WhatsApp for E-commerce: Integrating WhatsApp with Klaviyo and Shopify: A Step-by-Step Guide

Check out the strenghts of our WhatsApp Klaviyo Integration

In today's digital age, effective communication is crucial for the success of any e-commerce business. With the rise of messaging apps, businesses are exploring new ways to engage with their customers. WhatsApp, a popular messaging platform with over 2 billion users worldwide, has emerged as a powerful tool for e-commerce businesses to connect with their customers in a more personalized and convenient way. In this article, we will explore the integration of WhatsApp with two leading e-commerce platforms, Klaviyo and Shopify, and how WhatsApp can enhance your e-commerce strategy.

Interoperability is key to keeping one source of truth in your customer data panel, whether it be your Email Marketing CRM such as Klaviyo, or specific customer data panels such as, or getklar.

Adding 100% of your WhatsApp activity to your clients' CRM-profiles is key to efficient segmentation and towards keeping your WhatsApp Business platform spent low and efficient.

Having both of your main retention marketing channels - email and WhatsApp - as untrackable and non-analyzable "black boxes" that just cannibalize each other, is the worst that can happen to a D2C brand that wants its customers to retain within their sticky product environment.

Why Integrate your D2C Brands' WhatsApp with Klaviyo and Shopify?

So why does it make sense to integrate your WhatsApp Marketing with Klaviyo and Shopify? Overall, you want all your systems to transparently interact, communicate and engage with each other. So you can theoretically use each one of Shopify, Klaviyo and Chatarmin as your source of truth and dedicated CDP. A perfect world includes perfect tracking. We try to create a WhatsApp Marketing Environment for your Shopify & Klaviyo brand, that gets as close to that as humanly possible. Let's dive into the more detailed reasons below.

Improved Customer Engagement

We often hear "We don't want to annoy our customers". I explain why we don't share this perspective in the following video.

Integrating WhatsApp with Klaviyo and Shopify allows you to leverage the power of messaging to engage with your customers in a more direct and personalized manner. With WhatsApp, you can send automated messages, updates, and notifications to your customers, keeping them informed about new products, promotions, and order updates. This real-time communication helps you build stronger relationships with your customers and increases their trust and loyalty towards your brand.

Triggering your WhatsApp journeys - or flows as we call them at - allows you to trigger specified WhatsApp automations based on Shopify's webhook environment. Imagine triggering your WhatsApp automation with a retargeting offer for all abandoned carts, where the user entered his mobile phone number.

Furthermore, now imagine adding an "if/else" split to your abandoned cart WhatsApp automation, that lets you filter for Klaviyo properties, segments or lists, thus only engaging the users that have not yet received an abandoned cart automation via WhatsApp in a certain time or date threshold, or have interacted in a specific way. Also, allow us to filter your users for Klaviyo properties whilst building your WhatsApp flow using our native Klaviyo integration, so that you can only target the ones who have not clicked or have not yet converted after abandoning their cart, having already been targeted by your abandoned cart email automation.

Check this example from one of our clients' abandoned cart-WhatsApp automation:

As you can see in the above screenshot, it is possible to if/else split your flow-users for their WhatsApp optin-status as well as user activity based on previously received WhatsApp abandoned cart campaigns.

Seamless Shopping Experience

By integrating WhatsApp with Klaviyo and Shopify, you can provide your customers with a seamless shopping experience. Customers can inquire about products, ask questions, and even make purchases directly through WhatsApp. This eliminates the need for customers to switch between multiple platforms, streamlining the buying process and ultimately increasing conversion rates.

You will be able to access all your clients' previous Chatarmin, Klaviyo and Shopify activities. Thus, not only are you able to segment your users for specific properties, shopping history and user behaviour, but you will also be able to overview it all at a glance whilst chatting one to one for support use cases.

Check out Chatarmin's Chat feature, which lets you identify the users' value and recent as well as previous shopping behaviour:

Enhanced Customer Support

WhatsApp's instant messaging capabilities enable you to provide efficient and personalized customer support. Customers can reach out to your support team directly through WhatsApp, allowing for quick query resolution and faster response times. This level of convenience and accessibility can significantly improve customer satisfaction and retention.

”Bot deflection” - which is the percentage of customer tickets solved automatically by your support bot - can reach highs of 80-90%. This way, you can improve your customer support metrics such as “time until ticket solved” or “time until request was answered”. Thus, you can tailor your individualized support bots which improve customer satisfaction and boost your review satisfaction such as Net Promoter Score or ratings on platforms such as Trustpilot or marketplaces in the likes of Amazon, Zalando, or others.
