How Patio Black Spot Removal made email 57% of all revenue in eight months
Patio Black Spot Removal are the UK specialists in treating black spot on natural stone permanently. We ran the full Klaviyo retention programme with them: campaigns, flows and audience growth.
A single-digit sideline
Email was a single-digit sideline of what the business earned. Eight months later it was 57% of it. What changed was what landed in the inbox, and how often.
Campaigns for the volume, flows for the value
1.3M emails went out across the period. Campaigns brought the volume, flows brought the value: campaign sends earned £0.17 per recipient at scale, and the automated flows earned £2.99 per recipient, 17x more, converting 3.86% of everyone they reached.
Campaigns
Campaigns carried the volume across the 1.3M emails delivered in the period, and earned £215.1K, up 306% year on year.
Klaviyo flow build
The Welcome Flow led with £79.6K, earning £6.98 for every recipient it reached. Put the core flow metrics against Klaviyo's peer benchmarks for Housewares, Home and Garden ecommerce, and every one of them lands in the top tier.
Audience growth
53.5K active profiles by the end of the period, up 25% year on year and up 18% on the previous period.
What the eight months did
Between November 2025 and June 2026, the Klaviyo programme earned £384,190 in email-attributed revenue, 57% of the £677.6K the business took overall. That's a 418% increase on the previous period, and more than triple the same months last year.
Email's share of total business revenue grew more than sixfold in one period. A single-digit sideline became 57p of every £1 the business earns.
A list that keeps getting warmer
Behind the revenue, the list itself grew and warmed up. More active profiles, and tens of thousands of net new engaged openers added over the period.
