About The Mail Cohort
We make the discipline of retention legible to operators.
The Mail Cohort began in 2017as a single retention practitioner's notebook, a place to write down what actually moved the needle for ecommerce brands, stripped of the jargon and the vendor hype.
Today we're a small studio that does two things: we run hands-on advisory engagements, and we write Mailbites for 24,000+ operators. The teaching and the consulting feed each other, the newsletter sharpens the client work, and the client work keeps the newsletter honest.
Our philosophy
Four beliefs that shape the work
We're opinionated about how retention should be practiced. These are the principles we won't compromise on.
Teach, don't gatekeep
We publish the frameworks we use with clients. An informed operator is a better partner, and the work speaks for itself.
Margin over vanity
We optimize for contribution margin and payback, not open rates and follower counts. The numbers that pay salaries are the ones we move.
Systems, not band-aids
We build programs your team can run without us. Dependency is a failure mode, not a business model.
Evidence over opinion
Every recommendation traces back to your cohort data or our own analysis. We'd rather be right than confident.
Our approach
How an engagement actually works
No generic playbooks. We start in your data and end with a system your team owns.
Diagnose with data
We start in your numbers, cohorts, margins, flows, not a generic playbook. The diagnosis determines the work.
Prioritize by leverage
We find the few interventions that move the business most, and we sequence them by impact and effort.
Build the machine
We ship the flows, segments, and systems inside your stack, not slides describing what you should do.
Hand off the keys
We document everything and train your team, so the program compounds long after the engagement ends.
