WhatsApp has 535M+ monthly active users in India - more than Instagram and Facebook combined. Open rates are ~90% vs 20% for email. But WhatsApp marketing only works when you use the Cloud API properly, follow Meta's opt-in rules, and pick the right campaign types. Here's the ground-up guide.

Source check: verify implementation details against Meta's official WhatsApp Cloud API docs, WhatsApp pricing documentation, and message template rules.

The Cloud API (what replaced WhatsApp Business app for growth)

WhatsApp Business App (the green-icon one) is for one-person operations - 50 broadcast limit, no automation. WhatsApp Business Cloud API is the platform layer: unlimited broadcasts (with opt-in), automation, CRM integrations, and conversation-based pricing paid to Meta directly.

Conversation-based pricing (2026, India)

Marketing conversations: ~₹0.78 each
Utility (OTP, order updates): ~₹0.12 each
Authentication: ~₹0.12 each
Service (user-initiated): free for 24 hours

A "conversation" is a 24-hour window from the first message. Reply as many times as you want inside that window - still one conversation.

Template messages (the rules)

Any business-initiated message must use an approved template. Approval takes 1–4 hours. Rules:

No misleading content, no unsolicited sales pitches
Opt-in must be explicit and documented (where and when the user gave consent)
Quality Rating: Green / Yellow / Red. Red templates get paused automatically
Category must match content - Marketing templates can't be sent as Utility to save cost

The 4 campaign types that convert

Abandoned cart recovery. ~20–35% recovery rate, sent 1h + 24h + 72h after abandonment.
Post-purchase upsell. 48h after delivery with a complementary SKU. ~8–12% CTR.
Reorder reminders. For consumables - supplements, cosmetics, pet food. ~15–25% reorder rate.
Broadcast to opt-in list. Product launches, seasonal offers. ~5–10% CTR, ~90% open rate.

The tooling stack we use

Cloud API directly through Meta (cheapest)
BSP (Business Solution Provider) like Interakt, AiSensy, Gallabox if you want a UI (₹999–₹7,999/mo)
Zapier / Make / n8n for CRM webhooks
Razorpay / Shopify webhook → Cloud API for order confirmations

What to verify before acting on WhatsApp Marketing in India

Rules and platform behaviour change after an article is published. Confirm campaign policy, billing settings, attribution windows, conversion tracking, and platform changes against the Google Ads Help before you act on anything below, because the right answer depends on your entity, state, turnover, and current setup.

Frequently asked questions

Is WhatsApp marketing legal in India?

Yes, when users have clearly opted in and business-initiated messages use approved WhatsApp templates. Unsolicited scraping or bulk messaging risks blocks and compliance issues.

Do small businesses need the WhatsApp Cloud API?

Use the Business App for low-volume manual replies. Use Cloud API when you need CRM sync, automated templates, abandoned-cart recovery, broadcasts to opt-in lists, or multi-agent support.

What should be tracked in WhatsApp campaigns?

Track opt-in source, template approval status, delivery, replies, qualified conversations, conversion, unsubscribe rate, and cost per conversation instead of only open rate.
