Take a random sample of a list or segment
You need permission to edit lists and segments, and your account must be below its list limit to create a sample.
- Navigate to the Audience > Lists & segments tab of your account.
- Click a list or segment.
- In the upper right-hand corner of your screen, click either:
- Manage segment > Create random sample (for a segment).
or - Manage list > Create random sample (for a list).
- Manage segment > Create random sample (for a segment).

- Enter a name for the new list in the List name field.
- Input how many people you would like to be included in this sample in the Sample size field.

- Click Create list.
Klaviyo opens the new list and adds the randomly selected profiles. The original list or segment keeps its members. The sample is a static list, so it does not automatically update when the original list or segment changes.
The new list uses your account's default opt-in setting. If you sample an SMS list or SMS subscriber segment, or a list or segment with "sms" in its name, the new list uses double opt-in.
