We can provide you with enormous database of people interested in your websites as a part of your website promotion campaign. It is an excellent way to promote online. What needs to be remembered is that e-mail campaigns are different from spamming. Spamming is sending mails to people who are unknown, by way of origin or interest areas. Spamming has a very low turn around rate, very few visitors are likely to take your mail seriously.
Alternatively, E-Mail campaigns are sent to targeted users who have shown interest in receiving mails. These databases are available with sites, e.g. while registering for Hotmail or Yahoo the last but one screen prompts the user for information on his interest areas and also asks the user if he would like to receive mails in his selected areas of interest. Over a period of time, such sites have a database of users which has been classified as per their areas of interest and geographic location.
