# How to set filters
This section details the audience filtering functionality within your system, allowing you to target specific user segments for campaigns or actions.
### The filtering process involves two key steps:
1. **Attribute Selection:** Choose the user attribute you want to filter by. This could be any user data point you have collected, such as email address, location, or user type.
2. **Filter Operator:** Define the condition for filtering users based on the chosen attribute. Here's a breakdown of the available operators:
* **Is Set:** Filters users who have a value assigned to the chosen attribute.
* **Contains:** Filters users whose attribute value contains a specific text string. (e.g., email addresses containing "@gmail.com").
* **Not Contains:** Filters users whose attribute value does not contain a specific text string.
* **Less Than, Greater Than:** Filters users based on numerical comparisons with the chosen attribute value.
* **Starts With, Ends With:** Filters users based on whether their attribute value begins or ends with a specific text string.
* **Before, Is Date:** Filters users based on date comparisons with the chosen attribute value (e.g., signup date before a specific date).
### **Additional Notes:**
* The specific user attributes available for filtering will depend on the data collected by your system.
* You can combine multiple filters using logical operators (AND, OR) to create more granular audience segments.
* Previewing your filter criteria before applying it can help ensure you're targeting the desired audience.
### **Example:**
To target users who have signed up in the last month, you would select the "signup\_date" attribute and the "Before" operator, then specify the desired date range.
