If you're asking how to do retention marketing, you're already ahead of most brands. Why? Because everyone wants new customers, but few know how to keep the ones they have. Retention isn’t a single play - it’s a system. And the best brands build it from the inside out.
At Propel, we help brands engineer loyalty, not chase it. As a Platinum Customer.io Partner, we design full-stack retention systems across email, push, SMS, and beyond - so you can turn one-time users into lifetime customers.
This guide shows you how to do just that. Step-by-step. No fluff.

Retention marketing is the practice of engaging existing customers to increase repeat purchases, reduce churn, and grow lifetime value. In a world where CAC keeps rising, it's your most sustainable growth lever.
Acquisition brings people in. Retention makes sure they don’t leave. Smart brands invest in both - but retention scales better over time.
Retention campaigns are cheaper to run and easier to personalize. And they drive compounding gains - like higher CLV and lower CAC over time.
Headspace sends nudges based on meditation streaks. Amazon recommends exactly what you forgot to reorder. These are retention strategies in motion.
Customer retention strategies like these aren't random - they're deliberate, behavior-led flows.

You don’t need a massive team to win at retention - you need the right system. Here’s how to do retention marketing like a pro.
Start by understanding who you’re trying to retain. Use your CRM or CDP to segment:
Map their behaviors, lifecycle stage, and preferences. This sets up the rest.
Don’t just aim to “improve retention.” Define it.
Then track them by cohort and segment.
From Day 0 onboarding to Day 90 win-backs - map every moment where you can add value. Think:
These touchpoints become your flow triggers.
Retention doesn’t live in email alone. Choose channels based on user behavior:
Each has its place. The mix depends on your product and user base.
Retention marketing runs on automation. Tools like Customer.io and Braze let you:
You’re not sending newsletters. You’re designing experiences.
Retention is never set-it-and-forget-it. Audit flows monthly. Run holdouts. Check benchmarks.
Use retention marketing funnels to spot drop-off points - and fix them fast.
Retention isn’t vibes. Use a customer retention calculator to estimate how much money your flows are saving (or losing) you.
This ties your marketing efforts directly to revenue.
With these steps, you’ve got the blueprint. Now build.

Tactics turn strategy into outcomes. These are the plays the best brands use to keep customers engaged and coming back.
Abandoned cart emails. Post-purchase thank-yous. Product tips based on browsing history. Done right, email isn’t just a channel - it’s a memory machine.
Think beyond points. Offer surprise upgrades, early access, and real exclusivity. The best programs feel like a club - not a punch card.
Let high-value customers shop the drop first. Netflix launches new shows with sneak peeks to binge-watchers. FOMO + access = retention gold.

Track what matters:
Use Mixpanel, Amplitude, Customer.io dashboards. Bonus points for building retention reports by cohort and segment.

Retention isn’t just “send more emails.” Here’s what gets in the way - and how to fix it.
Not all churn is equal. Build reactivation flows for voluntary churn, and dunning flows for involuntary churn.
Use milestone emails, usage nudges, and feature highlights to keep interest high - even when users aren’t transacting.
Retention should tie back to revenue, LTV, and CAC payback. If it doesn’t - it’s not a strategy. See how MoEngage handles retention across lifecycle campaigns.
