How we ran it

01

The challenge

HDM needed a reliably full sales calendar — a steady flow of qualified calls with Ecommerce decision-makers — without pulling their team into day-to-day prospecting.

02

Who we targeted

We built verified lists of the Ecom operators who feel the pain HDM solves — leaving revenue on the table in their email channel.

What we ran

A cold email engine built for scale — 494,307 sends, roughly 1.5 touches across 324,092 brands — positioning HDM on the outcome Ecom teams care about: retention revenue and ROI from email.

Warmed infrastructure kept the bounce rate at a clean 1.52% with zero unsubscribes, and fast human reply handling turned 8,968 replies and 842 interested brands into booked calls.

The outcome
