Well, it is possible that although the party claims that the lists are opt-in, they could be lying about it. The only true opt-in list would be those which you gather yourself from people who actually comes to your site and sign up for announcement.
The people on the list may have sign up for something but do not know it would be used by you since you are a party to the list after the information has been collected. So they may assume it is spam.
Personally if I were you, I would not purchase such a list.
Originally posted by sportstoto33 hi, recently I plan to buy some high quality fresh leads to use in my eBook Website.
The leads that I plan to buy is fresh lead (7-30 days old), and it is targeted leads. But it is single optin.I am confusing whether it will lead me into trouble.
It will, without a doubt, lead to trouble for both you and your host. "single opt-in" means that the addresses are unconfirmed and could have come from anyplace with or without the address owner's knowledge or permission. They were probably harvested, and I can promise you that they're not 'targeted'.
What if I import all into my mailing list and send newsletter to them? Will it cause my host to close me down?
