# Retention

> Retention helps ecommerce and publisher brands identify anonymous website visitors, grow first-party data, and re-engage shoppers across email, SMS, and paid media.

Retention is an identity resolution and audience growth platform. It captures behavioral signals from site visitors, matches them to deterministic identity and contact data, and activates that data through integrations with email service providers, SMS platforms, advertising networks, and customer data platforms.
