Klaviyo Retention Marketing Services in USA

Klaviyo is one of the most powerful retention marketing platforms available for eCommerce brands but most businesses only use a fraction of its potential.
At RetentionControl, we help USA eCommerce and DTC brands unlock the full power of Klaviyo to turn one-time buyers into repeat customers, and repeat customers into long-term revenue.

What is Klaviyo Retention Marketing?

Klaviyo retention marketing is the use of data-driven email and SMS automation inside Klaviyo to increase customer lifetime value (LTV).

Unlike basic email marketing, Klaviyo allows you to:

Track real-time customer behaviour

Segment audiences dynamically

Trigger personalised flows based on actions

This enables you to deliver the right message, to the right customer, at the right time.
