One of the largest companies in fitness: 20+ years in market, one of the biggest organic audiences in the industry, and an email channel badly under-built for the size of it. We built the full infrastructure, launched SMS from scratch, and within 60 days they saw a 51x ROI, with the previous setup beaten by 47% and revenue up 15%.

Intake memo · File No. 004

Athlean-X is one of the largest companies in the fitness and supplements space: over 20 years in market with one of the biggest organic audiences in the industry, and an email channel badly under-built for the size of it. What existed was a pre-purchase-only setup wired up by a generalist years ago. We built out the full infrastructure and launched their SMS channel from scratch, with a paid-ads push on the horizon making the timing right.

// The brief

What they hired us to do

01
Goal 01

Extract more from organic

Turn a massive content audience into more owned-channel revenue without burning it out.

02
Goal 02

Launch SMS

Stand the channel up from zero, done right from day one.

03
Goal 03

Paid-ready retention

Build the lifecycle machine so the upcoming paid traffic converts and compounds instead of leaking.

// The autopsy

Where the revenue hid — THE STARTING POINT —

A pre-purchase-only setup from years ago, on an audience this size, meant specialist-sized money sitting unclaimed: replenishment reminders, subscriber upsells, and pre-purchase nurture optimizations nobody had reason to go looking for.

What we shipped

01
Stop 02 · Strategy

Built around the audience

A strategy matched to a giant organic engine: extract more from the traffic video and blog already bring in, and get the list ready for paid.

02
Stop 03 · Core flows

The specialist layer

Replenishment reminders, subscriber upsells, and optimized pre-purchase nurture flows. The plays a generalist setup never gets around to.

03
Stop 01 · SMS

Launched SMS from zero

Stood the channel up properly: compliant, consented, and contributing revenue from launch.

04
Stop 04 · Campaigns

Daily segmented sends

A daily campaign cadence across segments, bringing in substantial revenue every single day without fatiguing the list.
