Zeta Markup Language (ZML)
Zeta Markup Language (ZML) is based on the open-source template language Liquid created by Shopify. ZML is used in the Zeta Marketing Platform to perform personalization and dynamic operations within the content. ZML code can be categorized into objects, tags, and filters.
Objects
Objects tell ZML were to show content on a page. Objects and variable names are denoted by double curly braces: {{ and }}. This is how user properties can be populated within the content to perform basic personalization.

In this example, ZML is rendering the content of an object containing the user property called first_name, and that object contains the string, Ryan.
Tags
Tags are used to define logic within the content. They are denoted by curly braces and percent signs: {% and %}. This markup used in tags usually does not produce any visible text. Possible exceptions are noted below. This means that you can assign variables and create conditions and loops without showing any of the ZML in content.
