Learn how to add a tag to a list or segment in Klaviyo.
For lists and segments, you can either add tags when creating a list or segment, or you can add tags retroactively when they are already built in your account. This article will cover both methods.
Why use tags?
In Klaviyo, tags serve as labels that help you efficiently organize and manage items in Klaviyo (i.e., contact lists and segments). By attaching tags to lists and segments, you can quickly categorize and identify specific groups within your audience. For example, you can tag segments to distinguish between existing customers and prospects, or group lists that'll be used for specific promotions.
This streamlined organization makes it easier to filter, manage, and collaborate on different audience segments, enhancing your ability to target communications.
Add a tag when creating a list or segment
To add a tag when creating a list or a segment:
- Navigate to Audience > Lists & segments.
- Click Create.
- Select List or Segment. If Segment opens the segment builder directly, add your conditions and click Create segment, then follow Add a tag retroactively below to add its tags.
- Enter a Name for your list or segment.
- In the Tags dropdown, select the tags you want to add. To create a new tag, type its name and select Create new tag with that name.

- For a list, click Create list. For a segment, click Create segment to open the segment builder.
- For a segment, add the conditions that define who belongs in it, then click Create segment to save it.
