I have 20,000+ emails industry specific. I got them from datadepot.com. I want to send out our ad to these people. How do I do that? Can i use constant contact or aweber? What are the spam laws? Do I give another company our email addresses to mail it out for us? that doesn't seem right becaues then they just got 20,000 free email addresses? does email marketing work anymore?
any info is appreciated.
also, what is your opinion on services like datadepot,optinservices.com, etc?
