How Does Collaborative Filtering Work in Email Marketing?
Collaborative filtering works by analyzing data such as user interactions, click rates, and purchase histories. There are two main types of collaborative filtering:
User-based Collaborative Filtering: This method finds users with similar behavior patterns and preferences, then recommends content that those similar users have engaged with. Item-based Collaborative Filtering: This method focuses on finding relationships between items (such as emails or products) and recommends items that are frequently interacted with by the same users.
