I am interested to buy fresh (not older than 3 months) opt-in email addresses only Business2Customer.
If the list is resulted from your own sending email campaigns, or the list is opt-in, then that is what I need. I am not interested in old email lists, or email list extracted with spider software, or email lists bought from other persons. The list must NOT contain: duplicates, invalids, dropped and bounced emails. I will release the milestone only after I will verify the list with an online validation service. If your list will have more than 10% from not containing list, I am not interested.
Also interested in lists from: United States, Canada, Mexico, Argentina, Australia, New Zealand, China, Japan, India, United Arab Emirates, Turkey, Russia, United Kingdom, Portugal, Spain, France, Italy, Germany, Belgium, Netherlands, Switzerland, Austria and any other European countries.
