Notifly (Cohort Sync)

The Notifly destination allows you to sync your Amplitude-built cohort to your Notifly user group for targeting purposes.

Use cases

  1. Cart Abandonment Recovery: Sync a cohort of users who added items to their cart but didn't complete checkout to Notifly, then trigger a user journey with a series of reminder notifications offering incentives to complete their purchase.
  2. Feature Adoption Campaigns: Create a cohort of users who haven't tried a new feature and sync it to Notifly to run a targeted campaign with in-app messages and push notifications demonstrating the feature's value and driving adoption.
  3. Win-Back Inactive Users: Identify users who haven't opened the app in 30 days, sync this cohort to Notifly, and set up a user journey that sends a sequence of messages with personalized content, special offers, or updates to re-engage them.

Considerations

  • This integration maps an Amplitude user ID to the external_user_id of a Notifly user.
  • This integration doesn't support anonymous users. Each user must have a user ID to be identified across Amplitude and Notifly. Ensure that the selected user property exists in both Amplitude and Notifly.
  • Notifly creates one user group per cohort. To avoid cohort discrepancies, each new sync for the same cohort resets the existing user group. (Note: "new sync" refers to a newly added destination.) Be careful when syncing again with a different mapping.

Notifly setup

In Notifly, navigate to Settings. Copy the Project ID and API Credentials (Access and Secret Key).

Amplitude setup

  1. In Amplitude Data, navigate to Catalog > Destinations tab.
  2. In the Cohort section, click Notifly.
  3. Enter a name, your Notifly Project ID, Access Key, and Secret Key.
  4. Map an Amplitude user ID to the Notifly external_user_id. You can choose any pre-defined or custom user property in Amplitude to serve as the user ID.
  5. Save when finished.

Send a cohort

  1. In Amplitude, open the cohort you want to export. Click Sync, and choose Notifly.
  2. Choose the destination.
  3. Select the sync cadence.
  4. Save your work.

Note

For scheduled cohort syncs, only the initial sync includes the full cohort. All subsequent syncs include all additions and removals since the last sync.

Cohorts in Notifly

After you send your Amplitude cohort to Notifly, it appears in the User Groups section of the Notifly dashboard. Cohorts sent by Amplitude include an "(Amplitude)" suffix in the name.

Notifly only ingests users for whom they have identifiers.

Example

User A, User B, and User C are in the Amplitude cohort (Cohort 1). Notifly only has identifiers for User A and User C. Notifly creates a user group that includes User A and User C, and drops User B.
