How a DTC brand pushed email to 42% of total revenue.

Nearly half of every month's revenue now comes from the retention channel we run — without a single extra dollar of ad spend.

Quick Summary

The turnaround, at a glance.

Brand Overview

Every sale depended on ad platforms.

Before working with us, Cloud Nine's revenue rose and fell with ad performance. Email existed, but automation was shallow, sends were inconsistent, and the channel produced only a small slice of monthly revenue.

Their goals were clear:

The Receipts

Straight from the Klaviyo account.

Klaviyo dashboard: $33,284.09 attributed revenue, 42.27% of total, up 92% vs previous period
April 2025 — $33.3K attributed (42.27% of total revenue), campaigns and flows both pulling their weight
Our Approach

What we actually did.

1.Full Account Audit

The audit exposed how little of the brand's revenue email was carrying — and exactly which buyer moments had no follow-up at all.

2.Complete Flow Suite

Welcome, Abandoned Cart, Post-Purchase, and Win-Back flows built end-to-end, with offers shaped by customer research rather than guesswork.

  • Flows now contribute 45.2% of email revenue on autopilot

3.Weekly Campaign Calendar

A consistent weekly rhythm of brand-matched campaigns — product, educational, and seasonal angles the list responds to.

  • Campaigns carry 54.8% of email revenue

4.Testing & Optimization

Offer and subject-line testing raised attributed revenue 92% — and pushed email's share of total revenue to 42.27%, month over month.

Results

A channel the brand fully owns.

Email now accounts for 42.27% of total revenue — $33.3K in the measured month, up 92% against the previous period. The brand is no longer hostage to ad platform swings: nearly half of revenue arrives through a channel it owns outright.
