Our retention strategies are designed to enhance audience expansion, recover lost revenues from abandonment, and reactivate disengaged customers across various platforms.

In this case, you can't initiate an abandoned cart recovery flow because Jane's mobile access is not identifiable to you. Such instances of unidentified abandoners could account for as much as ten times the potential revenue that has now slipped through the cracks. With Retention.com’s Reclaim solution, you can tap into our top-tier Identity Resolution technology, which can boost your SMS and Email revenue from Browse, Product, and Cart Abandonment flows by as much as 10 times. The onboarding process is straightforward and quick, allowing you to implement the system within hours rather than stretching it over months.
