With segment extensions, you can target audiences with more precision than segmentation alone. Segment extensions also allow you to:

use custom event properties
use purchase event properties
message engagement data logged over the past 2 years as criteria for a segment

Examples of segment extensions are:

A segment based on the time window an event was logged, such as users who have purchased a specific product at least twice in the past month.
A segment for users who have performed a custom event characterized by a specific event property.

Tip

There is a soft limit of 25 active segment extensions per app group at a particular time. This can be increased by contacting your Braze customer success manager to discuss your use case.

Using Segment Extensions in a Segment

Once you’ve added all your segmenting criteria, decide how often users should be evaluated for membership. By default, your segment extension will consist of users who meet the criteria at the time you initially save your segment extension. If you would prefer to reevaluate users for this segment on a daily basis, check the Regenerate Extensions Daily box, depicted in the image below next to the segment extension name.

Your Segment Extension can now be used in any segment, campaign, or Canvas. Open the settings for your desired segment or message targeting and add the filter Braze Segment Extensions. You’ll find a list of available segment extensions in the dropdown for this filter, as shown below:
