please be honest, don't recommend a company you work for.. I would like to send one advertisement email to a huge number of people in a specific country. Is there a legal way to acquire legally a list of emails to which I can send my mail? is there a company you know which is trustworthy that can send my mail to its opt-in people? yahoogroups? google-groups? facebook? is there anyway to get a 3rd party totally independent company to monitor the number of emails sent? There are simply too many offers .... and I have no idea whatsoever who should be trusted.
My opinion is e-mail advertising is on its way out. This due to the increase in effectiveness of spam blockers built into e-mail clients coupled with new laws passed in the United States. General rule of thumb is would you click on the ad if you saw it? If it is in my inbox from a unknown sender the answer is no chance. I would not suggest it as your best option
