Email Flows Drive +425% Revenue Surge

The Challenge

Greenpak was over-reliant on paid search for repeat purchases. Existing customers who should have been returning organically or via email were being re-acquired through paid channels — an expensive way to retain already-converted customers.

Our Approach

We built a full Klaviyo lifecycle automation system to capture, nurture, and reactivate customers without paid spend.

What we did:

• Welcome flows introducing new customers to the product range
• Post-purchase sequences driving repeat orders at optimal intervals
• Replenishment campaigns timed to product lifecycle data
• Winback flows targeting lapsed customers before they churned
• Shopify tag segmentation for personalised messaging
• A/B testing on subject lines and send timing

The Results

• +425% increase in Klaviyo-generated revenue in Q1 2025
• Reduced dependence on paid search for repeat customers
• Lifted repeat order rates and increased average customer value
• Email became a reliable, owned revenue channel instead of an afterthought
