About Klaviyo
Klaviyo is the default choice for online stores, and for good reason. It plugs straight into Shopify and other platforms, segments your audience on actual purchase behavior, and reports revenue per email rather than vanity metrics. SMS is built into the same flows. The price climbs steeply with your list, and outside e-commerce most of its power sits unused. If you run a store, start here.
“For online stores, nothing else comes close: the segmentation on purchase behavior and the revenue reporting are in a league of their own. Outside e-commerce, you are paying for power you will not use.”Editorial team, via MailShortlist
