Custom Audiences Overview

If you have a list of your customers (e.g., emails, phone numbers or Facebook user IDs), you can target your ads to them by creating a new Custom Audiences. View Tags are not yet permitted for Custom Audiences from your website clients. Only Atlas view tags are accepted at this time.

To create a Custom Audience, navigate to the custom audiences section of the library (in the Campaigns view, this can be accessed from the three-dot menu under Account Library -> Custom Audiences).

New custom audiences can be created from the Create custom audience -button → Custom Audience from File.

You can create the custom audience by:

• Uploading a CSV or text file OR
• By directly copying and pasting the contact information into Smartly.io.

Note: Facebook will not include emails uploaded with @facebook.com addresses to custom audience. This to ensure that advertisers are creating high quality ads that meet Facebook's data consent terms of service.

Phone number formatting guidelines:

• Country code + Area Code + Number
• No leading zeros from country code
• Numeric characters only
• Eg.: 16505551234, 16505551235

Uploading the Contact Information to Smartly.io

When adding custom audiences through Smartly.io you first select the type of contact information and then upload the information from a file or by manually copy-pasting it. If you copy-paste the information you must remember to include in the first line the name of the identifier that you are pasting (Email, Phone, Facebook User Id or Mobile Advertiser Id)

After selecting the information that you want to upload you would be able to check the formatting of each column and correct possible errors. All the data that we send will be encoded before being sent to Facebook, but if you want to provide us Emails and Phone numbers already encoded you can change the name of the column to Email (hashed)Phone (hashed) and we will avoid hashing those columns again.
