Hi @Anand - dataflo.io,
2 things you can do. Add audience list with firstname, last name, company name and job title and linked in will enrich the people data. If not this, you can upload company names and domains and also enrich company profiles and then put filters like job titles and stuff.
From emails, you can find company domains > Use rows/clearbit API to get company name from company domain and just upload the CSV in linkedin.
