Case study · Diamond ProTech
Two welcome flows. Same 90 days. 12x.
Diamond ProTech makes pro-grade ceramic coatings for certified installers and serious detailers. Instead of guessing whether a new welcome flow would beat the old one, we A/B tested it: both flows live, head to head, with real orders keeping score.
The setup
A head-to-head, on purpose.
The brand
Diamond ProTech: ceramic coatings and detailing products at diamondprotech.com, selling to both certified pro installers and enthusiasts, on Klaviyo.
The work
A rebuilt welcome flow, launched as a live A/B test against the 2022 original. Same store, same window, two very different sequences. The numbers picked a winner.
The numbers · same 90 days
The rebuild ran away with it.
All numbers tracked in Klaviyo across the same recent 90-day window in 2026: the new flow vs the 2022 original, both live the entire time.
How
What actually moved it.
Built to sell, not just say hi
The old flow greeted people. The new one converts them: 2.4% of everyone who receives it places an order, forty times the old rate, on far fewer sends.
Bigger baskets
It's not just more orders. It's better ones. Average order size doubled, because the sequence sells the system, not a single bottle.
Tested, not assumed
Seasonality can flatter any before/after, which is exactly why this was run as an A/B test. Both flows shared the same 90 days and the same market, and the rebuild still won 12x.
