I have recently purchased a website which has a list of more then 24.000 email subscribers. They were subscribed to a weekly newsletter about "free stuff and discount offers" on Croatian language and i never emailed them since i purchased the site few months ago. Subscribers are from ex-yu countries - Croatia, Serbia and Bosnia & Herzegovina and they all understand Croatian language.
Since i dont know anything about email marketing i am thinking of selling the list. How much do you think i should consider as a fair offer for it? Am i even allowed to sell it?
