Hi, I believe this is my kind of work. I have more than 1.5 years of experience in data mining and data building. The data I build is from various sources which includes LinkedIn, Individuals company websites, lots of google search, etc. I assure you that the email I provide would not have any sort of Hard bounces and prior to the delivery of the list I will verify the list manually. Also, will send a general email to check if I have any hard bounce. Also, I provide the following information in my lists - email, company, url, name, first name, middle name, last name, title, address, zip code, phone number, fax(if available) and industry classification.
