How to Integrate Klaviyo with Other Marketing Channels for Holistic Campaigns

So, you’re a marketer looking to deliver personalized experiences that actually convert, not just across email, but across every channel your customers touch.

But here’s the reality: 

• Your email campaigns live in one silo.
• Your social ads operate in another. 
• And your SMS, push notifications, and website pop-ups? They’re rarely in sync.

The result? Fragmented messaging. Missed opportunities. And a customer experience that feels anything but seamless.
