Email Promotion
There's a wide diversity of email marketing sources on the internet. However, care should be taken to avoid falling for Spam lists. These services will give you a list of several email addresses harvested from the internet and claim they are all opt-in. Usually there's no way to verify this, and in any case, they have not consented to receive email from you!
For several years now, ADSaturation and SuccessPub have been delivering some of the most reliable (if not the most reliable) email promotion services, delivering about 20 million messages every day.. Be sure to check them out if you are not already a member.
