Hi,
Hope this finds you well; being solution providers for enterprise email delivery/high volume email delivery, we managed large databases of email records, by industry and geography. I can help you provide the list, in some of the lists, we do manage the data fields for first name and last name, but in some lists, it is only emails that are being maintained. However, the records belong to active DBs, qualified, mostly valid and have been used for sending campaigns. I'm willing to provide the sample of few records too so that you can test. Let's discuss.
Thanks
