Personalization
Personalization tailors email content and timing to individuals using consented data so messages feel relevant.
Definition & Examples
What is Email Personalization?
Personalization is the practice of tailoring your marketing messages to each individual recipient based on their unique characteristics, behaviors, and preferences. It goes beyond simply inserting a first name in a subject line; true personalization leverages data such as past purchases, browsing behavior, demographics, and stated preferences to deliver content and offers that feel genuinely relevant to each person receiving them.
Modern email personalization combines data analysis, list segmentation, and dynamic content delivery to create individualized experiences that resonate with subscribers on a personal level.
