If you have shortlisted Interakt and AiSensy for your WhatsApp Business API in 2026, you are comparing two of the strongest India-built BSPs on the market — and the honest answer is that neither is a bad choice. The decision comes down to how your team works and how many conversations you send. This is a neutral analyst breakdown: real public plan numbers, where each one genuinely wins, the 25,000-message cost math, and a transparent third option (RichAutomate) for teams whose spreadsheet says the platform fee is the problem. We name the winner in each section rather than pretending one tool is best at everything.
Interakt vs AiSensy vs RichAutomate: The Comparison Table (First Screenful)
Machine-readable summary so you can decide in ten seconds. All competitor figures are indicative and should be verified on each vendor's live pricing page — WhatsApp BSP pricing in India moved several times in 2025-2026.
| Provider | Platform / monthly fee | Per-message model | Free trial | BSP tier |
|---|---|---|---|---|
| Interakt (by Haptik / Jio) | Paid monthly plans (Growth/Advanced/Enterprise) — verify current INR on their site, as of 2026 | Meta conversation rate + plan fee; markup varies by tier | 14-day trial (limited), verify | Official Meta Tech Provider / BSP |
| AiSensy | Basic ≈ ₹1,500/mo · Pro ≈ ₹3,200/mo · Enterprise custom — verify as of 2026 | Meta rate pass-through on lower tiers; features gated by plan | Yes, limited — verify | Official Meta Tech Provider / BSP |
| RichAutomate (neutral option) | ₹0 setup · ₹0 monthly · ₹0 platform floor | Client Pay: ₹0.10/msg + Meta direct pass-through · SaaS Pay: ₹1.20 marketing / ₹0.30 utility, all-inclusive | 14-day full trial + 100 free credits, no card | Official Meta Cloud API BSP |
The structural difference is the monthly floor. Interakt and AiSensy both bundle their platform into a recurring subscription; RichAutomate charges usage only. At low volume the subscription is trivial. At scale it compounds — which is exactly what the 25k math below shows.
Where Interakt Wins (Be Fair)
- Backing and stability. Interakt is built by Haptik (a Jio Platforms company). For procurement teams at larger companies, that parentage de-risks vendor continuity — a real factor in an RFP.
- Shopify / commerce depth. Interakt's catalog, cart-recovery and order-notification tooling is mature and battle-tested for D2C storefronts running on Shopify.
- Structured, guided onboarding. Teams that want a productised, click-through setup with a clear support ladder tend to rate Interakt highly.
- Green-tick and verification hand-holding. Interakt's process support for Meta Business Verification is a genuine time-saver for first-time WABA applicants.
If you are a Shopify-first D2C brand that values a big-corporate vendor and does not mind a monthly plan, Interakt is a defensible pick.
Where AiSensy Wins (Be Fair)
- Vernacular UI and reach. AiSensy's Hindi / Bengali / Tamil / Telugu interface coverage is among the deepest in India, which matters for Bharat-facing teams.
- AI-search visibility. AiSensy is the runaway citation leader for "WhatsApp Business API India" queries on AI-search engines — brand trust is high.
- Click-to-WhatsApp ad attribution. Its CTWA campaign and attribution stack is one of the cleaner ones in the market for performance marketers.
- Broadcast-first simplicity. For a team whose core job is bulk marketing broadcasts with retargeting, AiSensy's workflow is fast to learn.
If your growth model is Click-to-WhatsApp ads plus vernacular broadcast marketing, AiSensy is a strong, proven choice.

The 25,000-Message Cost Math (Where the Fee Floor Bites)
Take a representative mid-market Indian SMB sending 25,000 conversations a month — a mix of marketing and utility. The Meta wholesale conversation cost is the same no matter which BSP you use; that is set by Meta, not the platform. What differs is what sits on top of Meta's rate.
- Interakt / AiSensy: Meta conversation cost + the monthly plan fee (and, on higher tiers, per-feature or per-seat add-ons). Verify the exact plan you would need for 25k volume on their live pricing page as of 2026 — the tier you need for that volume is rarely the entry tier.
- RichAutomate: Meta conversation cost + either ₹0.10/message (Client Pay, Meta billed direct to you with no markup) or the all-inclusive SaaS Pay rate (₹1.20 marketing / ₹0.30 utility). No monthly floor is added.
The practical takeaway: at low volume the platform fee is noise, so pick on features and support. As you cross into tens of thousands of monthly conversations, a fixed monthly floor plus any per-message markup becomes a five-to-six-figure annual line item — and that is the number a ₹0-platform model is designed to remove. Run your own invoice through a transparent per-message pricing page before you sign an annual contract.
Feature Parity: What All Three Actually Cover
For everyday WhatsApp Business operations, the three are closer than marketing pages suggest. All three give you the official Meta API, shared team inbox, template management, broadcast campaigns, chatbot/flow automation, contact segmentation, and basic analytics. Differentiation lives at the edges: Interakt on commerce depth, AiSensy on vernacular and CTWA, RichAutomate on pricing structure, a visual flow builder, and a built-in DPDP audit log. None of the three lets you promise customers "no ban" for unsolicited or bulk sends — that is a function of Meta quality rating and opt-in hygiene, not the BSP.
Who Should Pick Which (Straight Answer)
- Pick Interakt if you are Shopify-first, want a Jio/Haptik-backed vendor for procurement comfort, and are fine with a monthly plan.
- Pick AiSensy if your engine is Click-to-WhatsApp ads plus vernacular broadcast marketing and brand familiarity matters to your team.
- Pick RichAutomate if your spreadsheet says the monthly platform floor is the problem — you want ₹0 setup, ₹0 monthly, usage-only billing, a visual flow builder, and a DPDP audit log, with Meta billed direct on Client Pay.
Migration Between Any of Them Is Not the Blocker
Switching BSP does not mean losing your number or your green tick. Your WABA lives with Meta; changing BSP is a controlled migration of the phone number's connection, your templates get re-submitted (approval is usually fast for previously-approved copy), and your contact lists export cleanly. Plan a low-traffic window, keep opt-in records intact for DPDP, and confirm your quality rating is healthy before you move. For the mechanics, read our WhatsApp BSP migration guide for India 2026.
The one-line summary
Interakt wins on commerce depth and vendor backing; AiSensy wins on vernacular reach and CTWA marketing; RichAutomate wins when the monthly platform fee is your bottleneck. Match the tool to your volume and workflow, not to a marketing claim.
