Yes, Meta (formerly Facebook) allows advertisers to create Custom Audiences by uploading customer lists containing identifiers such as email addresses and phone numbers. This feature enables businesses to target ads to individuals who have already shown interest in their products or services.
Creating a Customer List Custom Audience:
Prepare Your Customer List:
Compile a list of customer data, including identifiers like email addresses and phone numbers.
Ensure the data is formatted correctly, with each identifier in a separate column.
Upload the List to Meta:
Access the Audiences section in Meta Ads Manager.
Select “Create Audience” and choose “Custom Audience.”
Choose “Customer List” as the source and follow the prompts to upload your file.
Mapping and Matching:
Meta will hash the uploaded data and attempt to match it with user profiles on its platforms.
Including multiple identifiers (e.g., email, phone number) can improve match rates.
Best Practices:
Data Accuracy: Ensure that the customer information is accurate and up-to-date to enhance matching efficiency.
Privacy Compliance: Only use data from customers who have consented to receive marketing communications, adhering to Meta’s Custom Audience Terms.
Regular Updates: Periodically update your customer lists to maintain relevance and compliance.
By leveraging customer lists, you can effectively reach individuals familiar with your brand, potentially increasing engagement and conversion rates.
