Using Cohorts

The Cohorts you create can be used for targeting across various Hackle features.

Setting Up Targeting

This section covers how to target a Cohort in an A/B Test.

The method for setting up Cohort targeting in Feature Flags and Remote Config is the same.

Setting Up a Cohort Filter

Supported Operators

The Cohort filter currently supports two operators: = and ≠.

Select the Target Cohort from the List

The User Identifier Basis of the experiment and the User Identifier of the Cohort must be the same.

If the experiment's User Identifier Basis is deviceId, the Cohort's User Identifier must also be deviceId.

Experiment User Identifier - deviceId

Targeting - Cohort list

Therefore, only Cohorts with the same User Identifier as the experiment are shown in the targeting list.

The active user Cohort has deviceId.

Number of Target Users When Using a Cohort

When you use a Cohort for targeting or campaigns, the number of users actually included as targets from the Cohort varies depending on how it is used. Except for schedule-based sending, only up to 1 million users are included as targets.

Usage Method	Number of Users Included as Targets
Schedule-based sending	All Cohort members included
Event-based · API-based sending	Up to 1 million included
In-App Message	Up to 1 million included
A/B Test · Feature Flag · Remote Config	Up to 1 million included

For event-based sending, API-based sending, and In-App Messages, if the number of users included in the Cohort exceeds 1 million, only up to 1 million users are included in the campaign audience, and the rest are dropped from the target. Even if the campaign appears to work normally, note that the actual reach is limited to 1 million users.
