i too would like to build a relationship list to eventually sell to.. i have read posts from some of the most successful marketers and they all get great conversions from lists.

with so many different niches available to people do you have to build specific list for specific niches or can you pretty much sell anything in any niche to your list once established?

in terms of free giveaways for your list - how can you determine what is high value item that is suitable as a freebie giveaway?

i understand most lists builders give away ebooks but how do you know if its a suitable enough giveaway?

thanks
