What LinkedIn targeting criterion allows you to upload a pre-existing customer list for precise audience matching?

LinkedIn's 'Matched Audiences' targeting criterion allows you to upload a pre-existing customer list for precise audience matching. This feature enables marketers to target LinkedIn members who are already in their CRM or customer database. You can upload lists of email addresses or mobile phone numbers. LinkedIn then matches these against its member database. The process involves hashing (encrypting) the data to protect user privacy. Matched Audiences are used to retarget existing customers with specific offers, exclude them from certain campaigns, or create lookalike audiences. Lookalike audiences expand your reach to LinkedIn members who share similar characteristics and behaviors with your existing customer base. For example, a company could upload a list of their highest-value customers to target them with a premium product offering, or they could exclude existing customers from a campaign designed to acquire new customers. The success of Matched Audiences depends on the quality and accuracy of the uploaded data, as well as the match rate between the uploaded list and LinkedIn's member profiles.
