Improving Enrichment Hit Rate for Contact Data in Tables

Hi Support, I pasted into my table 596 rows of info with columns for first name, last name, company, job title, and email address with the intention of using the enrich person action to get the person's new company, job title and email if available. This run yielded 437 rows with 'no profile' found and I know some of it's incorrect due to a manual check in linkedin of some of the contacts. How do I get around this issue and get a better hit rate?
