Which Salesforce add-on is utilized for proactive customer engagement?

Gainsight is specifically designed to enhance customer engagement by providing tools and analytics that enable businesses to proactively manage customer relationships and improve satisfaction. It offers features like customer health scoring, automated outreach based on customer behavior, and lifecycle management, all aimed at keeping customers engaged and ensuring they maximize the value from the product or service.

In contrast, the other options serve different purposes. HubSpot is primarily a marketing and sales platform, focused on inbound marketing tools rather than specific engagement metrics for existing customers. Zoho offers a suite of business applications that may involve customer relationship management but does not specialize in proactive engagement like Gainsight. Salesforce Lightning is a user interface framework for building applications within the Salesforce ecosystem, which enhances the user experience but doesn't directly focus on proactive engagement strategies specifically. Thus, Gainsight stands out as the dedicated tool for proactively managing and enhancing customer interactions.
