The Klaviyo alternative built for modern teams
Klaviyo is great for e-commerce but ruinously expensive for SaaS. Sendbound gives you fair usage-based pricing, a developer-first API, and 94% lower cost at scale.
Built for a better email experience
Klaviyo is for Shopify, not SaaS
Klaviyo is incredibly powerful if you run a Shopify store. If you run a SaaS product, a mobile app, or a custom web platform, Klaviyo feels incredibly heavy and poorly suited to your data model.
Contact-based pricing is expensive
Like Mailchimp, Klaviyo charges you for the number of profiles in your database. Sendbound's usage-based pricing means you only pay for what you send, saving SaaS companies thousands.
Poor transactional support
Klaviyo is fundamentally a marketing tool. Sending critical, sub-second transactional emails like password resets through Klaviyo is slow and difficult to configure.
No React Email
Klaviyo locks you into their proprietary drag-and-drop editor. Sendbound lets developers build beautiful, version-controlled templates using React Email.
