# Segment Samples
***
By clicking on the **three dots** and clicking "**Create sample"** you can create a specific sub-segment by creating a sample size. E.g. If 1000 users are in a segment and you create a sample of 100, you will create a subsegment with 100 randomized users of the previous segment. This can be useful to test campaigns on a smaller sample size.
