Klaviyo lifecycle for Kidsplaza.vn.
3 years, 12 flows, +38% email revenue.

A top-3 Vietnamese kids retailer hired LUMA-E to own their Klaviyo end-to-end. We architected the flows, ran the experiment cadence, built the dashboards their team actually opens.

01 · The problem

Email was a $0.30 line item, not a channel.

Kidsplaza was running 1 welcome flow + occasional batch campaigns. List was 240k strong but engagement was dropping every quarter. Email-attributed revenue sat at <6% of total. The internal team owned the tool but didn't have the bandwidth to architect, segment, or experiment.

The brief was simple: own Klaviyo. Make it actually move revenue. Don't break what's already working.

02 · What we shipped

12 flows, RFM segmentation, a dashboard.

We rebuilt the lifecycle from the ground up in the first 90 days, then ran monthly experiments and quarterly architecture reviews from there.

  • Welcome series — 5 emails, 14-day arc, $7 first-purchase incentive
  • Abandoned cart — 3-touch with SMS escalation on touch 2
  • Browse abandon — gated to high-intent categories
  • Post-purchase — 4-touch with replenishment ping at day 30
  • Win-back — 3 segments × 3 offer tiers
  • VIP — top 5% RFM with early access drops
  • RFM segmentation rebuilt across 9 segments
  • Looker Studio retention dashboard, refreshed weekly
03 · Results

+38% email revenue in 90 days. Held for 3 years.

The lift wasn't a campaign spike — it was an architecture change that compounded. We continued the retainer for the experiment cadence and the quarterly architecture reviews. Three years in, the model still ships.

"We had Klaviyo for two years before LUMA-E. They didn't add tools. They architected what we already had into something that ships revenue every month. Three years later they're still the team we trust with lifecycle."
