Based on usage insights from Interakt’s platform, SMBs using WhatsApp for marketing and customer service achieved:

• 98% message open rates (vs. 25% email average)

   

• 32% CTRs on campaign messages

   

• 20% higher repeat purchase rates when using AI-powered workflows

In this benchmark report, we explore how top SMBs are using the WhatsApp Business API to engage customers across the marketing funnel – from awareness to retention, and what trends will define conversational commerce in 2025.

Building Awareness Through WhatsApp Campaigns

At the top of the funnel, brands are using WhatsApp for personalized marketing campaigns that drive discovery and awareness. Instead of relying solely on ads or email, WhatsApp enables instant, interactive connections.

Key trends:

• Personalized Broadcasts: SMBs segment users based on demographics, location, or purchase behavior.

   

• Product Launch Alerts: Timely updates sent through the WhatsApp Business API see higher engagement than traditional channels.

   

• Ad Integration: Click-to-WhatsApp (CTWA) ads on Facebook and Instagram convert up to 3x better than standard ad formats.

   

For instance, many eCommerce brands using Interakt’s WhatsApp marketing automation have integrated CTWA ads with dynamic catalog messaging, driving traffic directly into personalized product conversations.

Nurturing Leads and Driving Conversations

In the middle of the funnel, WhatsApp becomes a nurturing channel — helping brands build trust through timely follow-ups, content sharing, and guided buying assistance.

Benchmark insights from Interakt users (2024-25):

• Businesses sending educational messages (how-tos, care tips, FAQs) saw 1.8x higher retention.

   

• Automated follow-ups within 24 hours increased conversion probability by 27%.

   

• Campaigns that used segmentation + personalization achieved the highest CTRs.

   

Top SMBs are combining automation and human support through AI chatbots powered by the WhatsApp Business API, creating seamless, conversational experiences. From booking demos to collecting reviews, the key is relevance and timing.

Example: A D2C skincare brand used Interakt’s AI Workflows to send quiz-based product recommendations, achieving 4x more responses compared to static ads.

Converting Leads and Retaining Customers

At the bottom of the funnel, WhatsApp excels at driving conversions and post-purchase engagement. Brands using WhatsApp Business API integrations with CRMs and payment gateways are seeing measurable impact on ROI.

High-performing strategies in 2025:

• Cart Recovery Reminders: Automated messages sent within 30 minutes of abandonment convert 18–25% of carts.

   

• Order Tracking & COD to Prepaid Nudges: WhatsApp notifications reduce RTO rates significantly.

   

• Payments on WhatsApp: Integration with Razorpay and PayU via Interakt enables in-chat checkout experiences.

   

By consolidating customer communication, order updates, and payments in one chat, businesses enhance trust, convenience, and retention.
