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.

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

Daniel Sand

CEO

We use all channels in our campaigns, when it makes sense to do so. Last month we sent over 11M emails, over 5M push notifications, almost 1M in-app messages, and almost 100,000 SMS messages from Customer.io.
