How Automated Klaviyo Flows Generate 35% of Monthly Revenue

Email automation is one of the highest-ROI channels available to Shopify brands — but only when the flows are built with genuine intent. For one of our UK homeware clients, a full audit and rebuild of their Klaviyo setup turned a neglected channel into a revenue engine that now contributes 35% of monthly sales without any ongoing ad spend.

The Starting Point

When they came to us, the brand had a basic welcome series and a dormant abandoned cart flow. Email accounted for around 8% of revenue. The list had grown to 42,000 subscribers but engagement was poor — open rates below 18% and click rates under 1.5%. The flows were generic, unsegmented, and firing at the wrong cadence.

The Flows We Built

• Welcome series (5 emails over 10 days, brand story led)
• Abandoned cart sequence with dynamic product imagery
• Browse abandonment triggered at 30 minutes
• Post-purchase onboarding with care guides and cross-sells
• Win-back series for subscribers inactive for 90 days
• Review request timed to product delivery estimates

Segmentation Was the Real Unlock

Every flow was split by customer segment: first-time buyers, repeat purchasers, and high-LTV customers. Rather than sending the same abandoned cart email to everyone, high-LTV contacts received a personalised message from the account manager. First-timers got social proof and a soft incentive. The tailoring made an immediate difference.

Results After 90 Days

• Email revenue share: 8% → 35% of monthly total
• Average open rate: 18% → 41%
• Click-to-open rate: 1.5% → 6.8%
• Unsubscribe rate held below 0.2% throughout

“We knew email was underperforming but didn't realise by how much. The new flows paid for the project within six weeks.”

The key lesson: automation only works when it is built around the customer journey, not just the platform's default templates. Investing time in segmentation and copy before touching the flow builder is what separates high-performing programmes from the rest.
