Klaviyo Email and SMS Marketing

Klaviyo Partner Agency

Klaviyo Email
& SMS

Retention-first email and SMS programmes that turn your subscriber list into your most profitable channel.

Sardio is a Klaviyo partner agency building and managing email and SMS programmes that drive measurable retention and revenue for e-commerce brands. Most brands underuse Klaviyo significantly - running a welcome series and an abandoned cart flow and calling it done. We build the full programme that turns email and SMS into the highest-ROAS channel in your stack.

A well-architected Klaviyo programme is one of the most defensible assets in e-commerce. We help you build it properly.
