Retargeting involves sending reminder messages to customers through alternative channels if there is no response to the initial action, serving as a method to sustain engagement despite the lack of a desired outcome from the previous interaction. For instance, if a user adds a product to their cart on a mobile app but abandons the transaction, the brand can retarget the user by sending a cart abandonment reminder via a different channel such as an app push notification, email, SMS, or WhatsApp.

In the realm of retention marketing, retargeting focuses on leveraging various channels to ensure that users receive relevant information that can enhance their experience. Mastery of diverse communication channels is pivotal in retargeting efforts, with a keen understanding of the opportune moments to retarget customers being essential for boosting engagement and retention rates.

In the broader marketing context, retargeting entails displaying follow-up advertisements to website visitors and existing customers, encouraging them to revisit the platform. The overarching objective remains consistent across all scenarios: prompting users to complete actions that were previously left unfinished.
