
Lays out WhatsApp as a full commerce channel, catalogue, payments, cart recovery, post-purchase, not just a broadcast tool, with the sequencing (start with cart/order-update automation, build up to full conversational commerce) that matches how Indian founders actually roll it out.
WhatsApp's free app for small businesses: a business profile, catalog, greeting and away messages and quick replies on one phone number, the right first step before paying for the API.
