AiSensy vs Wati vs loop2: Choosing the Right WhatsApp Tool for Meta Ads
Choosing between AiSensy vs Wati depends on whether you need a broadcast dashboard or a sales agent. We break down the mechanics of the 24-hour window, template costs, and CTWA strategy for Indian sellers.
If you are running Click-to-WhatsApp (CTWA) ads in India, the choice between AiSensy vs Wati or loop2 depends on one metric: how fast you close the lead. Wati and AiSensy excel at broadcasting catalogs to thousands of users, while loop2 functions as an AI sales agent that handles the actual conversation to ensure no lead goes cold.
Meta reported that click-to-WhatsApp ads revenue grew 60% year-over-year in Q3 2025, and India remains the largest market for this format. For a D2C seller or a coaching institute, every ad click captures the lead's phone number instantly. However, the profit is made or lost based on the 24-hour customer service window and how you manage follow-ups once that window shuts.
The Mechanics of the WhatsApp Business API
To understand AiSensy vs Wati, you must first understand the official WhatsApp Business API rules. Unlike the standard WhatsApp app or the Business app (which allow 4 to 10 linked devices), the API is a different engine.
The 24-Hour and 72-Hour Windows
When a user messages your business, a 24-hour customer service window opens. Within this time, you can reply with free-form text and media for free. Every time the customer sends a new message, this timer resets. However, if 24 hours pass without a customer reply, moving forward requires a pre-approved template message.
For advertisers, Meta offers a massive advantage: Click-to-WhatsApp ads open a 72-hour free messaging window. This gives you three full days to convert a lead without paying per-message fees, provided the conversation started from an ad click.
Template Pricing in India (2026)
As of July 1, 2025, Meta moved to per-message pricing. In India, marketing templates—the ones you use to nudge a lead to buy—cost roughly ₹0.95–1.09 per message. Utility and authentication messages are cheaper, at roughly ₹0.115–0.145.
| Feature | Official API (Wati/AiSensy) | Standard/Business App |
|---|---|---|
| Linked Devices | Unlimited (via Dashboard) | 4 to 10 (Premium) |
| Groups | Not Supported | Supported |
| Broadcasts | Unlimited (Tier-based) | Limited to 256 (Labels) |
| Follow-up | Templates only after 24h | Free-form always |
| Account Cap | 250/day if unverified | No specific cap |
AiSensy: The Marketing Specialist
AiSensy is built for the marketer who wants to send high-volume broadcasts. They enable you to import a contact list and blast marketing templates to thousands of users at once.
What AiSensy does well:
- Smart Campaigns: You can segment your audience based on tags and schedule broadcasts for festive sales.
- Template Management: They provide a clean interface to submit templates for Meta's approval (which usually takes minutes to a few hours).
- Product Catalogs: Excellent integration for D2C brands to showcase items directly in the chat.
However, AiSensy is a tool, not a salesperson. It provides the dashboard, but your team still has to handle the incoming messages or you have to build complex, rigid chatbots to do it for you. If your team takes 30 minutes to reply to a CTWA lead, research shows your conversion probability drops significantly compared to a 5-minute response.
Wati: The Customer Support Veteran
Wati is one of the oldest players in the space and is widely used by customer support teams. Like AiSensy, it is built on the official API, meaning it inherits the same structural limits: no groups, a dedicated new number, and no chat history migration from your old phone app.
What Wati does well:
- Shared Inbox: A robust team inbox where multiple agents can jump in to solve customer queries.
- Interventions: It allows for easy manual takeover when a chatbot gets stuck.
- Integrations: Strong hooks into CRMs like Zoho or HubSpot.
Wati is great for managing existing customers, but for a seller running aggressive Meta ads, the delay in human response time can lead to massive lead drop-off.
The Problem: The "Lead Silence" Gap
Both AiSensy and Wati focus on the "Broadcast" (one-to-many) and the "Dashboard" (many-to-one). The gap for a growing SME is the "Conversation" (one-to-one).
When a lead clicks your ad at 11:00 PM, they expect an answer now. In India, over 60% of WhatsApp users message a business weekly, and the median purchase happens within about an hour of the first message. If you are relying on a human agent to log into a Wati dashboard the next morning, that lead is likely gone.
While templates can be sent later, Meta applies per-user frequency caps on marketing templates. You cannot spam a lead who didn't reply. This is where loop2 changes the dynamic by acting as an AI sales agent that stays awake 24/7 to qualify and close leads immediately.
Scale Limits and Verification
If you are a new seller, you can start on the API without Meta Business Verification. However, you will be capped at 250 business-initiated conversations per day. This means you can only send templates to 250 new people every 24 hours. To scale your ads and notifications, you must verify your business with legal documents.
According to the GoKwik WhatsApp Commerce Intelligence Report 2026, brands using automated journeys saw 2.25x higher median GMV growth. This growth wasn't just from sending more messages, but from the 11.1% CTR achieved through automated journeys versus just 2.6% for standard broadcasts.
Comparing AiSensy vs Wati vs loop2
Choosing the right partner depends on your specific bottleneck:
- Choose AiSensy if: Your primary goal is sending 50,000+ marketing broadcasts a week and you have a settled team to handle the replies.
- Choose Wati if: You have a large customer support team that needs a stable, shared inbox to manage existing tickets.
- Choose loop2 if: You are spending money on Meta ads and losing money because your team cannot reply to every lead within 5 minutes, 24/7.
loop2 doesn't just give you a dashboard; it lives on your existing WhatsApp number — not the API — so it answers instantly and keeps following up in natural language even after the 24-hour window closes, when API tools are limited to rigid templates.
Conclusion: Which one for your Meta Ads?
For an Indian SME, the math is simple. If you pay ₹50 per lead on Meta ads, you cannot afford to let that lead sit for 2 hours. While Wati and AiSensy provide the infrastructure to send and receive messages, the "intelligence" of what to say to a skeptical buyer is still left to you.
If you need a robust catalog and broadcast engine, Wati or AiSensy are the market standards. If you need to turn those expensive ad clicks into actual sales without hiring five more agents, you need an AI sales agent designed for conversion.
Loop2 solves the lead response problem by ensuring every CTWA click is greeted, qualified, and nurtured by an AI agent that understands your products.
