Klaviyo Partner agency, specialised in
Klaviyo ShopifyYour CPA keeps rising. Ads aren’t the problem. Retention is.
Every year it costs more to win a customer through ads. Most stores pay for that customer once and then never follow up properly. No welcome series, no post-purchase journey, no reason to come back.
Without a retention system
- You pay for every order through ads
- First-time buyers never hear from you again
- A rising CPA eats your margin
With WinningFlows
- Customers you already paid for buy again
- Flows sell every day without extra ad spend
- Email becomes a revenue channel you own
Spending more on ads won’t fix that. Earning more from the customers you already paid for will. That’s what email does when the system behind it is built right.

Frequently asked questions
How fast will I see results?
Flows start working the moment they go live. Revenue usually builds over the first weeks as more customers move through them and we optimise on real data.
Do I own everything you build?
Yes. Everything is built in your own Klaviyo account. Flows, templates and data stay yours.
How much of my time does it take?
Very little. You give us access to Klaviyo and Shopify and approve the direction. We handle strategy, copy, design, build and optimisation.
Which platforms do you work with?
We specialise in Shopify stores using Klaviyo. Not on Klaviyo yet? We set up your account for you.
What results can I expect?
Our clients typically get 15% to 30% of their total revenue from email. It varies per store, depending on your traffic, list and offer.
