I would be cautious when dealing with people who sell these email lists. Half the time, the list does not match your target audience so you don't really get good value-for-money.
You might also see a high unsubscribe rate from these generated lists. Since these lists are auto-generated, it's possible that the people on it didn't confirm to opt-in to the list, so they will not recognize you or your newsletters and eventually unsubscribe.
Hope that helps. All the best!
