Interakt vs Wati vs AiSensy: what WhatsApp marketing really costs a D2C brand

How does WhatsApp API pricing actually work in 2026?

Every WhatsApp marketing bill has two layers: Meta’s charges for the messages themselves, and your platform’s charges — a subscription, a per-message markup, or both. Since 1 July 2025, Meta bills per delivered template message, not per 24-hour conversation, and the rate depends on the message category: marketing (promos, offers), utility (order updates), authentication (OTPs) and service (free-form replies to customers, which are free). One detail worth real money: utility templates delivered inside an open 24-hour customer-service window are free — so order updates sent while a customer is actively chatting cost nothing.

What do Interakt, Wati and AiSensy cost?

Interakt (Jio Haptik’s platform) is the value anchor: India plans have typically run around ₹999/month for Starter — with the catch that monthly-billed Starter covers Instagram only, and WhatsApp access needs quarterly or annual billing — about ₹2,499/month for Growth and ₹3,499/month for Advanced, with Enterprise on request. Its India rate card lists marketing at ₹0.958, utility at ₹0.150 and authentication at ₹0.128 per message — and its own Enterprise plan advertises “no template markups”, which tells you the lower tiers carry them.

Wati is the multi-agent inbox specialist and the priciest of the three: its international site lists Growth at $99/month, Pro at $299 and Business at $999 (roughly 25% less billed annually), with 3–5 users included and extra seats at $24–69. India-billed pricing has typically run materially lower — Growth around the ₹2,500/month mark per 2026 comparisons — so get a current INR quote. Messages are billed “on the Wati rate card”, i.e., marked up over Meta’s base rates; third-party analyses commonly peg the markup at 15–20%.

AiSensy inverted the model: the base platform is free with unlimited users, and you prepay for messages instead — its published India card (effective 1 January 2026) lists marketing at ₹1.09 and utility/authentication at ₹0.145 per message. The paid pieces are add-ons: a drag-and-drop chatbot builder at ₹2,500/month, an AI agent builder at ₹3,500/month, and an Indian virtual number at ₹2,000/year.

Where does the markup actually hide?

In the per-message rate, not the subscription. Run 50,000 marketing messages a month: Meta’s base is ₹43,155. At Interakt’s listed ₹0.958 you pay ₹47,900; at AiSensy’s ₹1.09, ₹54,500 — a ₹6,600/month spread that dwarfs the difference between any two subscription tiers. And note the irony: platforms marketing “no markup” the loudest still publish cards above Meta’s raw rate, because GST treatment, FX handling and rounding all get baked in differently. So ask every vendor one identical question: what is my all-in, GST-inclusive price per delivered marketing message — and per utility message, inside and outside the service window? Utility markups matter more than they look: for a shipping brand, order updates and COD-confirmation flows that cut RTO quickly outnumber campaign blasts, and WhatsApp’s benchmark economics only hold if the per-message cost stays honest.

What about free tiers, trials and coexistence?

Free-to-start honestly ranked: AiSensy wins (no subscription at all, ₹50 of test credits), Interakt offers trials and a cheap entry tier, Wati gives seven days. The newer question is coexistence — Meta’s 2025-rolled-out feature that lets the WhatsApp Business app and the API run on the same number, so a founder can keep chatting from the phone while campaigns and automations run on the platform. It is live in India (Business app v2.24.17+ and a verified Meta business required). Wati supports it, AiSensy supports it with assisted onboarding, and with Interakt you should confirm current status before migrating a number. If your entire retention plan lives on one founder phone today, coexistence removes the scariest part of moving to the API — losing the chat history and the habit.

Your WhatsApp bill is a media bill. Negotiate it like one — per message, all-in, GST included.

Which platform suits which D2C brand?

• Founder-run, under ~10,000 messages a month: AiSensy’s free platform is the obvious start — your entire cost is the message card, and unlimited seats mean the whole team can answer chats.
• Shopify D2C leaning on commerce flows: Interakt’s catalog, payments and abandoned-cart plumbing plus the lowest listed marketing rate of the three make it the value pick — push for Enterprise’s no-markup terms once volume justifies it.
• Support-heavy or multi-brand teams: Wati’s inbox, routing and no-code automations are the most mature — but price the rate-card markup at your real volume before signing, because it compounds invisibly.
• Broadcasting at serious scale: whoever you pick, the negotiation is per-message. A ₹0.10 difference at 200,000 marketing messages a month is ₹2.4 lakh a year — real media money that should be earning, not leaking, and it belongs in the same P&L review as your paid media programme. WhatsApp works best as the retention layer of that system, not a standalone bill nobody audits.
