Email revenue nearly doubled in 30 days
Sending identical campaigns to everyone was destroying engagement, open rates, and deliverability. Revenue was declining 27% period-over-period.
We rebuilt segmentation by customer type, rewrote key flows, and introduced a campaign calendar mixing story-driven and promotional sends.

Natural Skincare · DTC
+33% email revenue in 30 days
Email revenue declining 49% year-on-year. Poor segmentation and weak automation meant the list sat idle while paid ads did all the work.
We rebuilt segmentation by behaviour and buying stage, reworked flows per customer group, and introduced retention campaigns educating subscribers on products.

Home & Wellness · eCommerce
+22% email revenue in 30 days
Flows were live but underperforming. Campaigns were inconsistent and flow revenue was leaving money on the table every month.
We restructured the welcome series, tightened abandoned cart sequencing, and introduced a strategic campaign calendar. Total store revenue climbed 14% alongside.

"The audit alone was worth more
than we paid. They found
substantial monthly revenue that
was just sitting unrealised. We'd
been ignoring our list for two
years."
