How to Identify SDR/BDR Names in Company for Email Copy

Hey everyone I have this line in my email copy, could you please help me how can I get name of SDR/BDR in their company “I had to assume you are using outbound tactics considering {full name of SDR} is an {SDR/BDR} at {company}.” I tried quite a few tricks with Clay like use Chatgpt-4 to review company linkedin profile and tell me full name of SDR, then using linkedin enrichment by entering job titles keyword to get name of SDRs but even when I used linkedin enrichment from 68 prospects it only gave me data of 5 peoples, whereas for others it said no data found. Do you have any suggestion on how can I do this better?
