Jinja2, which is usually referred to as Jinja, is a fast and secure templating language designed for Python. In Bloomreach Engagement, **it enables you to personalize your interaction with your customers**. One of its main tools are placeholder values, which then, during template's rendering, get replaced with values present in Bloomreach Engagement.



For example, when using the Jinja for the first name of your customer, the placeholder value - `{{ customer.firstname }}` - gets replaced with the first name of your customer, if their name is already stored in Bloomreach Engagement.

Jinja serves as a powerful addition to other personalization tools in Bloomreach Engagement, such as Weblayers, Experiments, and various Campaigns. Combined together, they can help you to make your customers feel that they personally matter to your business.
