AiSensy vs PostEngage.ai — Honest Pricing Comparison
AiSensy Pricing: What You Actually Pay
AiSensy is one of India's most popular WhatsApp Business Solution Providers (BSPs), and for good reason — it launched early, built solid infrastructure, and has a large user base. But its pricing model was designed for a different era of WhatsApp marketing, when monthly subscriptions were the industry standard.
Here is AiSensy's current pricing structure as of 2026:
| Plan | Monthly Cost | Key Limits |
|---|---|---|
| Basic | ₹999/month | 2 users, basic automation |
| Pro | ₹2,299/month | 5 users, AI features add-on |
| Enterprise | ₹3,499+/month | Unlimited users, priority support |
On top of the platform fee, you also pay Meta's conversation fees directly. Marketing conversations cost approximately ₹0.58 each, utility conversations ₹0.14 each, and authentication messages ₹0.14 each. Meta provides 1,000 free service conversations per month, but outbound marketing messages are never free.
For a small business sending 500 marketing messages per month: ₹999 (platform) + ₹290 (Meta fees) = ₹1,289/month minimum. For many Indian SMBs, that is a significant recurring expense — especially when automation needs fluctuate seasonally.
What You Get Free Forever at PostEngage.ai
PostEngage.ai was built on a different pricing philosophy: the most common automation workflows should be accessible to every business, regardless of budget. That is why keyword-triggered replies are free forever on PostEngage.ai — no monthly fee, no contact limit, no expiry.
Keyword-triggered auto-replies
Set up unlimited keyword rules that fire instant responses when customers message specific words.
Multi-keyword matching
Match on "price", "cost", "rate", "how much" all in one rule — no need to create separate triggers.
Welcome messages
Auto-greet every new contact who messages your WhatsApp number for the first time.
Out-of-hours replies
Set business hours and send automated responses when your team is unavailable.
Basic flow builder
Create simple multi-step conversation flows with button menus and text responses.
Meta WhatsApp Cloud API
Official API access — no ban risk, full compliance with Meta policies.
AI-powered replies — where the system understands natural language, handles off-script questions, and maintains conversation context — use credits on a pay-per-use basis. This means you only pay for AI when you actually use it. A business that needs 200 AI replies per month pays for exactly 200 AI replies. No overpaying for a plan tier that includes features you do not need.
AiSensy vs PostEngage.ai: Feature-by-Feature Comparison
| Feature | AiSensy (₹999/mo) | PostEngage.ai (Free) |
|---|---|---|
| Keyword triggers | Yes | Yes — Free Forever |
| AI-powered replies | Pro plan only (₹2,299/mo) | Pay-per-credit |
| Broadcast campaigns | Yes | Yes |
| Multi-agent inbox | 2 users (Basic) | Unlimited seats |
| Shopify integration | Pro plan+ | All tiers |
| Meta Cloud API | Yes | Yes |
| INR billing / UPI | Yes | Yes |
| Instagram automation | No | Yes — same dashboard |
| Ban risk | None (official API) | None (official API) |
The standout differentiator beyond pricing: PostEngage.ai handles both WhatsApp and Instagram automation from one dashboard. If you run marketing across both platforms (which most Indian D2C brands do), consolidating to one tool saves additional subscription costs and reduces operational complexity.

How to Migrate from AiSensy to PostEngage.ai (Step-by-Step)
Switching WhatsApp automation platforms sounds intimidating but is actually straightforward. Your phone number and conversation history belong to Meta, not AiSensy — so migrating is really just changing which software layer sits on top of your WhatsApp Business Account.
Export your AiSensy data
Download your contact lists, message templates, and any automation flow documentation from AiSensy. Templates will need to be re-submitted since each BSP manages template approvals through their own Meta integration.
Create a PostEngage.ai account
Sign up at postengage.ai — no credit card required for the free tier. The signup process takes under 5 minutes.
Connect your WhatsApp Business Account
In PostEngage.ai, go to Settings > WhatsApp and use the Meta embed flow to connect your existing WABA. This does not affect your AiSensy integration until you choose to disconnect it.
Recreate your keyword triggers
Set up your automation rules in PostEngage.ai. Start with your highest-volume triggers first — typically price inquiries, product information requests, and booking/appointment queries.
Submit message templates
Re-submit your broadcast templates through PostEngage.ai for Meta approval. Approval typically takes 1-24 hours for standard templates.
Test and go live
Send test messages to yourself to verify all automation flows work correctly. Once confirmed, import your contact list and you are ready to switch.
When to Choose AiSensy vs PostEngage.ai
Honest answer: PostEngage.ai is the better choice for most Indian businesses in 2026, but there are specific cases where AiSensy remains competitive.
Choose PostEngage.ai if:
- Your automation is primarily keyword-triggered responses
- You also run Instagram marketing and want one dashboard

AiSensy may suit you if:
