# Retention Control > Retention marketing for Shopify and DTC brands. We build the owned-channel > systems - email, SMS, lifecycle automation and loyalty - that turn one-time > buyers into repeat customers. Works across Klaviyo, Omnisend, Brevo > and Attentive. Working with 150+ Shopify store owners across the US, UK, > Ireland and Europe. Retention marketing is not a channel, it is an objective: increasing how often existing customers buy and how long they keep buying, measured in repeat purchase rate and lifetime value rather than open rates. Engagements start with a free 60-minute audit of the current setup. ## Start here - [Retention Marketing](https://retentioncontrol.com/retention-marketing/): The pillar guide - what retention marketing covers, the six service lines (including AI voice agents), where each flow sits in the lifecycle, and which platform suits which catalogue. - [What Are Automated Flows for DTC Brands?](https://retentioncontrol.com/what-are-automated-flows-for-dtc-brands/): All ten flows explained - the eight that run all year plus the two seasonal ones (BFCM, Christmas).
