The focus is on clear email sequences, re-engagement messages, winback emails, and steady touchpoints through email and SMS. Each step aims to keep customers active, lower churn, and encourage another purchase. Nothing complicated, just practical communication that supports long-term loyalty.

Optimize & Scale
After the flows are running, we keep adjusting them. Some segments need tighter filters, others need lighter ones. We test small ideas, try new retention angles, and look for steady lifts in repeat orders and customer value. The changes may seem minor, but they add up over time and help the store grow in a stable way.
