Personalization is crucial in creating an engaging user experience that turns first-time visitors into loyal customers. Conversational applications are effective tools for personalizing a user's interaction with a product, enabling brands to craft specific and contextual responses based on users' actions and preferences. To create conversational messaging across the user lifecycle, it is essential to focus on three main stages: activation, retention, and re-engagement. Personalized messages can be delivered through various channels such as emails, product tours, push notifications, and chatbots. Successful companies use personalization strategies to improve user engagement and increase customer lifetime value.
