I do know that Cody Moya has lists for sale. I haven't received an email advertising leads for a few weeks so I don't have a link to share. A good alternative is to use co-registration to have some one else send subscribers to your list. I do have a few suggestions when using co-registration.
When using co-registration there are a few things you can do to get a more responsive list.
1. They are going to ask for a description of you newsletter or email information you will be sending to your list. So make a good description of what you have to offer your subscribers. Be as percise as possible because you only want targeted subscribers who are interested in what you have to offer. After all you are paying for each subscriber. Have this ready ahead of time.
2. Always buy double opt-in subscribers. They cost a little more but you will know that the subscribers you are purchasing will be interested enough in what you have to offer to go through the whole double opt-in process.
3. Again this will cost a little more, but buy leads from USA, Great Britian,and Australia. You will get better results. That is why they cost more.
I did have a company that I would suggest but I can't find the information now. Just do a search for co-registration leads and you should be able to find several companies.
When choosing a company, make sure the company displays lists that are not all selected. Stay away from these companies. Your offers will be lost in a sea of other offers and will not get opened.
You want to choose a company that requires the potential lead to go down the list of newsletters and check only the ones they are interested in receiving. This will help get you more targeted subscribers.
If done properly, co-registration can be a good way to build a list of leads. In my coaching, I teach that a good way to get your first 1,000 list members is to use co-registration. This little list will give you enough leverage online to start doing some types of joint ventures like ad swaps for example. So buying a list is one way to get things rolling right away.
Co-registration leads will not be the best subscribers but following my suggestions above will make them much better.
Wishing you much online success,
