Hi! 
 
I offer the service of mailing your advertising to millions contact forms on various sites. This is well suited for advert b2b offers. It is possible to sort the sites by country and, possibly, even by site topic (additional option). 
 
Also I make email spam sending. Send your ad to users and get thousands of unique visitors and leads to your website.
