A proven method for e-commerce businesses to recover lost sales through intelligent WhatsApp automation

Every day, 70% of e-commerce carts are abandoned, representing billions in lost revenue. While traditional email recovery achieves only a 20% open rate, WhatsApp messages boast an impressive 98% open rate, making them the ultimate channel for cart recovery.

Wassenger Flows brings n8n-style visual automation directly inside the Wassenger platform. No more juggling multiple tools or complex API setups. Create sophisticated abandoned cart recovery automations that combine AI with WhatsApp’s unmatched engagement rates, all within a single platform.

Wassenger Flows: n8n Power, Zero Complexity

Traditional cart recovery requires a complex tech stack: webhook services, automation platforms like n8n, multiple API integrations, and separate WhatsApp solutions. Wassenger Flows eliminates this complexity by providing visual workflow building directly inside your Wassenger dashboard.

Key Advantages:

• Visual Interface: Build automations using intuitive drag-and-drop, just like n8n
• Native WhatsApp: Simply connect your WhatsApp to Wassenger — no separate API setups
• Built-in AI: Integrated agents analyse cart data and create personalised messages
• All-in-One: Complete automation without external tools or integrations

The entire flow works seamlessly: Shopify webhook → AI analysis → Personalised WhatsApp message → Smart logic prevents duplicate messaging.

Building Your Cart Recovery Flow: Step-by-Step

Step 1: Shopify Integration

Configure your Shopify webhook for “cart/update” events. In Wassenger Flows, add a Shopify Trigger node with validation rules: email exists, items in cart, and being inactive for 2+ hours. This prevents triggering on active shopping sessions.

Pro Tip: The 2-hour rule prevents annoying customers who are still actively shopping. Only truly abandoned carts trigger the recovery flow.

Step 2: Cart Validation with IF Node

What you’ll do: Add logic to ensure we only process genuinely abandoned carts.

The first IF node validates three critical conditions:

• The customer's email is present
• The cart contains at least one item
• The cart has been inactive for 2+ hours

This prevents the flow from running unnecessarily and ensures compliance with messaging best practices.

Step 3: AI-Powered Analysis

What you’ll do: Let AI determine if recovery messaging is appropriate.

The AI Cart Recovery Agent performs intelligent analysis:

• Extracts cart token/ID from Shopify data
• Uses Shopify tools to check if the cart converted to an order
• Prevents messaging customers who have completed purchases
• Analyses product data for personalisation
• Creates contextual recovery messages

Example AI-generated message: “Hi Sarah! Your Wireless Headphones Pro are still waiting. Respond Yes and get free shipping!”

Step 4: Phone Number Validation

What you’ll do: Ensure WhatsApp delivery is possible before attempting to send.

After the AI analysis, the second IF node performs the most critical check, verifying that the customer’s phone number exists in Shopify data.

The three validation conditions are:

1. send_message = true (AI-determined messaging is appropriate)
2. cart_abandoned = true (AI confirmed no order exists)
3. customer_phone is not empty (This is crucial!)

🚨 Requirement: If your Shopify checkout doesn’t collect phone numbers, this automation will not work. The customer phone number must be present in Shopify’s customer data for WhatsApp delivery to succeed.

Step 5: WhatsApp Message Delivery

• What you’ll do: Send the personalised recovery message via WhatsApp.
• When all conditions are met, the Send WhatsApp Recovery Message node:
• Formats phone numbers automatically (international format)
• Delivers the AI-generated personalised message
• Handles WhatsApp API compliance automatically
• Provides real-time delivery tracking
