Getting smarter all the time

Through Klaviyo’s commitment to data science and machine-based learning, we’re reducing the burden of finding insights.

Purposeful personalization

Successful emails deliver the most relevant content to a customer at the right time—which is why our segmentation tool is so incredibly powerful. You can easily engage with your customers based on how they interact with your brand, automatically sending everything from abandoned cart emails to product recommendations based on past purchases.

Eliminating technology sprawl

We integrate natively with customer data sources and build the technology to house data at scale, create experiences across channels, and measure the results. You shouldn’t need to stitch technology together or pay more than once.
