Interakt vs loop2 for D2C sellers: templates vs free-form follow-ups

If you are a D2C owner running Meta ads, choosing between Interakt and loop2 depends on your biggest bottleneck: are you trying to blast a 10,000-person list with a discount, or are you trying to convert the 50 leads reaching out to you every day? Interakt is a powerful official API platform built for bulk broadcasts and catalogs, while loop2 is an AI sales agent designed to respond to every inbound lead and follow up until they buy.

As an interakt alternative for lead conversion, loop2 uses a linked-device mechanism to send free-form, human-like messages without needing Meta-approved templates or paying per-message fees for every follow-up.

The Real Mechanics of the WhatsApp Business API

To understand the difference between these tools, you have to understand how Meta restricts business communication. Interakt, like Wati and AiSensy, is built on the official WhatsApp Business API. This gives you high-scale power but comes with strict structural rules from Meta.

The 24-Hour Rule and Template Costs

Meta enforces a "Customer Service Window." When a customer messages your business, you have exactly 24 hours to reply with any message you want for free. Once that 24-hour clock runs out, your ability to send free-form text is locked.

To message that customer again on an API tool like Interakt, you must use a pre-approved template. In India (as of 2026), these marketing templates cost roughly ₹0.95–1.09 per message. If you want to follow up with a lead five times over a week because they stopped replying, you are paying for five separate template sends, and you cannot customize the text based on the specific questions the lead asked earlier.

The 72-Hour CTWA Window

Click-to-WhatsApp (CTWA) ads are the biggest growth driver for Indian D2C brands, with revenue from these ads growing 60% year-over-year in late 2025. When a lead clicks your ad and messages you, Meta opens a 72-hour free messaging window. During these three days, API tools don't charge for the conversation, but the moment that window closes, you are back to the ₹1+ per template rule. For high-ticket D2C items or coaching programs where the sales cycle is 7–10 days, those template costs and restrictions start to eat into the margin.

Interakt: The King of Broadcasts and Catalogs

Interakt is an excellent tool for D2C brands that have a large database and want to send mass updates. Because it uses the official API, it handles high volumes easily once you pass Meta's verification.

What Interakt does well:

• Bulk Broadcasts: You can send a discount code to 5,000 customers at once.
• Product Catalogs: You can sync your Shopify catalog so users can browse products inside WhatsApp.
• Interactive Buttons: You can use "Quick Reply" buttons and list menus to help users navigate.
• Team Dashboard: A shared inbox where multiple agents can chat with customers.

However, Interakt is bound by API limits. You cannot use it on your existing phone app; you must move your number to the API, which deletes your chat history and removes your ability to use the green WhatsApp app on your phone. Most importantly, Interakt cannot "chat" on its own to convince a lead—it can only send the templates you've pre-designed and scheduled.

loop2: The AI Sales Agent for Inbound Leads

loop2 is not a broadcasting tool. It is an AI agent that lives on your existing WhatsApp number (Business or Personal) as a linked device. While standard WhatsApp allows 4 linked devices, loop2 connects as one of these slots to act as your virtual sales assistant.

Because it doesn't use the API, loop2 is not restricted by the 24-hour window or the ₹1/template cost. It writes every follow-up from scratch based on the lead's unique objections. If a lead says, "I'm worried about the delivery time to Assam," loop2 understands that, answers it, and then follows up two days later specifically asking if they are ready to ship to Assam.
