Introducing WhatsApp in Klaviyo

B2C brands face a simple but pressing challenge: how do you meet customers where they already are?

With more channels than ever and global audiences demanding instant, personalized communication, the ability to connect in real time-on the right channel, with the right message-has never been more critical.

For much of the world, that channel is WhatsApp.

With more than 3 billion active users and dominance in regions like the UK, France, Germany, Spain, Italy, Singapore, and Australia, WhatsApp isn't just another app. It's the world's most widely used messaging platform, and it's where your customers expect to hear from you.

Today, we're excited to announce that WhatsApp is now available in Klaviyo.

Why WhatsApp matters

Across Europe, Asia Pacific, and Latin America, WhatsApp is already the default channel for personal and business communication. A recent Meta study found that 74% of online adults want to chat with businesses just like they do with friends and family-so for markets like the UK and Germany, ignoring WhatsApp means ignoring the channel where most of your customers spend their time.

Even for US-based brands, WhatsApp is a critical unlock. Many American companies are selling in international markets where WhatsApp adoption is near universal. Reaching those customers via email or text messaging alone is only one piece of the puzzle. The most effective marketing strategy orchestrates all 3 channels to work together based on what a customer actually needs in each moment.

And now, with Klaviyo, marketers can add WhatsApp seamlessly into their omnichannel strategy.

What you can do with WhatsApp in Klaviyo

By bringing WhatsApp into the Klaviyo platform, brands can:

• Deepen relationships with two-way conversations. Engage customers in real time with automated and live chat, catalogs, carousels, quick replies, and rich media.
• Reach customers where they are, at scale. Orchestrate campaigns and flows with email, text messaging, push notifications, and WhatsApp from a single canvas, powered by Klaviyo Data Platform.
• Deliver personalization and measure impact. Personalize WhatsApp messages with Klaviyo segmentation and predictive analytics. Then, track performance alongside every other channel for true ROI clarity.
• Connect marketing and service. Tie WhatsApp into service moments like order updates, returns, or loyalty rewards with Customer Hub and AI agent integrations (coming soon). Create a seamless customer experience across every touchpoint.

What makes Klaviyo's WhatsApp offering different

There's no shortage of WhatsApp plug-ins on the market. But most are limited to basic broadcasts or siloed conversations. They can't tie WhatsApp data into the rest of your marketing efforts, they don't connect to service workflows, and they can't deliver AI-driven personalization.

With Klaviyo, WhatsApp is not "just another channel." It is fully integrated into your B2C CRM-powered by real-time profiles, AI-driven orchestration, and full-funnel analytics. That means:

• One profile, one source of truth, across every channel
• AI that routes messages to the best channel for each customer
• Unified analytics that show the impact of WhatsApp alongside email, SMS, and push

Our position is simple: a WhatsApp solution that sells and supports-at scale, powered by your data, all in one platform.

The future of B2C growth

For shoppers, WhatsApp means rich, conversational experiences on the channels they already use daily. For brands, it means higher engagement, stronger conversions, and expanded global reach.

And for marketers everywhere, it means finally being able to run omnichannel campaigns and flows that truly span borders, all from one platform, one data foundation, and one AI engine that adapts in real time.

With WhatsApp now part of Klaviyo, the world's most popular messaging app becomes a core channel in the world's only B2C CRM.
