Marketing Beginner

Hi there. I bought a few days ago Income Infuser. This program put my website up, I do not promote clickbank products or amazon products, I have my own products to sell. I have 3 OTO Offers and like 5 Products in User's control panel and an affiliate program too.
I don't really know how to get subscribers, I have only 30. I thought to buy a solo mailing but don't know if it really worth.
I have a 12,500 emails database and I'm looking for a SMTP Server to send them, will I get any subscribers?
Sorry for my bad english. XD

Solo ads are definitely worth looking into. If not maybe consider PPV

solo ads are the best way for this, use solos until your list is big enough for swaps and than do swaps on a regular basis. I don't see how mailing the list you have from somewhere will be worth your time and money, they'll probably have a huge bounce rate.
