# Segment Types

### Static List

These are nothing but a list of CSV customers that you can upload. The static segment doesn't change once it is created, users in these segments are fixed. Learn more about the Static Segment.

### Real-time Segments

Dynamic segments keep themselves updated based on the rules mentioned for the segments. Dynamic segments can be defined using three rules:

* **Segment By User Attributes/Properties:**
  * With a User Property filter, you can group customers based on their properties like City, Total Orders, Last Order At, etc.

* **Segment By Performed Activity:**
  * With the 'Performed Event' filter, you can group customers based on certain activities they might have performed.
  * For example, you can segment customers by those who have performed the 'Purchased' activity in the last 60 days.

* **Segment By Not Performed Activity:**
  * With the 'Not Performed Event' filter, you can group customers based on certain activities they might have not performed.
  * For example, you can segment customers by those who have not performed the 'Purchased' activity in the last 60 days.
