Klaviyo

Klaviyo is an email and SMS marketing platform for online retailers that syncs orders and customers from the store and runs automated abandoned-cart, welcome and post-purchase flows.

Klaviyo is the usual marketing tool of direct-to-consumer brands, above all on Shopify, so the 424,968 websites are nearly all shops: fashion, beauty, supplements, home goods, food and pet brands, mostly in the United States, the United Kingdom, Australia and Canada. Paid once a store has a real contact list, it marks an active shop with revenue and someone managing retention.

The list is bought by vendors of e-commerce apps (reviews, loyalty, subscriptions, SMS, customer support, returns), fulfilment and shipping companies, performance-marketing and email agencies, wholesale and sourcing services, and lenders or payment providers that target growing brands. A store that newly adds Klaviyo is scaling its marketing beyond the basics; a store that drops it has either changed platforms, moved to a competing tool or stopped trading, each of which is a different kind of lead.
