Overview

What changed

Challenge

Growth that email could not keep up with

Brand 3's acquisition was working almost too well. The store grew 346% in a single month, and the retention side was not built to absorb that kind of intake.

New customers were arriving faster than the existing flows could convert them. Email's share of revenue was falling even as email revenue itself rose, because the denominator was growing faster. This is the standard hypergrowth trap.

There was also a real deliverability risk. Scaling send volume that quickly, without segmentation, is how brands land in spam.

Strategy

What we did

1.Mapped where new customers were leaking

We traced exactly where the surge of first-time buyers dropped out of the funnel, and which automated journeys were missing entirely.

2.Rebuilt flows for volume

The flow suite was rebuilt to absorb incoming customers at scale and convert them while intent was still high.

  • Flows took 60.2% of email revenue

3.Scaled campaigns with the list

The campaign calendar ramped in step with list growth: more buyers, more sends, the same quality bar on each one.

4.Protected deliverability under load

A managed volume ramp kept inbox placement stable through the growth spike, which is the point where most retention setups quietly break.
