What we do
Five disciplines, one compounding system
We work across the full retention stack. Most engagements start in one area and expand as the program proves itself.
We rebuild your email program around the messages that actually move revenue, from welcome and post-purchase flows to a campaign calendar your subscribers look forward to.
Outcomes
- 30–45% of revenue attributed to email & SMS
- Welcome and post-purchase flows rebuilt from first principles
- A campaign system your team can run without us

Audit
Teardown of every flow, campaign, and metric against benchmark.

A flow map and calendar designed for your margin and cycle.
- 3

We ship the flows and templates inside your ESP.
- 4
Hand off

Case studies
The work, told as stories
Not testimonials, the actual problem, the actual intervention, and the numbers that moved.
Bending the retention curve on a one-and-done category
Case study by Anil Kumar
Challenge
North Supply had strong acquisition but a brutal retention cliff, 78% of customers never placed a second order. Paid spend was scaling revenue while the customer base quietly leaked out the bottom.
Solution
We rebuilt their post-purchase program around product affinity and consumption timing, introduced a replenishment engine for their consumable lines, and re-sequenced the welcome flow to lead with education instead of a discount.
Result
Second-purchase rate climbed from 22% to 37% over two quarters, and email-attributed revenue nearly doubled, without increasing acquisition spend.
“The Mail Cohort didn't hand us a deck. They rebuilt the actual machine, then taught our team to run it. The retention curve is a different shape now.”
