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.
- Klaviyo programme audit - identifying the gaps, underperforming flows and deliverability issues holding your programme back
- Flow architecture and build - welcome series, abandoned cart, browse abandonment, post-purchase, winback and VIP flows
- SMS strategy and implementation - building Klaviyo SMS alongside email for time-sensitive, high-intent moments
- Segmentation strategy - moving from list-wide sends to highly targeted communications based on behaviour, purchase history and predictive analytics
- Deliverability management - list hygiene, sender reputation monitoring and suppression strategy
- A/B testing framework - systematic subject line, content and send-time testing that compounds programme performance over time
- Revenue attribution and reporting - understanding the true commercial contribution of your email and SMS programme
A well-architected Klaviyo programme is one of the most defensible assets in e-commerce. We help you build it properly.
