The most cost-effective way to source LinkedIn profiles from a list of names and emails is to use a workflow that combines full names with company names for higher match rates. If you only have names and emails, you can extract the company domain from the email address, then enrich it to get the company name. Once you have the full name and company name, input these into Clay’s LinkedIn Profile URL enrichment to efficiently find LinkedIn profiles for your list. This approach maximizes accuracy and minimizes manual effort by leveraging available data and automation steps.
