Safelists
Send emails to opt-in members of the lists - you WILL receive emails from members in return, so don't get angry, just accept it
as part of the advertising process! I also recommend setting up 2 gmail email accounts (free & better delivery rates than most
free emails), one to use as your 'contact' email and one to use as your 'list' email - this will make more sense when you join a safelist! Adtactics EuropeanSafelist - the most responsive safelist I've used FreeSafelistMailer EliteSafelist GlobalSafelist GOTSafelist TheTrafficSecret VitalAdViews
