Quick Summary

The turnaround, at a glance.

Brand Overview

A growing store where email under-delivered.

Tuned in Tokyo was growing well — total revenue up 465% across the half-year — but email lagged behind the store's momentum. Under 10% of revenue came from the channel, flows were thin, and each new month of growth widened the gap between what email earned and what it should have.

Their goals were clear:

Our Approach

What we actually did.

1.Full Account Audit

The audit showed a store growing far faster than its email channel — under 10% attribution with most buyer journeys ending after one purchase.

2.Flow-First Rebuild

We rebuilt the automation layer to do the heavy lifting: welcome, abandonment, post-purchase, and win-back journeys tuned to the brand's buying cycle.

  • Flows grew +443% to $93.7K — 79.9% of all email revenue

3.Campaign Layer on Top

A steady campaign rhythm added reach without list burnout — campaigns up 385.7% while revenue per recipient climbed to $0.46.

4.Compounding Optimization

Month-over-month testing kept the ramp steep: April's 9.62% attribution became May's 21.87% — email's share of the store doubled in 30 days.

Results

The channel caught up — then kept climbing.

In 30 days, email went from 9.62% to 21.87% of total store revenue — $47K in the month of May alone (+142%). Across the half-year, attributed revenue reached $117.3K, up 430.4%, with four-fifths of it arriving through automated flows.
