Retention or acquisition? Most marketers treat it like a binary choice. But if you’re choosing sides without knowing your CAC, LTV, and churn rate - you’re probably choosing wrong.
Retention is what keeps the lights on. Acquisition is what makes people notice your building in the first place. At Propel, we’ve helped brands scale both - efficiently, profitably, and in sync. And as a Platinum Customer.io Partner, we know where each lever pays off (and where it doesn’t).
This post breaks down what makes each strategy powerful, when to use them, and how to strike the right mix for your growth model.

Not sure if you're leaking value post-purchase or overspending upfront? The difference starts with your metrics - and our customer retention calculator can help you crunch them right now.
Retention marketing kicks in after the first purchase - it’s about turning customers into repeat buyers. Acquisition gets them in the door. One builds familiarity. The other builds first impressions.
Acquisition tactics include paid ads, SEO, influencer marketing, and referral incentives. It’s the art of turning cold leads into new customers.
Retention focuses on building trust and loyalty post-purchase using emails, push notifications, loyalty programs, and behavior-based flows.
Both matter. But if you can’t retain, you’ll always overspend to grow.

Most brands default to acquisition because it’s loud, measurable, and VC-friendly. But retention? That’s the compound interest engine everyone ignores - until CAC gets too high.
Spending $200 to acquire a customer who churns in 30 days? That's a churn treadmill, not a strategy.
Retention alone won’t grow your top line if your pipeline’s dry. Especially if you’ve tapped your best-performing segments.
We’ve seen DTC brands spend 80% of budget on ads - with zero loyalty flows. And SaaS startups ignore activation drop-off until churn kills their MRR.
✅ Here’s how we fixed customer retention in ecommerce.

There’s no universal rule - but your metrics will tell you which deserves more attention.
Focus: Retention
You’re bleeding users faster than you're acquiring. Fix the leaky bucket first.
Focus: Retention
At that LTV:CAC ratio, acquisition isn’t scaling. Retention lifts repeat revenue and ROAS.
Focus: Acquisition for new SKUs, retention for existing.
✅ If unsure, talk to a customer retention specialist who’s done this before.

Yes. Acquisition is front-loaded and expensive. Retention is long-term and margin-friendly.
Acquisition can scale fast with budget. Retention requires personalization, systems, and iteration.
Possible in early-stage teams. But as complexity grows, it’s best split into distinct roles.
Retention specialists inform post-acquisition messaging, while acquisition teams generate qualified pipeline. The sync drives full-funnel growth.
