Lookalike models are used to increase scale by finding new people likely to be interested in your business because they resemble existing customers.
You can use your CRM data to create lookalike audiences on Realize. If you upload either a customer list of hashed email addresses, mobile device IDs, or 5 digit US zip codes, Realize’s predictive engine will find similar users to your current customers in your database.
Note: Lookalike targeting is only available when targeting users in the US.

How to Create Lookalike Audiences
Create a lookalike audience in the Audiences page in your Realize account.
In the left menu of Realize, click “Audiences” > “+ New Audience.”
Select Predictive Audience under what you want the audience to be based on.
On the audience creation screen, select 'customer file,' enter the audience name and select the data type from Emails, Mobile Device IDs (IDFA or GAID), or Zip Codes.
Upload the customer file in CSV format.
In the Audience Properties section, select "Create an additional targeting audience from file" if you wish to create a custom audience based on the same customer file you're uploading.
Click “Create Audience” to save the audience. It will take two to three days for the lookalike audience segment to process. You can check the status of the audience you've created in the Predictive Audiences tab of the Audiences page.
How to Target Lookalike Audiences
Once the status of the lookalike audience segment changes to Ready, you can target or suppress it in existing or new campaigns. 2. Navigate to the Campaign Creation or Edit page.
3. In the Audience Targeting section, select the lookalike audience segment you wish to target or exclude under My Audiences.

Both iOS and Android device IDs are accepted.
The CSV file should contain a minimum of 2,000 and a maximum of 750,000 records and not exceed 100 MB.
