I have been into marketing for a very long time now. I know how marketing works, especially when it comes to online marketing, but also I know a thing or two about offline marketing. I know, for example, that in order to be a successful marketer, one needs to have access to mailing lists that can make such a huge difference in the life of every marketer.
Mailing lists that contain the addresses of people who might be interested in your products is very often the key to success. You will not get very far without them. Such lists can be easily obtained from places such as List Giant.
There is no limit to how many lists a person can buy. Usually, the more lists a person buys, the more successful he is going to be and the more people he is going to reach through his marketing campaigns. I recommend that you start building your database with the help of mailing lists and then add more and more contacts as the time passes by. Thanks to this strategy, you should be able to build a comprehensive list withing weeks or even days. It all depends on your determination to work towards your success and whether you want it to happen or not.
