Businesses are moving beyond generic WhatsApp broadcasts and shifting toward micro-segmentation, a personalised messaging approach that groups customers based on their behaviour, actions, intent, and lifecycle stage. This shift is largely powered by the WhatsApp Business API, CRM integrations, and advanced platforms like Interakt.

In this guide, we’ll explore how brands can build micro-segments, automate them, and convert more customers across TOFU, MOFU, and BOFU, with a step-by-step breakdown.

 

What Is Micro-Segmentation on WhatsApp?

 

Micro-segmentation is the process of dividing your audience into extremely specific groups using:

 

  • User attributes (location, preferences, age group)

     

  • Behavioural data (clicks, sessions, funnel drop-offs)

     

  • Purchase intent (COD orders, cart value, product category)

     

  • RFM scoring (recency, frequency, monetary value)

     

  • CRM tags (lead status, pipeline stage)

     

The WhatsApp Business API enables you to send personalised messages to these segments at scale, something the WhatsApp Business App alone cannot do.

 

Why Micro-Segmentation Boosts Sales 2–3x

 

Brands using CRM + WhatsApp Business API segmentation see:

✔ Higher CTR (20–50%)

Hyper-personalised campaigns outperform generic broadcasts.

✔ Increased conversion rates (2–3x)

Segmented offers match customer intent → faster purchases.

✔ Lower ad spend

Re-engaging warm segments via WhatsApp costs far less than running new ads.

✔ Reduced RTO

COD-to-prepaid nudges based on risk segments significantly reduce returns.

Step-by-Step Guide: How to Create Segments Using WhatsApp Business API + CRM

Step 1: Identify Relevant Data Points

Using your CRM (e.g., Interakt’s WhatsApp Sales CRM), pull data from:

 

  • Website analytics

     

  • Purchase history

     

  • WhatsApp conversation logs

     

  • UTM parameters

     

  • Payment history

     

  • RFM scoring

     

This automatically creates a 360° customer profile—the foundation of segmentation.

Step 2: Build Micro-Segments

Examples:

 

1. High-value repeat buyers

 

Filters:

 

  • AOV > ₹2000

     

  • Purchased 3+ times

     

  • Last purchase < 60 days

     

2. COD risk users

 

Filters:

 

  • COD preference + frequent RTO

     

  • Long delivery time zones

     

  • High-value order

     

3. Price-sensitive prospects

 

Filters:

 

  • Clicked offers

     

  • Viewed discounts

     

  • Abandoned cart during sale

     

4. Category-specific interest groups

 

Filters:

 

  • Viewed skincare > 3 times

     

  • Added clothing items to wishlist

     

  • Engaged with the size guide

     

5. New WhatsApp Leads from CTWA ads

 

Filters:

 

  • Channel = CTWA

     

  • No purchase yet

     

  • Dropped after 1 conversation

Step 3: Automate Flows for Each Segment

Using the WhatsApp Business API automation engine in Interakt:

 

  • Send abandoned cart reminders

     

  • Trigger post-purchase cross-sell flows

     

  • Convert COD → prepaid automatically

     

  • Engage new leads with guided shop flows

     

  • Nurture inactive users with winback campaigns

     

The automation ensures the right message goes to the right user at the right time.

Step 4: Personalise Content

Use dynamic fields to personalise:

 

  • Name

     

  • Product viewed

     

  • Cart value

     

  • Recommendations

     

  • Locations

     

  • Discount codes

     

Example:

 

“Hey Aditi! You were checking out our Vitamin C Serum. Want a 10% discount?”

Step 5: Analyse Segment Performance

Track:

 

  • Delivery rates

     

  • Conversions

     

  • Payment completions

     

  • Revenue generated per segment

     

  • CTR and response rate

WhatsApp Business API Pricing: Why Segmentation Matters

Since WhatsApp charges per conversation category, segmentation helps you:

 

  • Suppress irrelevant users

     

  • Send fewer but more impactful messages

     

  • Use utility or marketing templates effectively

     

  • Increase revenue per message sent

     

This directly improves WhatsApp Business API ROI.

 

Integrations That Improve Segmentation Accuracy

 

  • Shopify

     

  • WooCommerce

     

  • Razorpay

     

  • PayU

     

  • Cashfree

     

  • Zoho/HubSpot CRM

     

  • Google Sheets

     

  • Meta CTWA Ads

     

These integrations feed data back into Interakt, enhancing your segmentation engine.

 

Micro-segmentation is no longer optional; it’s the only way to scale personalised commerce on WhatsApp. With the WhatsApp Business API, CRM-powered insights, and tools like Interakt and Interakt’s WhatsApp Sales CRM, brands can automate their entire funnel, reduce marketing waste, and convert more customers with targeted messaging.
