Key Features

Powerful Segmentation

If you can think it, Klaviyo can segment it in seconds, without any limitations on parameters. (Want to reach women named Riley who bought red pants last Wednesday? You can.)

Pre-built & Custom Reports

Get clear answers to key questions— message performance, revenue growth, email vs. SMS. Examine the business from every angle: metrics deep dives, campaigns, flows, and products.
