What is retention?

The ability to keep customers or users over time.

In plain English

Retention is the other side of churn. It measures how many customers stay, and it determines whether marketing effort accumulates or simply replaces what leaked out.

It is consistently underfunded relative to acquisition, largely because new customers feel like progress and existing ones feel like a given. The arithmetic says otherwise.

What to know

Cheaper than acquisition
You have already paid to acquire these people and they already trust you. Selling again costs a fraction.
Onboarding sets it
Whether a customer gets value quickly at the start predicts how long they stay better than almost anything else.
Communication is retention work
Customers who never hear from you drift. Regular, useful contact is why email remains so effective for this.
Measure cohorts, not averages
Whether customers who joined this quarter stay longer than last quarter tells you if you are improving.

Why it matters

Improving retention lifts lifetime value, which raises what you can afford to spend acquiring customers, which opens channels that were previously uneconomic. It is the change that makes every other part of the marketing model work better.

Common mistakes

×Directing nearly all budget at acquisition.
×Neglecting onboarding, then blaming the product for cancellations.
×Only contacting customers when selling something.
×Measuring retention as a single blended average.
