Klaviyo WhatsApp Integration Guide

Automated messages and interactions with your customers increase satisfaction when they can choose their own touchpoints. Audience selection is no longer just based on purchase behavior data but also on the type of communication your customer prefers.

What Can the Klaviyo WhatsApp Integration Do?

Integrating WhatsApp into your e-commerce channel alongside Klaviyo can strengthen and complement your campaigns, offering users the customer journey they’re used to or expect from you.

The potential of combining email and WhatsApp should be fully leveraged for your business’s benefit, allowing you to:

Send notifications in the way that offers your customer the easiest access.
Campaigns can, for example, use a WhatsApp message to streamline sales flows, while order updates still land in the customer’s email inbox.
Klaviyo, together with the Chatarmin platform, enables you to merge data from various integrated channels and target each defined segment individually to improve customer lifetime value.
As a marketing automation platform, Klaviyo combined with WhatsApp brings together two very different communication channels. The customer experience is strengthened and your team—especially in support—is relieved.

Benefits of the Klaviyo WhatsApp Integration from Chatarmin

Integrating WhatsApp into your e-commerce channel with Klaviyo can optimize your campaigns and create a seamless customer journey. The combination of email and WhatsApp enables targeted customer communication and improves customer lifetime value.

With Klaviyo and Chatarmin, you can send notifications and campaigns via your customer’s preferred channel. WhatsApp increases sales and engagement rates, while emails continue to be used for order summaries and updates.

The platform allows for targeted segmentation and communication with specific customer groups, strengthening the customer experience and relieving your support team. This automation improves marketing workflows and maximizes campaign success.

Is the WhatsApp-Klaviyo Integration Right for Your Business?

WhatsApp was once thought to replace email in sales and marketing. But that was a short-sighted view—popular channels that drive revenue should never be withheld from your customers.

Instead, it has become clear that combining email and WhatsApp marketing improves customer service and determines strategy and engagement across your marketing, sales, and support teams.

Since WhatsApp Business API comes with costs, why risk your existing email contact for WhatsApp? The answer often lies in open rates.

How to Integrate Klaviyo with WhatsApp Using Chatarmin

Log in to your Klaviyo account.
Click “Account” in the upper-right menu under your account name.
Go to 'Settings' > 'API KEYS'
Click 'Create Private API Key'.
Give your private API key a name, select 'Full Access Key', and click 'Create'. You must create a full access key to grant Chatarmin the necessary admin rights.
Enter this API key on the Klaviyo Integration page on Chatarmin.

Done! That’s how easily you can complete your Klaviyo WhatsApp integration with Chatarmin.

Use Cases After Successfully Integrating Klaviyo and WhatsApp

Numbers and facts are essential for decision-making in your company. Merging customer data and considering WhatsApp as a Klaviyo integration is a smart move.

Use cases highlight the value of this integration. WhatsApp, Klaviyo, Chatarmin, and your shop system offer the following advantages:

Trigger Chatarmin Flow from Klaviyo Flow

You can trigger a Chatarmin flow from a Klaviyo flow using a webhook. This allows you to re-engage customers who no longer respond to emails—for example, by triggering a WhatsApp flow after five unopened emails.

React to Klaviyo Events

In Chatarmin, you can also set “Klaviyo Events” as flow triggers. Event properties from Klaviyo can be filtered here as well.

Klaviyo Flow Actions

Chatarmin also provides two flow actions from Klaviyo:

Update Klaviyo Profile
Sub-/Unsubscribe List

Update Klaviyo Profile

This allows you to automatically add properties to a Klaviyo profile based on user behavior. Depending on which workflow branch a user follows, their profile can be updated with custom properties.

Sub-/Unsubscribe List

Depending on user activity, you can directly subscribe or unsubscribe a user from a Klaviyo list.

Automatic Sync of WhatsApp Opt-In

Once Klaviyo is integrated, you can specify a property (default is "chatarmin_whatsapp") to automatically sync the WhatsApp opt-in status with your Klaviyo profiles—no need to do this manually in every flow.

Unified Email and WhatsApp Messaging

WhatsApp in combination with Klaviyo allows you to promote the same product to an audience even if they prefer different communication methods.

Using WhatsApp only for younger generations or social media users would be a mistake. The combination of WhatsApp, Klaviyo, and your shop system gives customers the freedom to choose how they receive marketing and updates.

Quick support inquiries can be handled via WhatsApp, while Klaviyo’s CRM data ensures controlled and segmented promotion.

More Ways to Segment Customers

Of course, customer segmentation isn’t limited to preferred touchpoints. Klaviyo also helps define customer groups based on:

Cold WhatsApp contacts from website buttons or widgets
Customer value
Preferred products or categories
Regular participants of on- and offline events

Example: Messaging the Same Customer via WhatsApp and Email

Klaviyo is a go-to tool for email marketing and automated confirmations. It also supports SMS and was an early adopter of direct smartphone communication.

Klaviyo has always reacted to abandoned carts with targeted emails to encourage checkout. Now, Chatarmin and WhatsApp integration can complement these emails with WhatsApp reminders.

Abandoned purchases become far less frequent with Klaviyo and WhatsApp. Whether you incentivize new customers to complete a purchase or remind returning ones about their favorite products—this combo works.

What Is Klaviyo Generally Used For?

The cloud-based Klaviyo platform was originally created to improve customer retention through email and SMS marketing.

Its first integrations were with platforms like Shopify and WooCommerce to simplify customer segmentation and send targeted newsletters to selected audiences.

Chatarmin has found in Klaviyo a partner that supports workflow and makes WhatsApp integration a valuable addition to your customer experience.
