Customers love us

Preferred by product-led companies

Up until now, we’ve sold primarily through e-commerce channels. Now, we’re going much more omnichannel and want to integrate our product much more closely with our email marketing, we made the switch from Klaviyo to Customer.io.

Daan Goossens

VP of Growth

We know how important data is. Not only that, but to own your own data. That’s why we chose Customer.io.
