Cohort Sync



This integration allows you to export Cohorts of users from Mixpanel to Segment so that you can better target users across many downstream connections.


You must be a Mixpanel project admin to enable the Segment integration.

Enable the Integration

This connection requires set up on both Segment and Mixpanel.

Segment Setup

The connection requires a Segment Write Key. You can obtain this key via Segment's UI:

  1. Log into your Segment workspace and click Sources under Connections in the menu bar on the left.

  2. Click Add Source button on the right side above the sources table.

  3. Search for Mixpanel Cohorts, select and hit next

Sync Types

There are two types of sync: one-time and dynamic. When you generate a one-time export or dynamic sync, it overwrites the previous export with an updated export that reflects users who qualify for the cohort at the time of export.


In this sync, Mixpanel sends Segment the static set of users who currently qualify for the cohort. The cohort data will not be updated in Segment after a one-time export.


In dynamic sync, Mixpanel initiates sync between a cohort and Segment every 15 minutes. The exported cohort will be updated every 15 minutes to reflect the most recent list of users in a cohort.

Verifying in Segment

Once the export completes, you can open the debugger on the source you created in Segment above and you'll see "identify" calls flowing in for each user that has been added or removed from the cohort.

Segment 7 Image

Mixpanel sets a property on the user's profile in Segment indicating whether they are currently part of the cohort.

We send the following identify call to Segment when a user enters the cohort:

  "type": "identify",
  "traits": {
    "Mixpanel - <Cohort Name in Mixpanel>": true,
  "userId": "" // we use the distinct_id property here

We send the following when a user exits the cohort:

  "type": "identify",
  "traits": {
    "Mixpanel - <Cohort Name in Mixpanel>": false,
  "userId": "" // we use the distinct_id property here
