Which WhatsApp BSP has the cheapest entry tier?

PostEngage.ai is the cheapest at ₹0/month for keyword automation forever. Among traditional BSPs, AiSensy Basic at ₹999/month is cheapest, followed by Interakt Growth at ₹1,999. Wati Standard ($39) and Respond.io Starter ($79) are the most expensive entry tiers.

Which plan tier should an Indian SMB pick?

For pure keyword automation, PostEngage.ai free plan covers most SMB needs (unlimited rules, agents, templates). If you need a built-in CRM and richer template management, AiSensy Pro at ₹2,399 or Interakt Growth at ₹1,999 are reasonable steps up. Skip Wati unless you specifically need its agency partner program.

How does PostEngage.ai monetise if keyword replies are free?

AI-generated personalised replies are billed via INR credit packs. 100 free credits at signup. Customers buy more credits as their AI-driven automation scales. Keyword replies stay free because they are cheap to serve and anchor the relationship.

Does Wati offer better features than AiSensy at higher tiers?

Wati Premium adds advanced analytics, custom roles, and webhooks, but AiSensy Enterprise at ₹3,499 offers similar features at less than half the dollar-adjusted Wati Premium price. For Indian businesses, AiSensy tends to win on features-per-rupee.

Are there volume discounts on Meta conversation fees?

Meta itself does not publish volume discounts on conversation fees — the rate card applies uniformly. Some BSPs negotiate enterprise discounts for >100k conversations/month, but these come with annual commitments and are not relevant for SMB plans.

How do per-user fees stack at higher tiers?

Wati charges per-teammate beyond the included seat count on every tier. Respond.io similarly tiers users. AiSensy and Interakt include generous seat counts. PostEngage.ai has zero per-user fees on any plan.

Does any plan include DPDP-compliant features by default?

PostEngage.ai includes Indian data residency, opt-in tracking, and audit logs on the free plan. AiSensy and Interakt include them at Pro tier. Wati and Respond.io require enterprise plans for full DPDP-grade controls.
