What’s included
A Klaviyo agency sets up your account, connects your store data and builds the flows, segments and campaigns that bring customers back. We cover the full program or only the parts you need, and everything is built in your own Klaviyo account.
01
We audit your Klaviyo account, then set up the structure, profile properties, metrics and naming the rest of the program depends on.
02
We connect Klaviyo to Shopify, BigCommerce, WooCommerce or a custom store so orders, products and browsing events arrive cleanly.
03
We build welcome, abandoned cart, browse abandonment, post-purchase, winback and back in stock flows, with branches for new and repeat buyers.
04
We build segments on purchase history and engagement, and set up signup forms that grow the list without getting in the way of shopping.
05
We plan a content calendar of email campaigns and run Klaviyo SMS alongside it, with consent capture and quiet hours set up correctly.
06
We authenticate your sending domain, keep the list clean with a sunset flow, and A/B test subject lines, content and send times.
How we run it
A Klaviyo engagement starts with an audit of your account, store data and existing flows. We fix the foundations, launch the highest-value flows, then add campaigns, SMS and testing.
Klaviyo is one part of our email marketing services. It works best with a store built through Shopify development, clean tracking from GA4 setup and analytics and on-site testing from conversion rate optimization. For an example of our ecommerce work, read the Spooky Costumes case study.

Questions
Start with welcome, abandoned cart, browse abandonment and post-purchase flows, because they reach shoppers at the moments they are most likely to buy. Once those run cleanly, add winback, back in stock and replenishment flows. We build each flow with filters so first-time buyers and repeat customers get different messages, and we test timing before adding more steps.
Yes. We start with an audit of your flows, segments, campaigns, signup forms and deliverability, keep what works and rebuild the rest in phases. Most takeovers begin with data and sending domain fixes, then the highest-value flows, so the program keeps sending while we improve it. You keep full ownership of the account and everything we build in it.
Yes. We set up Klaviyo SMS with compliant consent capture, quiet hours and separate flows for subscribers who opt in to texts. SMS suits time-sensitive messages like shipping updates, launches and back in stock alerts, so we plan it together with email and avoid sending the same message on both channels.
We measure flow revenue, campaign revenue, revenue per recipient, list growth and deliverability, checked against your store and GA4 data. Reports come monthly alongside your other channels, so email and SMS are judged on revenue rather than on open rates, which Apple Mail Privacy Protection now inflates.
