1. Segmentation: Use behavior data to segment your email list. For example, you can create segments based on users who visited a specific product page or those who abandoned their shopping cart. 2. Personalization: Tailor your email content based on user behavior. If a user frequently visits your blog, send them updates on new blog posts. 3. Triggered Emails: Set up automated emails triggered by specific actions, such as a welcome email when someone signs up or a follow-up email after a purchase.
