Retention is nuanced. It’s about messages sent at the right moment, to the right segments, through intelligent systems. Most agencies treat it like an add-on.

A retention marketing agency helps brands keep customers engaged and coming back by using personalized email, SMS, push campaigns, loyalty programs, and behavior-driven messaging.
Propel focuses solely on retention-first growth for DTC and subscription brands, combining AI agents and human strategy for precision lifecycle marketing.
No. While some support ecommerce, only a few (like Propel) specialize in subscription-based and direct-to-consumer models where retention drives revenue.
Most in-house teams manage top-of-funnel campaigns. Retention requires behavioral data, segmentation models, testing, and automation—agencies like Propel help you build that fast.
Look at their case studies, industries served, and whether they’ve helped similar brands. If you’re DTC or subscription-first—Propel should be your first call.
